boost: updated to 1.85.0
Version 1.85.0
New Libraries
Charconv:
A high quality implementation of <charconv> in C++11, from Matt Borland.
Scope:
A collection of scope guard utilities and a unique_resource wrapper, from Andrey Semashev.
Updated Libraries
Asio:
Fixed the async_result primary template's concept checking to correctly handle lvalue-qualified completion signatures.
Fixed some compile errors that could arise when using the bind_allocator, bind_executor, bind_immediate_executor and bind_cancellation_slot completion token adapters to adapt each other.
Changed the experimental::ranged_parallel_group operation so that it moves the completion_order vector when invoking the completion handler.
Fixed some warnings about deprecated implicit copy constructors on ip::basic_resolver_query, io_context::strand, and coroutine.
Updated the version specification used to initialise Winsock.
Fixed co_spawn to correctly propagate exceptions resulting from cancellation to the completion handler.
Added calls to std::launder to fix undefined behaviour in awaitable<> internal storage.
Added missing handling of the file_base::append flag in the Windows implementation of file support.
Updated the socket and descriptor implementations to add more cases where they will fall back to fcntl if a call to ioctl fails.
Fixed the boost/asio/experimental/parallel_group.hpp header so that it is self-contained.

Bimap:
Fixed heterogeneous lookup for side collections
Bind:
C++03 is no longer supported; a C++11 compiler is required. (This includes GCC 4.7 or later, and MSVC 12.0 (VS 2013) or later.)
Conversion:
Removed outdated mentions of boost::lexical_cast that is not part of the library any more. Thanks to Danil Sidoruk for the PR
Core:
Added a new boost/core/functor.hpp header with a functor class template for wrapping a raw function into a function object class.
Changed null_deleter, fclose_deleter and checked deleter definitions so that they don't bring namespace boost into argument-dependent lookup. Users may need to either explicitly qualify the namespace of the called function or add a using-declaration.
Filesystem:
path::generic_path and path::generic_string methods now remove duplicate directory separators in the returned paths.
v4: path::generic_path, path::generic_string, path::make_preferred and path::lexically_normal avoid converting between backslashes and forward slashes in path root names. For example, on Windows, path("\\\\\\\\?\\\\c:\\\\foo").generic_string() now returns "\\?\c:/foo" instead of "//?/c:/foo". Similarly, path("\\\\\\\\host/share/foo/..").lexically_normal() now returns "\\host\share".
v4: equivalent now indicates error if either one of the paths doesn't exist.
v4: absolute now returns a path with a trailing directory separator when the input path has an empty relative_path().
Added a unique_path overload taking a single error_code& ec argument. The overload generates a unique path using the default path model.
weakly_canonical now produces an absolute path if the input path is relative and contains no elements that exist in the filesystem.
Added a new copy_options::ignore_attribute_errors option for copy_file and copy operations. The new option allows to ignore possible errors while copying file attributes.
On Linux, copy_file backends based on sendfile and copy_file_range system calls will attempt to preallocate storage for the target file. This may reduce filesystem fragmentation and provide early error indication if there is not enough free space. Not all filesystems support this feature; file copying proceeds if storage preallocation is not supported.
On POSIX systems that support fdopendir, openat and related APIs defined in POSIX.1-2008, as well as on Windows, recursive_directory_iterator now uses file descriptors/handles instead of paths to query the file statuses and open nested directories during iteration. This makes directory iteration more resilient to concurrent modifications of the filesystem.
Removed APIs that were previously declared deprecated. In particular, path and recursive_directory_iterator member functions, is_regular, copy_directory, symbolic_link_exists, complete, copy_option, symlink_option, as well as boost/filesystem/convenience.hpp and boost/filesystem/path_traits.hpp headers were removed. Possible replacements for the removed components are mentioned in the documentation.
Support for path construction, assignment and appending from container types (e.g. std::vector<char>) is now disabled by default. Users can still enable this functionality by defining BOOST_FILESYSTEM_DEPRECATED. This functionality remains deprecated and will be completely removed in a future release.
Function:
C++03 is no longer supported; a C++11 compiler is required. (This includes GCC 4.7 or later, and MSVC 12.0 (VS 2013) or later.)
Geometry:
Improvements
Use if constexpr macro instead of condition macro
Pass strategy to sort by side
Add cmake files for clang/mac/darwin/arm64
Solved issues
Fix invalid set operations for CCW polygons

Various fixes of errors and warnings
Iterator:
Support for C++03 is deprecated and will be removed in a future release.
JSON:
Boost.Endian is now used to deal with endianness.
Aliases to Boost.System and Boost.Container components are deprecated and will be completely removed in 1.87.0.
Conversion of described classes supports private members.
Rvalue reference overload for visit.
Add conversion support for path-like types.
Parsing into described classes correctly considers inherited members.
Conversion of self-referential sequences is disabled.
Fixed reference handling in visit.
LEAF:
New API for transporting of error objects and exceptions between threads: try_capture_all.
result<T> able to transport exceptions captured via try_capture_all.
result<T> transporting dynamically captured error objects with improved efficiency.
Old make_shared_context/capture APIs are deprecated, will be removed in the next release.
Removed support for transporting of dynamicaly captured error objects in exceptions.
LexicalCast:
Significant rewrite of the internal logic to separate optimized and C++ Standard Library IO-based streams:
C++ Standard Library based streams now constructed in less cases leading to better performance;
less template instantiations and simpler code;
always use std::char_traits (do not use custom traits from input/output types as it leads to linktime or runtime errors);
fixed missuse of forward declared boost::array
support for volatile input types was dropped, following the C++ Standard Library trend.
Optimized conversions from std::basic_string_view and boost::basic_string_view.
Dropped dependency on Boost.NumericConversion and Boost.MPL. Fixed some cases of converting floting point types to arithmetics.
The library now compiles and works fine with -fno-sanitize-recover=integer.
Locale:
Fix linker issues due to missing typeinfo for char8_t in C++20 mode
Fix IConv compile flags when using ICU that has a bundled IConv
collator now throws on construction, if at all, as documented
collator no longer derives from std::collator to avoid possible type confusing when it isn't available for the current backend
Throw an exception when a faulty IConv library is detected (e.g. on some MacOS versions) instead of looping indefinitely
Reduce resolution of date_time to seconds as milliseconds where not easily available causing confusion
Math:
Added a new collection of optimization algorithms:
Differential Evolution
JSO
Random Search
CMA-ES
Fix Divide by 0 warning in NCF survival function
Fix constexpr depth limits of ccmath::floor/ceil fail for large arguments
Improve accuracy of quartic_roots
Fix cstdfloat numeric limits detection macro for libstdc++14
Fix for MSVC UCRT defining _Complex_I in complex.h when using C++14
Improve cstdfloat iostream
Fix redefnition of Boost.Config macros when using standalone mode in a non-standalone environment
Significant improvements to code coverage with associated bug fixes
MSM:
Major Update. Backend update (back11). Requires C++ 11. The documentation now uses it as default.
Big new feature. New front-end (PlantUML). Requires C++ 20
Various Bugfixes (compiler errors and warnings, priority of deferred events)
Multi-index Containers:
Fixed documentation errors.
Multiprecision:
Fix deprecation warnings from C++23 <limits>
Fix cpp_bin_float for small bit counts
Fix -Wpessimizing-move
Add covecov runs
Reduce truncation in cpp_dec_float multiplication
Fix complex_adaptor to match precision requirements
Fix for breaking changes in tommath
Fix for types that can be converted to number participting in arithmetic operator overloads
MySQL:
Breaking change: Boost.MySQL now requires linking to the new Boost.Charconv compiled library. This addresses a locale-dependency problem, increases efficiency, and powers the new client-side SQL formatting feature.
Added experimental support for connection pools, which allows re-using sessions and provides built-in reconnection and error handling.
Added experimental support for type-erased connections (any_connection class). any_connection is not a template and features simpler connection establishment and reconnection semantics.
Added experimental support for client-side SQL formatting functions (format_sql and format_sql_to). These allow securely composing queries client-side, which enables patterns like batch inserts, dynamic filters or PATCH-like updates.
Fixed a performance issue affecting close_statement and async_close_statement that could cause significant delays in application code.
Added support for building with BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT.
The deprecated execution interface (connection::query, connection::start_query, connection::execute_statement, connection::start_statement_execution and their async counterparts) now triggers warnings, as it's scheduled for removal in Boost 1.86.
Fixed a bug that caused some error messages to be truncated.
Warning cleanup. Builds are now clean from warnings when building with -Wall and -Wextra.
All field_view constructors are now stable.
The library internals have been rewritten using a sans-io approach to reduce complexity.
Odeint:
Breaking change: The library now explicitly requires C++14 instead of implicitly by including Boost.Math
Fix compatibility with Thrust 1.10.0
Removed C++03 Boost components:
Array
Bind
Function
Static_assert
PFR:
boost::pfr::get_name now can work with local types on some compilers. Thanks to Bela Schaum for the PR
Removed unused implementation details. Thanks to Denis Mikhailov for the PR
Allow throwing exceptions from boost::pfr::structure_to_tuple. Thanks to Denis Mikhailov for the bug report.
Field reflection trick is now described in the docs.
Random:
Added splitmix64 PRNG
System:
C++03 is no longer supported; a C++11 compiler is required. (This includes GCC 4.8 or later, and MSVC 14.0 (VS 2015) or later.)
The deprecated header boost/system/cygwin_error.hpp has been removed.
The original and obsolete (32 bit) MinGW is no longer supported. MinGW-w64 (both 64 and 32 bit) is still supported.
operator& now works for result<void> (by way of taking a nullary function.)
Added operator|= for result.
Stacktrace:
Big new feature: stacktrace from arbitrary exception. On some POSIX platforms std::stacktrace::from_current_exception() now returns the stacktrace of the current exception object as if the stacktrace was captures at the point of throwing the exception. Many thanks to Andrei Nekrashevich for prototyping the idea in libsfe.
Fixed memory consumption on Windows with boost_stacktrace_windbg.
Fixed library build with non hidden visibility.
Added a separate section on async signal safety to the docs.
STLInterfaces:
Change the behavior of iterator_interface for input iterators in C++20 and later, to more closely follow the C++20 concepts.
Remove hidden friends from iterator_interface to fix errors about concepts being redefined with different constraints.
Add a new v3 inline namespace, containing a new iterator_interface based on deducing this instead of CRTP (C++23 and later).
Add an rvalue-qualified overload of closure::operator(), to prevent dangling temporaries.
Test:
Respect library-spcific _NO_LIB macros
Supress MSVC C4702 from __builtin_unreachable() on intentionally unreachable code
Fix boost::function streaming error
Unordered:
Optimized emplace() for a value_type or init_type (if applicable) argument to bypass creating an intermediate object. The argument is already the same type as the would-be intermediate object.
Optimized emplace() for k,v arguments on map containers to delay constructing the object until it is certain that an element should be inserted. This optimization happens when the mapãàÑÔ key_type is move constructible or when the k argument is a key_type.
Fixed support for allocators with explicit copy constructors
Fixed bug in the const version of unordered_multimap::find(k, hash, eq)
Variant:
Removed more of the pre-C++11 macro and workarounds.
Wave:
Fixed bugs:
Emitted pragmas lack terminating newline
YYMARKER not updated when fill called on BOOST_WAVE_BSIZE boundary
Updated Tools
Build:
Includes release of B2 version 5.1.0.

boost: updated to 1.83.0 1.83.0 New Libraries Compat: A repository of C++11 implementations of standard components added in later C++ standards, from Peter Dimov and contributors. Updated Libraries Any: New boost::anys::unique_any C++11 class - an alternative to boost::any (or to std::any) that does not require copy or move construction from the held type. Ported documentation to Quickbook, Doxygen comments now used in code. Atomic: Fixed compilation of atomic_ref for const-qualified types. Note that even const-qualified atomic objects must still reside in read-write memory. Chrono: Remove use of deprecated Boost.Ratio features. Compat: Added latch.hpp, an implementation of std::latch (contributed by Christian Mazakas.) Added shared_lock.hpp, a (partial) implementation of std::shared_lock (contributed by Christian Mazakas.) Core: Added support for incomplete types to boost::core::type_name. Bit manipulation functions in boost/core/bit.hpp are now constexpr on recent MSVC versions (VS2019 update 5 and later.) Added boost::core::byteswap (an implementation of std::byteswap from C++23) to boost/core/bit.hpp. Moved the yield primitives sp_thread_pause, sp_thread_yield, sp_thread_sleep from SmartPtr implementation details to boost/core/yield_primitives.hpp. DLL: Fixed tests failures on glibc 2.36+, thanks to [oà n Trầî Công Danh](https://github.com/sgn) for the bugreport. Filesystem: Added directory_entry::refresh method that updates internal cached file statuses for the directory entry identified by path. v4: directory_entry constructors and modifiers that initialize or modify the path now automatically call refresh. This may result in errors that were not indicated before and in v3, if querying the filesystem for file statuses fails (e.g. if the file does not exist). This new behavior is similar to std::filesystem. v4: directory_entry constructors and methods taking file_status parameters are removed. Users are recommended to remove these arguments and rely on directory_entry calling refresh internally. Added directory_entry member methods for checking the file type of the file, similar to std::filesystem. Added more methods for testing file status: is_block_file, is_character_file, is_fifo, is_socket and is_reparse_file. recursive_directory_iterator is now more likely to reuse information about the file type that is obtained during filesystem iteration. This may improve performance. File streams defined in boost/filesystem/fstream.hpp are now movable, if the standard library file streams are. Added a new header boost/filesystem/cstdio.hpp with a portable fopen overload that takes path as the first argument. This function is equivalent to std::fopen, except that on Windows it uses the native wide character encoding for paths. Generic path comparison operators are now more restricted to avoid potential ambiguities when user's code contains a using namespace boost::filesystem; directive. Fixed potential overload resolution ambiguity in users' code, where path constructors from iterators could interfere with function overloads taking a std::initializer_list argument. On Windows, added more workarounds for errors returned by various filesystems when creating a directory iterator. On Windows, relaxed access rights needed for querying file times. Flyweight: Added smart-pointer syntax to boost::flyweight (operator* and operator-> dereferencing to the underlying value). Fixed a situation where the mutex used by simple_locking was not recursive. Geometry: Improvements Drop dependencies and replace boost with std in several places Add missing headers so that all headers compile independently complying with Boost policy Check const Ring concept in calculate_point_order Solved issues Fix for union Fix for different geometry types Fix for convex hull Fix within algorithm for geometries having a pole as a vertex Various fixes of errors and warnings Iterator: Added is_iterator type trait that allows to test whether the type qualifies as an iterator type. filter_iterator now supports move-construction of the adopted iterator and the function object. JSON: The library now only throws system_error, except for when allocation failed, in which case std::bad_alloc is thrown. Serialization behavior can now be changed by serialize_options. Contextual conversions. Parser option for more precise number parsing. Support parse_options in stream operator<<. Parser option to allow Infinity and NaN JSON literals. Parser mode that only validates numbers rather than parsing them. Numbers with exponent larger than INT_MAX are accepted by the parser and treated as infinity. Fix object member functions that should provide strong guarantee. Fix ambiguity of end call when boost/range.hpp is included. Fix ASan failures. Fix error message for error::size_mismatch. Fix conversion into tuple with const elements. Locale: Bitwise/binary operators (left/right shift, binary and/or/xor/not) are no longer supported in message catalog files matching GNU gettext behavior Std backend on Windows uses the classic locale instead of the system locale when the requested locale does not exist (now same as on other OSs) localization_backend_manager::get is deprecated, use the generator instead New converter classes as alternative to to_utf/from_utf/between Fix UB on invalid index in format strings Fix conversion of UTF to e.g. iso-2022-jp on Windows without ICU Use long long as the count parameter for pluralized translations Fix movability and exception specification for some classes Log: Fixed a possible infinite loop in text_file_backend, when the size of a formatted log record exceeds the rotation_size limit. Math: Added Numerical evaluation of Fourier transform of Daubechies scaling functions 921. Added logcdf function to statistical distributions 946. Added support for C++23's <stdfloat> types 978. Fixed various -Wmaybe-uninitialized warnings Fixed round and trunc functions for non-representable numbers 968. Fixed calculation of mode for F-distribution 976. Fixed overflow in beta distribution 977. Fixed overflow in hypergeometric distribution 987. Fixed calculation of median absolute deviation with non-zero center 997. Mp11: Added an offset/from parameter to mp_from_sequence, mp_iota, mp_iota_c. Added mp_value, mp_list_v, mp_rename_v, mp_is_value_list. Added value list support to the primitives in <boost/mp11/list.hpp>. Added value list support to mp_repeat, mp_fill, mp_at, mp_back, mp_take, mp_pop_back, mp_drop, mp_insert, mp_erase. Multi-index Containers: Updated range insert in non-unique ordered indices to preserve insertion order of equivalent elements. Serialization now uses std::size_t instead of unsigned long to save and load the size of a multi_index_container (unsigned long is smaller than std::size_t in LLP64 data models). multi_index_container serialization class version has been bumped from 3 to 4 to reflect this change. Multiprecision: Fixed bug in rational adapter division 542. Fixed handling of global precsion changes in multi-threaded environments 552. Fixed cpp_int::eval_convert_to noexcept specification 555. MySQL: Major update. Stored procedures are now fully supported, including SELECT statements producing data and procedures with OUT parameters. Added support for multi-queries, which allows running multiple semicolon-separated statements with a single call. A statically-typed interface has been added, which allows parsing query results into user-provided types, using Boost.Describe structs and tuples. Text queries and prepared statements can now be executed using the new connection::execute and connection::start_execution functions (and their async counterparts). These superseed connection::query, connection::execute_statement, connection::start_query and connection::start_statement_execution. The new functions allow access to new features, like the static interface. A separate compilation mode has been added to help reduce build times. Sources are included in boost/mysql/src.hpp, which must be included in exactly one translation unit. Prepared statements can now be executed using an iterator pair to specify parameters, using statement::bind and connection::execute. This enables use cases where the number and type of parameters is not known at compile-time. Prepared statement execution now accepts parameters of type bool, std::optional and boost::optional. Added error codes and verified compatibility with MySQL v8.0.33 and MariaDB v11.0. Fixed potential problems with Windows' min() and max() macros. All assertions now use Boost.Assert. All exceptions are now thrown via Boost.ThrowException. Immediate completions are now correctly dispatched through the I/O object executor. Ratio: Change default BOOST_RATIO_VERSION to 2. Support for BOOST_RATIO_EXTENSIONS is now deprecated and will eventually be removed when Boost.Ratio is implemented in terms of the standard <ratio> header. Test: Added addtional older platforms to CI system (e.g. GCC 4.6) Fixed handling of uintptr_t to make sure it is portable on 32-bit systems 353. Fixed warnings from -Wdeprecated-copy-dtor and -Wdeprecated-copy-with-user-provided-dtor 375. Fixed handling of check_is_close for C++23 <stdfloat> types 382. Timer: Remove dependency on Boost.Chrono, Boost.System, and others. Disable deprecated headers unless BOOST_TIMER_ENABLE_DEPRECATED is defined. Unordered: Major update. Added boost::concurrent_flat_map, a fast, thread-safe hashmap based on open addressing. Sped up iteration of open-addressing containers. In open-addressing containers, erase(iterator), which previously returned nothing, now returns a proxy object convertible to an iterator to the next element. This enables the typical it = c.erase(it) idiom without incurring any performance penalty when the returned proxy is not used. URL: parse_query does not recreate string_view. url_view/string_view constructor requires non-url_view_base. IP-literal can be IPv6addrz. UUID: Improved generated x86 code for AVX targets. Removed the use of lddqu instruction on SSE3 targets, which penalize performance on Intel NetBurst CPUs but is more optimal on Skylake and later CPUs. Variant2: Added uses_double_storage(). Updated Tools Build: Includes release of B2 version 4.10.1.

them outside of the spawned "thread".
+ Fixed spawn to ensure the completion handler is dispatched through the
correct executor.
+ Fixed cleanup of of terminal-state spawn "thread" objects.
+ Fixed spawn and co_spawn implementations to dispatch cancellation
handlers on the correct executor.
+ Changed semantics of 'dispatch' to mean the executor is used as-is.

+ Support for per-operation cancellation
+ C++20 awaitable examples.
+ websocket per-message compression options
+ websocket timeout option api
+ multiple content length error
+ Support for default-completion and rebind
* Container Hash:
+ Major update.
+ The specializations of boost::hash have been removed; it now always
calls hash_value.
+ Support for BOOST_HASH_NO_EXTENSIONS has been removed. The extensions
are always enabled.
+ All standard containers are now supported. This includes std::
forward_list and the unordered associative containers.
+ User-defined containers (types that have begin() and end() member
functions that return iterators) are now supported out of the box.
+ Described structs and classes (those annotated with
BOOST_DESCRIBE_STRUCT or BOOST_DESCRIBE_CLASS) are now supported out of
the box.
+ hash_combine has been improved.
+ The performance (and quality, as a result of the above change) of
string hashing has been improved. boost::hash for strings now passes
SMHasher in 64 bit mode.
+ The documentation has been substantially revised to reflect the
changes.
* Core:
+ empty_value members are now marked as constexpr.
+ Added fclose_deleter, a deleter that calls std::fclose on a pointer to
std::FILE.
+ Bit manipulation utilities in boost/core/bit.hpp now explicitly require
unsigned integers on input. (#129)
+ bit_width now returns int instead of a value of the input argument
type. This follows resolution of LWG3656.
* Describe:
+ To allow the inclusion of enumerators.hpp, bases.hpp, and members.hpp
when the option -pedantic is used, the invocation of
BOOST_DESCRIBE_ENUM has been moved from modifiers.hpp into a separate
header, modifier_description.hpp. As a consequence, modifiers.hpp no
longer includes enum.hpp. Code that has been relying on this implicit
inclusion may fail, and will need to be fixed to include enum.hpp.
* DLL:
+ Fixed path_from_handle implementation for Windows platforms, thanks to
@SaltfishAmi for the bug report 57.
* Filesystem:
+ Deprecated: path construction, assignment and appending from containers
of characters, such as std::vector<char> or std::list<wchar_t>, is
deprecated in v3 and removed in v4. Please use string types or
iterators instead.
+ Deprecated: boost/filesystem/path_traits.hpp header is deprecated and
will be removed in a future release. The header contained
implementation details of path and should not be used in user's code.
+ Previously deprecated APIs will now generate compilation warnings on
use. To suppress these warnings, BOOST_FILESYSTEM_ALLOW_DEPRECATED
macro can be defined when compiling user's code.
+ Fixed compilation due to a missing include on POSIX systems that do not
support *at APIs. (#250)
+ On Windows prior to 10, added a workaround for network share filesystem
that produces ERROR_INVALID_PARAMETER when constructing directory
iterators. (PR#246, #245)
+ On Windows, fixed weakly_canonical failing with an
ERROR_INVALID_FUNCTION error code if the path started with the "\\?\"
prefix. (#247)
+ Added support for std::string_view, boost::string_view and boost::
container::string (as well as respective wchar_t counterparts) in path
constructors, assignment and appending operations. (#208)
+ path constructors, assignment and appending operations taking a pair of
iterators will no longer accept iterators with value types that are not
one of the supported path character types.
+ On Windows, improved compatibility of directory_iterator with various
mounted filesystems and Wine releases prior to 7.21. (#255, #266)
+ On Windows, deduplicated files are now reported as regular files rather

* Iterator:
+ function_output_iterator now supports perfect forwarding of the
assigned values to the wrapped function object. (PR#73)
+ Fixed compilation of constructing a function_input_iterator from result
of post-incrementing another function_input_iterator. (#75)

Version 1.80.0
Known Issues
These are patches from library authors which were found too late to be fixed in
the release.
* Config
+ Support for libcpp15 which removes std::unary_function and std::
binary_function. Patch.
* Filesystem
+ Directory iterators may fail to construct for a network share on
Windows prior to 10, see PR#246 and #245. Patch.
+ On Windows, weakly_canonical fails to process paths that start with the
"\\?\" prefix, see #247. Patch.
+ On POSIX systems that don't support *at APIs, compilation fails due to
a missing include, see #250. Patch.
* Unordered
+ Containers are not in a valid state after moving, see #139. Patch.
+ Fix MSVC /RTCc build runtime failures. Patch.
New Libraries
* No new libraries.
Updated Libraries
* Asio:
+ Added a deduced trailing return type to all asynchronous operations, to
enable the new form of async_result for C++11.
+ Moved append, prepend, as_tuple, and deferred to the boost::asio
namespace, and made them compatible with C++11.
+ Made experimental::parallel_group compatible with C++11.
+ Added buffer() overloads for contiguous containers, such as std::span.
+ Added the ability for awaitable<>-based coroutines to directly co_await
operations that are packaged as function objects.
+ Changed spawn() to be a completion token-based asynchronous operation,
and added support for cancellation. The basic_yield_context token now
supports move-only and variadic result types. When targeting C++11 and
later, spawn() and basic_yield_context are implemented in terms of
Boost.Context directly.
+ Added the is_async_operation trait and async_operation concept.
+ Added the completion_signature_of trait.
+ Added converting move construction/assignment to posix descriptors,
serial ports, pipes, Windows object_handle, Windows stream handles, and
Windows random-access handles.
+ Added release() member functions to pipes, Windows stream handles, and
Windows random-access handles.
+ Enabled support for Endpoint implementations that return void pointers
from their data() member functions, as per the documented Endpoint type
requirements.
+ Removed all() and race() from experimental::promise, as experimental::
parallel_group covers this functionality.
+ Added source locations to exceptions and error codes produced by the
synchronous and asynchronous operations.
+ Fixed compatibility with OpenSSL 3.0.4 and later.
+ Fixed compatibility with with -masm=intel.
+ Explicitly stated that socket shutdown() calls are thread-safe with
respect to certain other synchronous operations on the same socket.
+ Optimised the move construction of I/O objects where only the executor
type differs.
+ Fixed the detection of std::invoke_result for clang/libc++.
+ Fixed an issue where experimental::parallel_group initiation
incorrectly moved arguments instead of forwarding them.
+ Fixed a sequencing issue in the implementation of post(), dispatch(),
and defer().
+ Fixed the awaitable<> implementation to propagate exceptions from
awaited initiation functions through the current completion handler.
+ Fixed detection of std::aligned_alloc with gcc 7.
+ Changed to avoid using the soon-to-be-deprecated std::aligned_storage
on newer compilers.
+ Fixed detection of std::aligned_alloc for older Apple platforms.
+ Removed faulty assertions from experimental::coro implementation.
+ Added defence against Qt-defined macros when building with Intel C++.
+ Changed the implementation of the select_reactor, on Windows, to ensure
that any exception resulting from failure to recreate its interrupter's
sockets will be allowed to propagate out through io_context::run().
+ Fixed various compiler warnings.
+ Updated all composed operations examples, and the C++11 timeouts
example, to use the new async_result form.
+ Added composed operation and coroutine examples for C++20.
+ Consult the Revision History for further details.
* Atomic:
+ Improved portability of endianness checks on ARM, AArch32 and AArch64
targets. (#59)
+ Fixed compilation with MSVC 14.0 (Visual Studio 2015) in C++17 mode. (#
61)
* Filesystem:
+ On Windows, added a fallback implementation for querying file
attributes in case if the file cannot be opened with
ERROR_ACCESS_DENIED error. This may allow status and symlink_status to
succeed for system files and directories that are not reparse points or
symlinks. (#234)
+ On Windows, added a workaround for FAT/exFAT filesystems that produce
ERROR_INVALID_PARAMETER when querying file attributes. This affected
status and symlink_status, which reported that files do not exist, and
directory iterators, which failed to construct, as well as other
dependent operations. (#236, #237)
+ Worked around a compilation problem on RTEMS. (PR#240)
+ On Linux, corrected switching to sendfile copy_file implementation if
copy_file_range failed with ENOSYS in runtime. The sendfile fallback
implementation used to skip the filesystem type check and could fail
for some filesystems.
+ On POSIX systems supporting openat and related APIs defined in
POSIX.1-2008 and on Windows Vista and later, improved protection of
remove_all against CVE-2022-21658 that was implemented in the previous
release. The previous fix could still result in removing unintended
files in certain conditions. Other systems remain vulnerable.
* GIL: NOTICE: We are planning BREAKING switch to C++17 as minimum required
C++ language version in one or two releases after Boost 1.80 (#676)
+ Added
o GSoC 2020: Added Perona-Malik anisotropic diffusion algorithm (PR#
500)
o GSoC 2020: Added histogram class and related functionality (PR#499)
o GSoC 2020: Added histogram equalization feature (PR#514)

hstack) or vertically (vstack) (PR#506)
o GSoC 2020: Added adaptive histogram equalization algorithm (PR#516)
o GSoC 2020: Added Standard Hough Transform and circle rasterization
(PR#512)
o GSoC 2020: Added Bresenham's algorithm for line rasterization (PR#
512)
o GSoC 2021: Added rotation of image by arbitrary angle around its
center (PR#565)

o Added for_each_pixel overload for any_image (PR#648)
o Added C++17 polymorphic memory resource typedefs for image class (
PR#529)
+ Changed
o BREAKING: The required minimum C++ version is changed from from
C++11 to C++14. Currently, large parts of GIL still compile with a
C++11 compiler. However, there is no guarantee that it stays that
way, and any compilers that do not support at least C++14 are
considered unsupported as of now.
o BREAKING: any_color_converted_view() is deprecated and will be
removed in the next release. Use color_converted_view() instead,
which provides the same feature.

removed in the next release. Use variant2::visit instead, which
provides the same feature. (PR#656)
o Moved numeric extension to core (PR#573)
o Added support for C++17's <filesystem> (PR#636) The availability of
the std::filesystem is detected automatically, unless the
BOOST_GIL_IO_USE_BOOST_FILESYSTEM macro is defined that forces the
preference of the Boost.Filesystem.
o Renamed pixel_multiply_t to pixel_multiplies_t and pixel_divide_t
to pixel_divides_t (PR#655)
o Renamed io/dynamic_io_new.hpp to io/detail/dynamic.hpp (PR#653)
o Moved function construct_matched into boost::gil::detail namespace
as it was only used by other implementation details (PR#653)
o Made packed_pixel trivially copyable and assignable (PR#679)
o Replace deprecated libtiff v4.3 typedefs with C99 fixed-size
integers (PR#685)

pixel elements (PR#542)
o Fixed returning reference to local temporary object in
subchroma_image_view (PR#556)

o Fixed any_image_view<>::const_t (PR#526)
o Fixed C++20 incompatibilities in I/O extensions (PR#617)
o Ensured all examples build without errors (PR#628)
o Fixed convolve_2d for images with float32_t channel model (PR#577)
o Fixed for_each_pixel for non-1d iterable views (PR#621)
o Fixed: is_equal_to_sixteen in PNG I/O was less-than test (PR#650)
o Re-allow devicen_t with two components (PR#654) It was
unintentionally removed in Boost 1.72
o Fixed memory leak in image class for empty dimensions (PR#649)

axes of zero size (physical or logical) under certain conditions
+ Removed previously deprecated API
o class accumulators::thread_safe: use accumulators::count<T, true>
o Methods accumulators::sum::large and accumulators::sum::small: use
accumulators::sum::large_part and accumulators::sum::small_part
o Type alias algorithm::reduce_option: use algorithm::reduce_command
o Template function axis::traits::static_options: use axis::traits::
get_options
o Template function axis::traits::static_is_inclusive: use axis::
traits::is_inclusive
o Type alias indexed::range_iterator: use indexed::iterator
o Type alias indexed::accessor::reference: use indexed::accessor::
const_reference
* Iterator:
+ For C++11 and later, added support for perfect forwarding of values
written to function_output_iterator. (PR#73)
+ Added protection against writing to function_output_iterator a result
of dereferencing another function_output_iterator.
* JSON:
+ Added non-const value::at overloads.
+ Added the ability to manually choose endianness of the platform.
+ Added string::subview() overload.
+ Fixed segfault in array::erase(it).
+ Fixed low performance of serialize on libc++.
+ Fixed ambigious conversion to std::string_view on GCC 8.
+ Fixed parsing on big-endian platforms.
+ Fixed handling of comment after trailing comma.
* LEAF:
+ API breaking change: throw leaf::exception(....) now becomes
leaf::throw_exception(....)
+ Fixed a bug in support for a rare build configuration (exception
handling enabled, diagnostics disabled)
+ Using nullptr instead of 0 throughout
+ Fixed pedantic warnings
* Locale:
+ Deprecated support for C++03 and earlier, C++11 will be required in the
next release
+ Provide -sICU_LINK_LOCALE as a temporary replacement for -sICU_LINK
which is incompatible with Boost.Regex. -sICU_LINK_LOCALE and -
sICU_LINK are deprecated and will be replaced by ICU_*_NAME options to
be compatible with Boost.Regex

transforming empty strings
+ Fix some issues related to visibility of classes in shared libraries
(Unix only)
+ Fix compatibility with C++20 mode
+ Fix compatibility with BOOST_USE_WINDOWS_H
+ Fix build failures due to missing includes
+ Handle or suppress many warnings which makes the build log cleaner
* Log:
+ Bug fixes:
o Fixed binding incorrect local address in UDP socket-based
syslog_backend when IPv6 address is used for the syslog server. (#
181)
o Added a workaround for a bug in libstdc++ from gcc 11.2. When
max_size_decor was used on a formatting stream, std::codecvt::
do_length incorrectly accessed the input buffer and caused a buffer
overflow.
+ See changelog for more details.
* Math:
+ Deprecated C++11 support: from 2023 we will require C++14 as a minimum
standard. This will mean GCC-5 or MSVC-14.1 as a minimal requirement.
+ Add constexpr fma support, see 734.
+ Add support for the Chatterjee Correlation Coefficient, see 770.
+ Added support for the logarithm of the PDF for all the distributions.
+ Improve support for building with no exception or RTTI support.
+ Some minor bug fixes for [sub 1]F[sub 1] corner cases, see 778.
* Multiprecision:
+ Mark C++11 support as deprecated: from 2023 we will move to requiring
C++14 as a minimum standard level. That will drop support for GCC
versions prior to 5 and MSVC prior to 14.1.
+ Fix conflict between boost/cstdfloat.hpp and this library.
+ Clean up lots of gcc and clang warnings.
+ Fix input streaming of composite types (complex, interval rational)
where there is a trailing delimeter in the stream and no whitespace.
+ Fix constexpr integer square root where the input is 1, 2 or 3.
+ Add missing #include of <memory> to float128.hpp.
+ Correct 2-arg constructor for class number to prevent ambiguity in some
cases.
+ Correct and make more consistent behaviour of divide-by-zero in
gmp.hpp.
* Multi-index Containers:
+ Maintenance work.
* Nowide:
+ Major performance improvement for Bulk I/O with files
+ basic_filebuf: Fix wrong return value of sync when fflush failed
+ basic_filebuf: Fix possible undefined behavior in a corner case when
nothing was actually written but buffer is in "write" mode
+ basic_filebuf: Limit putback of characters (i.e. pbackfail) only
allowing putback of buffered characters (may be only 1 character)
* Optional:
+ Added specializations for std::hash<boost::optional<T>>. This is a
breaking change for programs that define such specializations
themselves. For more details see specs.
* STLInterfaces:
+ Fix #53: "missing 'typename' prior to dependent type name
'C::const_iterator'"
+ Fix #54: "Concept check fails on .data() of a view on contiguous
iterator_interface instantiations"
+ New additions to make it easy to write views and view adaptors that
work like, and interoperate with, the ones in the standard library:
o Add workalikes for C++23's std::bind_back() and std::
range_adaptor_closure for pre-C++23 code.
o Add templates closure and adaptor to make writing view adaptors
easier, following the examples in P2387.
* System:
+ When an error_code is converted to std::error_code and then back to
error_code, the original is now restored, if possible.
+ Reworked the conversion from error_category to std::error_category to
avoid the one-time allocation that shows up on leak checkers.
+ Added a constructor that allows replacing the source location of an
error_code, and a corresponding assign.
+ Added a converting constructor to result.
* Unordered: Major update:
+ Refactor internal implementation to be dramatically faster
+ Allow final Hasher and KeyEqual objects
+ Update documentation, adding benchmark graphs and notes on the new
internal data structures
* Utility:
+ In string_view/string_ref, fixed max_size returning incorrect value. (#
91)
+ Removed noexcept specifier from string_view::compare as it may throw on
some input arguments. (#94)
+ In string_view/string_ref, added support for calling substr with no
arguments. (#96)
+ Added string_view::contains methods that were introduced in C++23. (#93
)
+ In string_view, added asserts in remove_prefix/remove_suffix methods to
enforce the precondition that the prefix/suffix length does not exceed
the string view size. The previous (undocumented) behavior of silently
clamping the prefix/suffix length is deprecated and will be removed in
a future release. (#92)
* Wave: Fixed bugs:
+ #24: Line numbers wrong after conditional section
+ #160: one test fails with error C2660 and error C2440 under msvc /
permissive- mode
+ #161: BOOST_WAVE_THROW_NAME_CTX does not result in a context callback
and always throws
+ #162: When Boost headers are included in the preprocessed translation
unit, Wave fails in boost/integer.hpp(99)

+ Fixed experimental::coro's per-operation cancellation.
+ Fixed memory management in experimental::promise's type-erased
completion handlers.
+ Fixed move operator= implementation for ssl::stream.
+ Fixed any_io_executor implementation to work when both
BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT and
BOOST_ASIO_SEPARATE_COMPILATION are defined.
+ Fixed implementation of basic_socket::at_mark() when using the
sockatmark() system call.
+ Changed the recycling allocator to use the default alignment as the
minimum alignment for allocations.
+ Added a workaround for apparent coroutine codegen bug with Apple's
clang.
+ On Windows, changed the file support to open files using the same
sharing mode as fopen().
+ On Linux, fixed UNIX domain sockets implementation to correctly handle
EAGAIN.

through the executor in some circumstances.
+ Fixed various header inclusion issues.
+ Fixed various warnings.
+ A number of documentation enhancements, including:
o Added an overview of Asio's asynchronous model.

o Re-arranged and extended the Overview documentation to cover
recently added features.
+ Added a C++11 example showing file descriptor passing over local
sockets.
+ Added C++14 examples of wrapping callback-based APIs in asynchronous

* Assert:
+ source_location().file_name() and source_location().function_name() now
return "" instead of "(unknown)".
+ Added a source_location constructor from std::source_location.
+ Changed BOOST_CURRENT_LOCATION to more closely match the behavior of
std::source_location::current(), such as being usable at top level or
as a default function argument.
* Atomic:
+ Fixed compilation for Universal Windows Platform (UWP). (#54)
+ Added BOOST_ATOMIC_NO_DARWIN_ULOCK configuration macro. The macro
affects compilation on Darwin systems and disables ulock-based
implementation of waiting and notifying operations. This may be useful
to comply with Apple App Store requirements. (#55)

traits. This implementation supports C++03 and above. (Glen Fernandes)
+ Updated the allocator access traits to support most of the C++11
allocator model in C++03. (Glen Fernandes)
+ boost/iterator.hpp is deprecated and will be removed in a future
release. The header defines boost::iterator template, which is
equivalent to std::iterator in <iterator> header. However, since std::
iterator is itself deprecated in C++17, users are advised to remove
boost::iterator or std::iterator use from their code.
+ Added boost::core::verbose_terminate_handler, a utility function
intended to be passed to std::set_terminate that prints information
about the uncaught exception to stderr.
* Describe:

std::is_union<T>.
+ Added example of defining a fmtlib class formatter.
+ Added example of defining a fmtlib enum formatter.

+ v3: path::replace_extension now works in terms of v3 definition of path
::extension rather than v4.
+ Fixed compilation of path appending and concatenation operators with
arguments of types convertible to path or compatible string type. (#223
)
+ On POSIX systems that support fdopendir and O_NOFOLLOW and on Windows,
remove_all is now protected against CVE-2022-21658. The vulnerability
is a race condition that allows a third party process to replace a
directory that is being concurrently processed by remove_all with a
directory symlink and cause remove_all to follow the symlink and remove
files in the linked directory instead of removing the symlink itself. (
#224)
+ On Windows, in remove and remove_all implementation, use POSIX
semantics for file removal, when supported by the OS (Windows 10 1709
and later). When POSIX semantics is supported, the file name is removed
from the filesystem namespace as soon as the file is marked for
deletion, even if it is still open and in use. With legacy Windows
semantics, the file name remains present in the the filesystem
namespace until the last file handle to the file is closed, which
allows the file marked for deletion to be opened and prevents creating
new files with the same name. (#216)
+ On Windows, remove and remove_all now support deleting read-only
directories. Support for removing read-only non-directory files was
added previously.
+ On Windows, directory_iterator internal implementation has been
reworked to better utilize modern Windows APIs, which may improve
performance while handling symlinks.
+ On Windows, initialize internal WinAPI function pointers early, if
possible, to allow Boost.Filesystem operations to be invoked in global
constructors. This is only supported on MSVC, GCC, Clang and compatible
compilers.
+ On Windows, resize_file should no longer fail with an error if the file
to be resized is opened.
+ Disabled use of the statx syscall on Android prior to 11.0 (API version
30). The syscall is blacklisted by seccomp and causes process
termination in runtime. (#229)
+ Deprecated: boost/filesystem/string_file.hpp header is deprecated and
will be removed in a future release. The header is no longer included
by boost/filesystem.hpp by default. Users are advised to implement the
functionality themselves or migrate to other implementations.
+ Deprecated: Windows CE support is deprecated and will be removed in a
future release. Windows CE has been untested for many years and is
likely non-functional.

Diff to previous 1.31 (colored) to selected 1.7 (colored)
boost: updated to 1.76.0
Updated Libraries
Asio:
Added ip::scope_id_type type alias.
Added ip::port_type type alias.
Added std::hash specialisations for IP addresses.
Added std::hash specialisations for ip::basic_endpoint<>.
Refactored SFINAE usage to improve compile times.
Added friendship support to customisation points, and made most customisations private.
Changed any_io_executor to a "strong typedef"-style class.
Fixed experimental::as_single to work with handler hook deprecation.
Ensured pthread condition variable attributes are cleaned up on all platforms.
Clarified thread safety notes on sockets and descriptors.
Ensured errno is not overwritten if socket() fails on macOS/FreeBSD.
Fixed work tracking for io_context and thread_pool executors when move-assigned.
Ensured internal call_stack objects are accessed only from implementation files.
Fixed I/O object move-assignment to ensure the executor is left in a valid state.
Fixed detection of compiler support for defaulted template argument on functions with MSVC.
Prevented the blocking.always property from being used with strand<>, as it did not produce the correct semantics.
Removed deprecated file asio/impl/src.cpp.
Atomic:
Fixed compilation with MSVC for ARM.
Beast:
This update brings minor bug fixes and revamped CI reporting.
We'd love to know how you or your company use Beast, consider adding an entry to the Companies and Individuals Using Beast list.
See the full Release Notes for a complete list of changes.
Bind:
Add support for using the standard C++11 placeholders with boost::bind.
Update boost::apply to use variadic templates and perfect forwarding.
Container:
Added [[no-discard]] attribute in all containers to catch bugs related to unused return values.
Replaced default standard exception classes with Boost.Container own classes, reducing considerably the included files overhead. Example: in MSVC 19 boost/container/vector.hpp preprocessed file size reduces from 1,5MB to 930KB. If you still want to use standard exception classes, you can define BOOST_CONTAINER_USE_STD_EXCEPTIONS before using any Boost.Container class.
Fixed bugs/issues:
GitHub 102: "flat_map::insert ambiguous with initializer list & pairs that need to convert".
GitHub 139: "flat_map merge and iterators".
GitHub 141: "small_vector does not propagate no throw properties of move operation of contained type".
GitHub 164: "Compile error when using pmr::map with a std::pair; works when using a std::tuple".
GitHub 171: "deque::clear() uses undefined behaviour".
Core:
Add implicit conversion between compatible reference wrappers.
Add boost/core/cmath.hpp, a portable implementation of the floating point classification functions from <cmath>.
Add boost/core/bit.hpp, a portable implementation of the C++20 standard header <bit>.
Fix BOOST_TEST_EQ, BOOST_TEST_NE for character types under C++20.
Revise allocator access utilities (now support VS2013, and no workarounds use allocator_traits.)
DLL:
BREAKING CHANGE: boost::dll::import was renamed to boost::dll::import_symbol to avoid collision with C++20 import keyword.
Updated docs, including FAQ section.
Filesystem:
Updated compatibility with WASI platform.
Fixed an exception being thrown by path::remove_filename if the path is "////".
Fixed create_directories disregarding errors from file status query operations issued internally. This could result in incorrect error codes returned by create_directories.
GIL:
BREAKING: In next release, we are going to drop support for GCC 5. We will also change the required minimum C++ version from C++11 to C++14.
Intrusive:
Reduced compile-time dependencies:
linear_slist_algorithms use a simple node_ptr instead of std::pair on return.
list/slist use operator </operator == instead of std::equal_to/std::less.
Fixed GitHub 54: set.rbegin() looks like O(log(N))
Interprocess:
Added wchar_t API support for named resources in operating systems that offer native wide character API (e.g. Windows). The following classes were updated with wchar_t name support:
file_mapping
managed_mapped_file
managed_shared_memory
managed_windows_shared_memory
shared_memory_object
windows_shared_memory_object
file_lock
named_condition
named_condition_any
named_mutex
named_recursive_mutex
named_semaphore
named_sharable_mutex
named_upgradable_mutex
message_queue
Added BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION macro option to disable the use of generic emulation code for process shared synchronization primitives instead of native POSIX or Winapi functions.
Fixed bugs:
GitHub 76 ("Cygwin compilation errors").
GitHub 83 ("Add BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION option").
GitHub 92 ("bufferstream: Correct MSVC compilation warning").
GitHub 106 ("Use fallocate on truncate_file").
GitHub 120 ("segment_manager customization").
GitHub 122 ("Mark constructors/assignment/swap noexcept where possible").
GitHub 126 ("_ReadWriteBarrier is deprecated warning when compiling with clang-cl.exe").
JSON:
Security Report from Bishop Fox.
Refactored value_from implementation; user customizations are now always preferred over library-provided overloads.
Fix imprecise parsing for some floating point numbers.
Fix link errors in standalone mode, when used alongside Boost.
Fix Boost.Build builds on GCC 4.8.
LexicalCast:
Dropped dependency on Boost.Math
Fixes for the CI and coverage
Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record queue implementation used in the unbounded_fifo_queue policy of the asynchronous_sink frontend. The race could be detected by TSAN, but it was not a real problem on most current CPU architectures and compilers.
When copying a logger with a channel attribute (e.g. channel_logger), the channel attribute is now deep-copied from the original logger. This means that modifying the channel in the new logger will no longer affect the original logger.
Replaced the use of std::allocator<void> in template parameters with a new tag type boost::log::use_std_allocator to silence libc++ warnings about the former being deprecated in C++17 and later. The tag indicates that the instantiated template should be using a specialization of std::allocator internally to allocate dynamic memory, so the change has no functional effect.
Boost.Log no longer defines __MSVCRT_VERSION__ macro on MinGW and MinGW-w64. Defining this macro caused incompatibility with UCRT, which is available as an option in recent MinGW-w64.
See changelog for more details.
Math:
Breaking Change: C++03 support is now removed, a C++11 or later conformant compiler is now required to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics: enables parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision cases.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit (long long) exponents with multiprecision types.
Move:
Git Issue 35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring and code simplification makes C++11 an absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free environments.
Correct corner case in pow.
Correct exception type thrown to match docs in lsb/msb.
Allow moves and operators between related but different types (ie types with the same allocator).
Nowide:
Fix discarding of characters for text file streams when seek or sync functions are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has been closed
Fix potential invalid memory access when using a file stream that has been moved or swapped to where the source had a put-back character or was set to unbuffered mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary files and writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases announcing this upcoming change, this is the FIRST RELEASE of the v2.2 branch. This branch has a number of major breaking changes to the Outcome v2.1 which shipped in Boost 1.75 and earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome to not compile on that compiler.
If on C++ 20, we now use C++ 20 [[likely]] instead of compiler-specific markup to indicate when TRY has likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const basic_result|basic_outcome *) noexcept was not propagated over BOOST_OUTCOME_TRY, which causes things like stack backtraces captured at the point of construction of an errored result to get dropped at every TRY point. This has been fixed by adding an optional spare_storage to success_type<T> and failure_type<T>, as well as to auto success(T &&, ...) and auto failure(T &&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS defined. Thanks to Emil, maintainer of Boost.Exception, making a change for me, Boost.Outcome should now compile with C++ exceptions globally disabled. You won't be able to use boost::exception_ptr as it can't be included if C++ exceptions are globally disabled.
BREAKING CHANGE 244 It came as a shock to learn that BOOST_OUTCOME_TRY had been broken since the inception of this library for certain corner case code, which required a breaking change in how TRY works. See the changelog in the documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue was used as a default value of a named parameter of a function.
PFR:
Fixed reflection of types with missing const in SFINAE expressions in template constructor. Now reflection of aggregates with std::optional<std::chrono::duration<???>> fields works on any Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
Fixed numerous typos in docs
PolyCollection:
Worked around GCC bug affecting GCC versions 9.3-10.2.
Predef:
Version 1.13
Add ARCH_PPC_64 predef.
Fix ARCH_WORD_BITS* redefinition warnings/errors.
Add ARCH_E2K, Elbrus 2000, architecture from Konstantin Ivlev.
Fix not handling recent C++ version that go above 10.x version.
Version 1.12
Switch to using the endian.h header on OpenBSD. (Brad Smith)
Fix not handling recent versions of stdcxx that go above version 9.
Fix including sub-BSD OS headers directly causing redef warnings.
Add CI testing of direct inclusion of all headers.
Add CI testing on FreeBSD for clang and gcc.
Add WORD_BITS set of predefs to detect the architecture word size. Initial implementation inspired by submission from Mikhail Komarov.
Add CI testing for Cygwin 32 and 64.
PropertyTree:
Property Tree has a new maintainer.
Fix usage of deprecated Boost.Bind features.
Link to Wikipedia fixed.
Use BOOST_OVERRIDE to fix GCC warnings.
Add extensive CI testing.
Regex:
Regex is now header only except in C++03 mode.
Support for C++03 is now deprecated.
The library can now be used "standalone" without the rest of Boost being present.
Stacktrace:
Better support for pre-C++11 builds on clang.
Bigger warning for do not use boost::stacktrace::stacktrace in signal handlers.
TypeTraits:
Fix for Visual Studio managed code projects.
Variant2:
Improved generated code for the double buffered case.
Updated Tools
Build:
Includes release of B2 version 4.4.1.

+ Optional header-only, without linking to a library
* LEAF: A lightweight error-handling library for C++11, from Emil Dotchevski.
+ Small single-header format, no dependencies.
+ Designed for maximum efficiency ("happy" path and "sad" path).
+ No dynamic memory allocations, even with heavy payloads.

* Atomic:
+ Implemented SSE2 and SSE4.1 versions of address lookup algorithm, which
is used in the internal lock pool implementation. This may improve
performance of waiting and notifying operations in heavily contended
cases.
+ Fixed a possible compilation error on AArch64 targets caused by
incorrect instructions generated for bitwise (logical) operations with
immediate constants. (#41)
* Beast:
+ This update brings bug fixes and support for the
BOOST_ASIO_ENBALE_HANDLER_TRACKING compile flag from Boost.Asio:
+ We'd love to know how you or your company use Beast, consider adding an
entry to the Companies and Individuals Using Beast list.
+ See the full Release Notes for a complete list of changes.
* Container:
+ New devector container.
+ Fixed bugs/issues:
o #152 Tree-based containers have troubles with move-only types.
o #156 Compile error with vector.
o PR#157 Add missing include.
o #159: pmr::monotonic_buffer_resource crashes on large single
allocations.
o #160: Usage of uses_allocator needs a remove_cvref_t.
o #162: small_vector on MSVC x86 call-by-value crash.
o #161: polymorphic_allocator(memory_resource*) non-standard
extension causes headache.

members.
o PR#166: Fix encoding error in copyright headers.
o PR#167: error: the address of 'msg' will always evaluate as 'true'
warning with GCC 4.4.
o #169: flood of warnings building dlmalloc_ext_2_8_6.c on clang11.
* Endian:
+ endian_arithmetic no longer inherits from endian_buffer
+ When BOOST_ENDIAN_NO_CTORS is defined, the unaligned endian_buffer and
endian_arithmetic are C++03 PODs, to enable use of __attribute__((
packed))
* Filesystem:
+ New: Added creation_time operation, which allows to obtain file
creation time. (Inspired by PR#134)
+ The returned value of last_write_time(p, ec) operation in case of
failure has been changed to a minimal value representable by std::
time_t instead of -1.
+ The returned value of hard_link_count(p, ec) operation in case of
failure has been changed to static_cast<uintmax_t>(-1) instead of 0.
+ On POSIX systems, file_size will now indicate error code errc::
function_not_supported if the path resolves to a non-regular file.
Previously, errc::operation_not_permitted was reported.
+ On Linux, many operations now use statx system call internally, when
possible, which allows to reduce the amount of information queried from
the filesystem and potentially improve performance. The statx system
call was introduced in Linux kernel 4.11.
+ Removed const-qualification from return types of some path methods.
This could prevent move construction and move assignment at the call
site in some cases. (#160)
+ On OpenBSD 4.4 and newer, use statvfs system call to obtain filesystem
space information. (Inspired by PR#162)
+ On Windows, space now returns with an error if the provided path does
not idendify an existing file. (#167)
* GIL:
+ BREAKING: In next release, we are going to drop support for GCC 5. We
may also change the required minimum C++ version from C++11 to C++14.
* Histogram:
+ This update brings
o Bug-fixes for corner-cases
o Small documentation improvements
o Fixes for new warnings from latest compilers and when compiling
against the C++20 standard
+ See the full Release Notes for a complete list of changes.
* Interprocess:
+ Fixed bugs:
o #127: static assertion failure with boost interprocess 1.74 and
basic_managed_shared_memory.
* Intrusive:
+ Fixed bugs:
o PR#48: MSVC "assignment within conditional" warning fix.
o PR#49: Fix empty control statement warnings.
o #52: Invalid casting in BOOST_INTRUSIVE_BSR_INTRINSIC.
* Log:
+ Bug fixes:
o Corrected the file counter that would be used in text_file_backend
when generating the target file name (based on the pattern set by
set_target_file_name_pattern method) when the log file is rotated.
(#125)
o Replaced a volatile version counter in basic_sink_frontend with an
atomic. (#128)
o In the asynchronous_sink frontend, resolved a possible conflict
between flush and run methods, if run is called from a user's
thread instead of the internal dedicated thread spawned by the
frontend. (#131)
+ See changelog for more details.
* Move:
+ Fixed bugs:
o #30: (void) C-cast is a non-portable way of suppressing compiler
warnings.
* Mp11:
+ Added mp_pairwise_fold (suggested by Barry Revzin)
+ Removed mp_invoke (use mp_invoke_q)
* Optional:
+ boost::none is constexpr-declared.
+ Fixed issue #78.
* Outcome:
+ Announcements:
o After a year and three major Boost releases announcing this
upcoming change, this is the FINAL RELEASE of the v2.1 branch. From
Boost 1.76 onwards, the v2.2 branch becomes the default. This
branch has a number of major breaking changes to Outcome v2.1, see
the documentation for details.
+ Enhancements:
o The ADL discovered event hooks have been replaced with
policy-specified event hooks instead. This is due to brittleness
(where hooks would quietly self-disable if somebody changed
something), compiler bugs (a difference in compiler settings causes
the wrong hooks, or some but not all hooks, to get discovered), and
end user difficulty in using them at all. The policy-specified
event hooks can be told to default to ADL discovered hooks for
backwards compatibility: set OUTCOME_ENABLE_LEGACY_SUPPORT_FOR to
less than 220 to enable emulation.
o Improve configuring OUTCOME_GCC6_CONCEPT_BOOL. Older GCCs had
boolean based concepts syntax, whereas newer GCCs are standards
conforming. However the precise logic of when to use legacy and
conforming syntax was not well understood, which caused Outcome to
fail to compile depending on what options you pass to GCC. The new
logic always uses the legacy syntax if on GCC 8 or older, otherwise
we use conforming syntax if and only if GCC is in C++ 20 mode or
later. This hopefully will resolve the corner case build failures
on GCC.
+ Bug fixes:
o Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS defined.
Thanks to Emil, maintainer of Boost.Exception, making a change for
me, Boost.Outcome should now compile with C++ exceptions globally
disabled. You won't be able to use boost::exception_ptr as it can't
be included if C++ exceptions are globally disabled.
o #236 In the Coroutine support the final_suspend() was not noexcept,
despite being required to be so in the C++ 20 standard. This has
been fixed, but only if your compiler implements noop_coroutine.
Additionally, if noop_coroutine is available, we use the much more
efficient coroutine handle returning variant of await_suspend()
which should significantly improve codegen and context switching
performance.
* Polygon:
+ C++20 fixes for event_comparison_type, vertex_equality_predicate_type,
and voronoi_predicates. (Glen Fernandes)
* Preprocessor:
+ When variadic data is empty in C++20 mode with __VA_OPT__ support the
variadic size has been corrected to be 0. This also means that in this
C++20 mode it is now valid to convert to and from empty arrays and
lists and variadic data. The end-user can read the "C++20 Support For
Variadic Macros" part of the "variadic macros" topic for more
information about empty variadic data in the library.
+ The macro BOOST_PP_IS_STANDARD() has been added for identifying if the
currently used preprocessor is a C++ standard conforming preprocessor.
A number of preprocessors which generally work correctly with the
library but need various internal workarounds, including the currently
default VC++ preprocessor, are not considered C++ standard conforming
preprocessors. However most preprocessors, including among others gcc,
clang, and the new but currently non-default VC++ preprocessor in
VS2019, are C++ standard conforming preprocessors.
+ For C++ standard conforming preprocessors a number of the limits
defined in the config/limits.hpp can now be changed to higher amounts
for a TU. The end-user should read the "limitations" topic to
understand how and which limits can be changed.
+ For C++ standard conforming preprocessors, in order to allow the
maximum number of FOR and WHILE iterations, the beginning 'r' and 'd'
iteration numbers in the user-defined macros start at 1 and not 2, as
it did in previous releases. This could be a breaking change if these
iteration numbers are used in the user-defined macros ( they probably
would not be ), but the change was necessary to fix some arcane bugs
when dealing with numerical/logical operations with maximum numbers as
well to allow the user-defined macros to be called the correct possible
maximum number of times. For non-C++ conforming preprocessors, this
change was not made because those non-conforming C++ preprocessors
generally have limitations which disallow the maximum number of looping
constructs to be run, and it was felt not to introduce a possible
breaking change to those more fragile preprocessors would be better. It
was also felt that besides fixing some arcane preprocessor bugs and
providing the possible maximum number of user-defined macro
invocations, this change could be made because it has never been
documented what the starting 'r' and 'd' iteration numbers actually are
but only that these numbers are incremented for each iteration.
+ The library has been upgraded to assume variadic macro support for any
compiler working with the library. Ostensibly this means that the
library is now a C++11 on up library, yet most of the major compilers,
including gcc, clang, and VC++, also support variadic macros in C++98/
C++03 mode as long as strict compliance to C++98/C++03 is not turned on
when using one of those compilers.
* Rational:
+ Fix Rational operators to not break under new C++20 operator==
rewriting rules. (Glen Fernandes)
* Signals2:
+ Correct C++ allocator model support to fix compilation in C++20
standards mode. (Glen Fernandes)
* System:
+ The platform-specific headers windows_error.hpp, linux_error.hpp, and
cygwin_error.hpp emit deprecation messages and are slated for removal.
+ The old names for generic_category() and system_category() emit
deprecation messages and are slated for removal.
+ error_condition::failed is deprecated and is slated for removal.
operator bool() for error_condition has been reverted to its old
meaning of value() != 0. This is done for compatibility with std::
error_condition as the next release is expected to improve
interoperability with <system_error> even further. Note that this does
not affect error_code::failed, which is still alive and well.
+ The overload of error_condition::message that takes a buffer is
deprecated and is slated for removal, for the same reasons. Note that
this does not affect error_code::message.
* uBLAS:
+ Correct C++ allocator model support to fix compilation in C++20
standards mode. (Glen Fernandes and Conrad Poelman)
* VMD:
+ The VMD number parsing has been upgraded to support the ability for the
end-user to change the number limits in the Preprocessor library.
+ The macro BOOST_VMD_IS_GENERAL_IDENTIFIER has been added to support the
parsing of input that represents a preprocessor token which matches the
VMD identifier syntax, without having to register the identifier as a
specific identifier.
* Wave:
+ Added new C++20 tokens, including the spaceship operator <=>
+ Fixed bugs:
o #94: fix incorrect behavior of __LINE__ and __FILE__ under
rescanning
1.74.0
New Libraries
* STLInterfaces: A library of CRTP bases to ease the writing of STL views,
iterators, and sequence containers, from Zach Laine.
Updated Libraries
* Asio:
+ Added an implementation of the proposed standard executors (P0443r13,
P1348r0, and P1393r0).
+ Added support for the proposed standard executors to Asio's I/O
facilities.
o The supplied executors now meet the requirements for the proposed
standard executors. These classes also continue to meet the
existing requirements for the Networking TS model of executors.
o All I/O objects, asynchronous operations, and utilities will
interoperate with both new proposed standard executors, and with
existing Networking TS executors.
o The any_io_executor type alias has been introduced as the default
runtime-polymorphic executor for all I/O objects. This defaults to
the execution::any_executor<> template. If required for backward
compatibility, BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT can be defined
to use the old asio::executor polymorphic wrapper instead.
o Support for the existing Networking TS model of executors can be
disabled by defining BOOST_ASIO_NO_TS_EXECUTORS.
+ Added converting move construction and assignment to
basic_waitable_timer.
+ Enabled C++20 coroutine support when using gcc 10.
+ Added overloads of co_spawn that launch an awaitable.
+ Added a new constructor overload to use_awaitable_t's default executor
adapter, to enable conversion between executor types.
+ Added support for using detached_t as a default completion token, by
adding members as_default_on() and as_default_on_t<>.
+ Added a move constructor to ssl::stream<>.
+ Changed ssl::stream<> write operations to linearise gather-write buffer
sequences.
+ Added compile-time detection of the deprecated asio_handler_invoke,
asio_handler_allocate, and asio_handler_deallocate hooks, when
BOOST_ASIO_NO_DEPRECATED is defined.
+ Implemented a number of performance optimisations.
+ Added source location support to handler tracking.
+ Implemented various improvements to the handlerviz.pl tool.
+ Added the handlerlive.pl tool, which processes handler tracking output
to produce a list of "live" handlers.
+ Added the handlertree.pl tool, which filters handler tracking output to
include only those events in the tree that produced the nominated
handlers.
+ Added changes for clang-based Embarcadero C++ compilers.
+ Fixed a deadlock that can occur when multiple threads concurrently
initialise the Windows I/O completion port backend.
+ Fixed async_compose to work with copyable handlers when passed by
lvalue.
+ Fixed completion signature deduction in co_spawn.
+ Removed a spurious Executor base class from the executor_binder
implementation.
+ Various fixes and improvements in the documentation and examples.
+ Consult the Revision History for further details.
* Atomic:
+ Added missing const qualifiers to some operations in atomic_ref.
+ Added support for yield instruction on ARMv8-A. The instruction is used
internally in spin loops to reduce CPU power consumption.
+ Added support for C++20 waiting and notifying operations. The
implementation includes generic backend that involves the internal lock
pool, as well as specialized backends for Windows, Linux, FreeBSD,
DragonFly BSD and NetBSD. Atomic types provide a new method
has_native_wait_notify, a static boolean constant
always_has_native_wait_notify and a set of capability macros that allow
to detect if the implementation supports native waiting and notifying
operations for a given type.
+ Changed internal representation of atomic_flag to use 32-bit storage.
This allows for more efficient waiting and notifying operations on
atomic_flag on some platforms.
+ Added support for build-time configuration of the internal lock pool
size. The user can define the BOOST_ATOMIC_LOCK_POOL_SIZE_LOG2 macro to
specify binary logarithm of the size of the lock pool. The default
value is 8, meaning that the size of the lock pool is 256, up from 64
used in the previous release.
+ Added support for a new set of atomic types dedicated for inter-process
communication: ipc_atomic_flag, ipc_atomic and ipc_atomic_ref. Users
are recommended to port their code using non-IPC types for
inter-process communication to the new types. The new types provide the
same set of operations as their non-IPC counterparts, with the
following differences:
o Most operations have an added precondition that is_lock_free
returns true for the given atomic object. The library will issue a
compile time error if this precondition is known to be not
satisfied at compile time.
o All provided operations are address-free, meaning that the atomic
object (in case of ipc_atomic_ref - the referenced object) may be
located in process-shared memory or mapped into the same process at
multiple different addresses.
o The new has_native_wait_notify operation and
always_has_native_wait_notify constant indicate support for native
inter-process waiting and notifying operations. When that support
is not present, the operations are implemented with a busy loop,
which is less efficient, but still is address-free. A separate set
of capability macros is also provided to indicate this support.
+ Added new atomic_unsigned_lock_free and atomic_signed_lock_free types
introduced in C++20. The types indicate the atomic object type for an
unsigned or signed integer, respectively, that is lock-free and
preferably has native support for waiting and notifying operations.
+ Added new gcc assembler backends for ARMv8-A (for both AArch32 and
AArch64). The new backends are used to implement operations not
supported by compiler intrinsics (including 128-bit operations on
AArch64) and can also be used when compiler intrinsics are not
available. Both little and big endian targets are supported. AArch64
backend supports extensions defined in ARMv8.1 and ARMv8.3.
+ Added support for big endian targets in the legacy ARM backend based on
gcc assembler blocks (this backend is used on ARMv7 and older targets).
Previously, the backend assumed little endian memory layout, which is
significant for 64-bit operations.
+ Improved performance of seq_cst stores and thread fences on x86 by
using lock-prefixed instructions instead of mfence. This means that the
operations no longer affect non-temporal stores, which was also not
guaranteed before. Use specialized instructions and intrinsics to order
non-temporal memory accesses.
+ Fixed capability macros for 80-bit long double on x86 targets not
indicating lock-free operations even if 128-bit atomic operations were
available.
+ Fixed compilation of gcc asm blocks on Alpha targets.
+ In the gcc __sync* intrinsics backend, fixed that store and load
operations of large objects (larger than a pointer size) could be
non-atomic. The implementation currently assumes that small objects can
be stored with a single instruction atomically on all modern
architectures.
* Beast:
+ This update brings bug fixes and support for the following changes
changes in Boost.Asio:
+ Beast supports BOOST_ASIO_NO_DEPRECATED. Define this to help identify
areas of your Beast and Asio code which use deprecated Asio interfaces.
+ Beast also supports BOOST_ASIO_NO_TS_EXECUTORS. Define this to identify
uses of executors from the now potentially outdated Networking TS
+ Asio will use the Standard Executors model by default. You can prevent
this behaviour by defining BOOST_ASIO_USE_TS_EXECUTOR_AS_DEFAULT in
which the Networking TS model will be used by default. Setting this
flag does not prevent a program from using executors from the Standard
Executors model explicitly.
+ We'd love to know how you or your company use Beast, consider adding an
entry to the Companies and Individuals Using Beast list.
+ See the full Release Notes for a complete list of changes.
* Bimap:
+ Correct allocator usage (fixes C++20 compilation). (Glen Fernandes)
* Config:
+ Implement BOOST_NO_CXX11_OVERRIDE and BOOST_OVERRIDE. (Glen Fernandes)
* Core:
+ Implemented the allocator access utilities which provide a replacement
for allocator_traits with individual traits and functions for each
facility. They support the C++11 allocator model when possible and
provide a fallback for C++98 compatibility. These are now used in
Circular_Buffer, Wave, Lockfree, Heap, Smart_Ptr, Dynamic_Bitset,
Format, Bimap and more. (Glen Fernandes)
* DLL:
+ Multiple fixes for the library_info work on empty shared objects.
+ Compilation fixes for C++98 and C++11 modes (#28).
+ Fixes for smart_library manglings (thanks to XiaLiChao82 #37).
* Endian:
+ Enabled scoped enumeration types in endian_reverse.
+ Enabled bool, enum, float, double in endian_reverse_inplace.
+ Added an overload of endian_reverse_inplace for arrays.
* Filesystem:
+ Removed compile-time checks for support for symlinks and hardlink on
Windows. Instead, a runtime check is used. (PR#142)
+ Fixed handling of reparse points in canonical and read_symlink on
Windows. This also affects other algorithms that involve canonical and
read_symlink in their implementation. (PR#100, #85, #99, #123, #125)
+ Fixed that read_symlink on Windows could potentially fail or cause
failures elsewhere with a sharing violation error, if the same symlink
was opened concurrently. (#138)
+ Fixed that is_symlink(directory_entry) would always return false, even
if the directory entry actually referred to a symlink. (PR#148)
+ Added missing status inspection operation overloads for directory_entry
and error_code (e.g. is_directory(directory_entry, error_code&)).
Removed incorrect noexcept specifications for the overloads not taking
the error_code arguments.
+ copy_file implementation has been updated to perform checks on the
source and target files, as required by C++20 ([fs.op.copy.file]/4.1).
In particular, the operation will fail if the source or target file is
not a regular file or the source and target paths identify the same
file.
+ copy_file on POSIX systems will now also copy the source file
permissions to the target file, if the target file is overwritten.
+ New: Added copy_file implementations based on sendfile and
copy_file_range system calls on Linux, which may improve file copying
performance, especially on network filesystems.
+ Deprecated: The copy_option enumeration that is used with the copy_file
operation is deprecated. As a replacement, the new enum copy_options
(note the trailing 's') has been added. The new enum contains values
similar to the copy_options enum from C++20. The old enum values are
mapped onto the new enum. The old enum will be removed in a future
release.
+ New: Added copy_options::skip_existing option, which allows copy_file
operation to succeed without overwriting the target file, if it exists.
+ New: Added copy_options::update_existing option, which allows copy_file
operation to conditionally overwrite the target file, if it exists, if
its last write time is older than that of the replacement file.
+ New: copy_file now returns bool, which indicates whether the file was
copied.
+ New, breaking change: copy operation has been extended and reworked to
implement behavior specified in C++20 [fs.op.copy]. This includes
support for copy_options::recursive, copy_options::copy_symlinks,
copy_options::skip_symlinks, copy_options::directories_only,
copy_options::create_symlinks and copy_options::create_hard_links
options. The operation performs additional checks based on the
specified options. Applying copy to a directory with default
copy_options will now also copy files residing in that directory (but
not nested directories or files in those directories).
+ New: Added create_directory overload taking two paths. The second path
is a path to an existing directory, which is used as a source of
permission attributes to use in the directory to create.
+ Deprecated: copy_directory operation has been deprecated in favor of
the new create_directory overload. Note that the two operations have
reversed order of the path arguments.
+ equivalent on POSIX systems now returns the actual error code from the
OS if one of the paths does not resolve to a file. Previously the
function would return an error code of 1. (#141)
+ equivalent no longer considers file size and last modification time in
order to test whether the two paths refer to the same file. These
checks could result in a false negative if the file was modified during
the equivalent call.
+ New: Added absolute overloads taking error_code argument.
+ Operations that have current_path() as the default value of their
arguments and also have an error_code argument will use the
current_path(error_code& ec) overload to obtain the current path, so
that its failure is reported via the error_code argument instead of an
exception.
+ space now initializes the space_info structure members to -1 values on
error, as required by C++20 ([fs.op.space]/1).
+ space on Windows now accepts paths referring to arbitrary files, not
only directories. This is similar to POSIX systems and corresponds to
the operation description in C++20. (#73)
+ New: Added implementation of temp_directory_path for Windows CE. (PR#25
)
+ New: Improved compatibility with WASI platform. (PR#144)
+ New: Improved support for Embarcadero compilers. (PR#130)
+ New: Added implementations of unique_path operation based on getrandom
(Linux), arc4random_buf (OpenBSD/FreeBSD/CloudABI) and BCrypt (Windows)
system APIs.
+ Deprecated: Auto-linking against system libraries on Windows with
MSVC-compatible compilers is deprecated and will be removed in a future
release. This affects users linking against static library of
Boost.Filesystem. Users are advised to update their project build
systems to either use a shared library of Boost.Filesystem, or
explicitly specify the dependencies of Boost.Filesystem in the linker
command line. Users of shared library of Boost.Filesystem are not
affected.
* Flyweight:
+ Maintenance work.
* Format:
+ Correct allocator usage (fixes C++20 compilation). (Glen Fernandes)

+ Acknowledgements
o Samuel Debionne, Pranam Lashkari, Mateusz Loskot, Debabrata Mandal
* Heap:
+ Correct destruction of top node in skew_heap. (Glen Fernandes)
+ Correct and simplify allocator use. (Glen Fernandes)
* Integer:
+ Fixed compilation of gcd in C++20 mode with clang 10.
+ Improved support for Embarcadero compilers. (PR#21)
* Iterator:
+ boost/function_output_iterator.hpp header is now deprecated. Users
should replace its inclusion with boost/iterator/
function_output_iterator.hpp. (PR#51)
+ Improved support for Embarcadero compilers. (PR#55)
* LexicalCast:
+ Fixed warnings on missing override (thanks to EugeneZelenko #35, #34).
+ Fixes for the the Embarcadero compilers (thanks to Edward Diener).
* Log:
+ Bug fixes:
o The syslog sink backend now verifies the IP version of the local
and target addresses set by user. The addresses must have the same
IP version as was specified in the ip_version named parameter on
the sink backend construction (by default, IPv4 is assumed). When
an address is obtained as a result of host name resolution, only
addresses with matching IP version are considered. (#119)
+ New Features:
o Move constructors and assignment operators of various components
were marked noexcept.
o Added a new range_manip stream manipulator that can be used for
outputting elements of a range, optionally separated by a
delimiter.
o Added a new tuple_manip stream manipulator that can be used for
outputting elements of a tuple or any other heterogeneous sequence,
optionally separated by a delimiter.
o Added a new optional_manip stream manipulator that can be used for
outputting optionally present values.
+ See changelog for more details.
* Mp11:
+ Improved compilation performance of mp_with_index<N> for large N.
+ Added tuple_transform (contributed by Hans Dembinski.)
* Multi-index Containers:
+ Added node extraction and insertion following the analogous interface
of associative containers as introduced in C++17. This feature has also
been extended to non key-based indices, in contrast to C++ standard
library sequence containers, which do not provide such functionality.
+ Clarified documentation on read/write key extractors (issue #32).
+ Maintenance work.
* Nowide:
+ The library now requires a C++11-compliant compiler and stdlib
+ LFS: Add support for files > 2 GB where the underlying system supports
it
+ Generic UTF conversion functions are now available in the boost::nowide
::utf namespace
+ Add support for stat with UTF-8 paths
* Outcome:
+ Announcements:
o The v2.1 branch is expected to be retired end of 2020, with the
v2.2 branch becoming the default. You can use the future v2.2
branch now using better_optimisation. This branch has a number of
major breaking changes to Outcome v2.1, see the front page for
details.
+ Enhancements:
o BREAKING CHANGE void results and outcomes no longer default
construct types during explicit construction. Previously if you
explicitly constructed a result<T> from a non-errored result<void>,
it default constructed T. This was found to cause unhelpful
surprise, so it has been disabled.
o New macro OUTCOME_ENABLE_LEGACY_SUPPORT_FOR. The macro
OUTCOME_ENABLE_LEGACY_SUPPORT_FOR can be used to enable aliasing of
older naming and features to newer naming and features when using a
newer version of Outcome.
o Concepts now have snake case style naming instead of camel case
style. When Outcome was first implemented, it was thought that C++
20 concepts were going to have camel case style. This was changed
before the C++ 20 release, and Outcome's concepts have been renamed
similarly. This won't break any code in Outcome v2.1, as
compatibility aliases are provided. However code compiled against
Outcome v2.2 will need to be upgraded, unless
OUTCOME_ENABLE_LEGACY_SUPPORT_FOR is set to 210 or lower.
o Concepts now live in OUTCOME_V2_NAMESPACE::concepts namespace.
Previously concepts lived in the convert namespace, now they live
in their own namespace.
o New concepts basic_result<T> and basic_outcome<T> added. End users
were finding an unhelpful gap in between is_basic_result<T> and
value_or_error<T> where they wanted a concept that matched types
which were basic_result, but not exactly one of those. Concepts
filling that gap were added.
o Operation TRY works differently from Outcome v2.2 onwards. This is
a severely code breaking change which change the syntax of how one
uses OUTCOME_TRY(). A regular expression suitable for upgrading
code can be found in the list of changes between Outcome v2.1 and
v2.2.
+ Bug fixes:
o #224 The clang Apple ships in Xcode 11.4 (currently the latest) has
not been patched with the fixes to LLVM clang that fix noexcept(std
::is_constructible<T, void>) failing to compile which I originally
submitted years ago. So give up waiting on Apple to fix their
clang, add a workaround to Outcome.
o Spare storage could not be used from within no-value policy
classes. Due to an obvious brain fart when writing the code at the
time, the spare storage APIs had the wrong prototype which
prevented them working from within policy classes. Sorry.
* PolyCollection:
+ Fixed internal ambiguity problem between boost::type_erasure::any and
boost::any (issue #17).
+ Maintenance work.
* SmartPtr:
+ Added owner_equals to shared_ptr, weak_ptr, local_shared_ptr.
+ Added owner_hash_value to shared_ptr, weak_ptr.
+ Added owner_equal_to, owner_hash.
+ Added std::hash specializations for shared_ptr, local_shared_ptr.
+ Added boost::hash support to, and std::hash, std::equal_to
specializations for, weak_ptr.
* Stacktrace:
+ Fixed a build error when compiled with -fno-exceptions (thanks to
Jeremiah Rodriguez #91).
* System:
+ operator bool() now returns failed() instead of value() != 0.
* Type_Traits:
+ Implemented conjunction, disjunction, negation, is_trivially_copyable,
is_scoped_enum, and is_unscoped_enum. (Glen Fernandes)
* Variant:
+ Fixed warnings on missing override (thanks to EugeneZelenko #78).
+ Fixes for the the Embarcadero compilers (thanks to Edward Diener #79).
+ Updated header locations to avoid warnings about using deprecated
headers (thanks to Andrey Semashev #80)
* Variant2:
+ Added support for derived types in visit.
+ Improved compilation performance for many (hundreds of) alternatives.
+ Added support for visit<R>.
* Wave:
+ Implement C++20 features for variadics, including __VA_OPT__ (PR#75)
+ Implement __has_include (PR#102)
+ Introduce new sample: check_macro_naming, useful with Boost itself (PR#
97)
+ Fix compilation issue caused by std::allocator member removal in C++20
(PR#72)
+ Repair Xpressive lexer and token_statistics sample (PR#79)
+ Repair lexertl lexer (PR#78)
+ Ensure hooks are run on predefined macros as well (PR#87)
+ Various minor bug fixes
+ C++98/03 support is now deprecated and will be removed in 1.77
* YAP:
+ Fixed compilation errors for placeholders; they now work in the general
case, and in particular work with yap::print().
+ constexpr all the YAP.
+ Fix printing of correct value category in yap::print().
+ Doc clarification.
Updated Tools
* Boostbook:
+ Change encoding of generated documentation from US-ASCII to UTF-8.

Diff to previous 1.29 (colored) to selected 1.7 (colored)
boost: updated to 1.73.0 1.73.0: Known Issues ------------ These are patches from library authors which were found too late to be fixed in the release. Be careful as they have not been through the normal testing process. New Libraries ------------- Nowide: Standard library functions with UTF-8 API on Windows, from Artyom Beilis. StaticString: A dynamically resizable string of characters with compile-time fixed capacity and contiguous embedded storage, from Vinnie Falco and Krystian Stasiowski Updated Libraries ----------------- Align: * Update aligned_alloc to support older mingw32. Any: * Speedup compilation by not including <algorithm>. * Maintenance work, including CI hardening. Asio: * Fixed compatibility with C++20 concept syntax. * Marked the POSIX descriptor classes' move constructors as noexcept. * Added the ssl::host_name_verification class, which is a drop-in replacement for ssl::rfc2818_verification. The ssl::rfc2818_verification class has been marked as deprecated. As a consequence of this change, SSL support now depends on functions that were introduced in OpenSSL 1.0.2. * Added an ssl::context constructor to take ownership of a native handle. * Changed C++ language version detection with gcc to use __cplusplus macro. * Fixed a work counting issue in the asynchronous resolve operation for endpoints. * Fixed the strand<> converting constructors and assignment operators. * Ensured that resolvers are restarted correctly after a fork. * Fixed compatibility with the current NetBSD release. * Removed spurious handler requirement checks in some async_read overloads. * Changed the ssl::context class to propagate non-EOF errors from the add_certificate_authority function. * Fixed a Windows-specific thread_pool destructor hang that occurred when the pool had an associated I/O object. * Changed the select reactor to recreate the "self pipe trick" sockets on error. This addresses an issue on some versions of Windows, where these sockets are discconected after a system sleep. * Fixed a compile error in the buffered streams due to the lack of reference collapsing in C++98. * Changed the priority_scheduler example to demonstrate calls to shutdown() and destroy(). * Removed some unnecessary null pointer checks. * Changed Windows platform detection to recognise TV titles as Windows apps. * Added some emscripten compatibility patches. * Fixed a compile error in the use_awaitable_t::as_default_on function. * Changed all uses of the boost.bind placeholders to use the boost::placeholders namespace. * Fixed a potential compile error in the async_compose implementation due to incorrect overload selection. * Suppressed some non-virtual destructor warnings. * Various documentation fixes and improvements. Assert: * Added source_location. Atomic: * Implemented C++20 atomic_ref. See docs and especially the caveats section. * Implemented atomic_flag::test operation, which was introduced in C++20. * atomic<T> should now take into account alignment requirements of T, which makes a difference if those requirements are higher than that of the internal storage of atomic. * Added static asserts enforcing the requirements on the value type T used with atomic and atomic_ref. This should prohibit invalid types from being used as atomics. * Improved internal lock pool implementation. The pool is larger, and lock selection accounts for atomic object alignment, which should reduce the potential of thread contention. * Fixed incorrect x86 code generated for bit_test_and_* operations on 8 and 16-bit arguments. Other architectures are not affected. * Fixed a possible unaligned memory access in compare_exchange_* operations, if alignment requirements of value_type are less than that of the internal storage of atomic. * boost/atomic/atomic.hpp no longer includes boost/atomic/atomic_flag.hpp and boost/atomic/fences.hpp and only defines the boost::atomic class template and related typedefs. Include the other headers explicitly or use boost/atomic.hpp to include all parts of Boost.Atomic. * The atomic<T>::storage() accessor and associated atomic<T>::storage_type type are deprecated. Instead, users are advised to use atomic<T>::value() and atomic<T>::value_type, respectively. Users can define BOOST_ATOMIC_SILENCE_STORAGE_DEPRECATION to disable deprecation warnings for the time of transition. The deprecated pieces will be removed in a future release. * Removed support for BOOST_ATOMIC_DETAIL_HIGHLIGHT_OP_AND_TEST. This macro was used as a helper for transition to the updated returned values of *_and_test operations in Boost.Atomic 1.67, which was released 2 years before 1.73. Beast: * This is a maintenance update. * Nested mutable_data_type in Beast dynamic buffers is deprecated. * We'd love to know how you or your company use Beast, consider adding an entry to the Companies and Individuals Using Beast list. * See the full Release Notes for a complete list of changes. Context: * IBM Z: Fix fcontext routines * mips64/n64: .align 3 * Use OSPLAT MIPS32/MIPS64 to set different ABI * Fix non-PIC in RISC-V assembly Conversion: * Added boost::polymorphic_downcast for references (thanks to Julien Delacroix for the patch). * Significant docs update. date_time: * Support constexpr in c++14 and above * Make date_time all inline. Users no longer need to link the library for any functions. Library remains for build compatibility. * Deprecate support for legacy io and USE_DATE_TIME_PRE_1_33_FACET_IO macro * Misc documentation updates and bugfixes. DLL: * Fixes and tests for demangling in boost::dll::smart_library * Make UB sanitizers happy with boost::dll::load_mode::type * Ceased dependence on MPL improving compile times * Clang and ICC on Windows fixes and CI support for those platforms * Maintenance work, including CI hardening and tests improving. Dynamic Bitset: * Fixed a portability issue in the definition of the maximum block limit. Flyweight: * Maintenance work. Geometry: * Improvements - Missing input combinations in intersection() and introduction of tupled-output. - Added d3::point_xyz geometry model (thanks to Digvijay Janartha). * Solved issues - Incorrect definition of EPSG:3785. * Bugfixes - R-tree exception-safety improvement. - Andoyer inverse formula fixed for close points. - Fixed dangling reference in distance algorithm. * Deprecation - Support for C++03 has been deprecated and Geometry will require C++14 from Boost 1.75 onwards. GIL: * Added move constructor and move assignment operator to image class * New member function size() in any_image_view class * Replace Boost.Test with Boost.LightweightTest as the only test framework used in GIL. This also restructured the test/extension/io/ sub-tree and targets in related Jamfile-s. * Removed remaining uses of Boost.MPL * Renamed all macros using BOOST_GIL_ prefix * Renamed all CMake configuration options using BOOST_GIL_ prefix * Removed extension/dynamic_image/reduce.hpp as unused and possibly unfinished. An implementation attempt of techniques described in the paper Efficient Run-Time Dispatching in Generic Programming with Minimal Code Bloat by Lubomir Bourdev, Jaakko Jarvi. * Removed direct dependency on Boost.MPL, Boost.System and Boost.Test. * Started removing public macros for compile-time configuration of I/O extension tests, i.e. BOOST_GIL_IO_TEST_ALLOW_READING_IMAGES and BOOST_GIL_IO_TEST_ALLOW_WRITING_IMAGES. Instead, if a test target is built, it builds all its test cases unconditionally. * Avoid longjmp interaction during destruction of I/O extension objects. * Fixed missing alignment default value in constructor of image class. * Fixed segmentation fault when reading corrupted PNG file. * Fixed illegal initialization of return values in the old IOv1 interface of I/O extension. Histogram: * Added crop command to reduce algorithm * slice command in reduce now works on category axis * Added count accumulator, can be used to add arbitrary metadata to each cell * sum algorithm gained a new argument to optionally sum only over inner bins * Several fixes for bugs in corner cases * Enhanced documentation icl: * Remove references to date_time compiled library. * Fix forward decl lower and upper less equal. * Misc bugfixes. IO: * Made all the IOS state saver classes non-copyable. (Glen Fernandes) * Correctly handle error upon first read from the input stream when reading a quoted string. (Glen Fernandes) * Implemented ostream_joiner for delimiter based joining. (Glen Fernandes) * Relocated ostream_string from the Utility library to the IO library as ostream_put. * Correctly handle stream width and fill in quoted output. (Glen Fernandes) * Optimize quoted output to write directly to the stream buffer. (Glen Fernandes) * Glen Fernandes became the maintainer of the IO library. LexicalCast: * Maintenance work, including CI hardening and better workarounds for broken standard libraries Log: * Default sink used in trivial logging, when no sinks are registered in the logging core, now automatically flushes output after each log record * core::flush now performs a flush on the default sink used for trivial logging, when no sinks are registered. * Added a workaround for some syslog API implementations (e.g. glibc), which do not save the application identification string in openlog call. Such implementations could access already freed memory on each syslog call, resulting in undefined behavior. * Fixed that log file rotation on a specific day of month (e.g. rotation_at_time_point(boost::gregorian::greg_day(1))) could be silently ignored and not happen. * Fixed that text_file_backend::rotate_file could throw if there were no log records written yet and target file name pattern was set. * Ported various components of the library to std::allocator_traits to improve compatibility with C++20 allocators. * Fixed compilation errors when building in MSYS2 Cygwin environment. Math: IMPORTANT: C++03 support is now deprecated and will be removed from March 2021. * Added Cubic Hermite Interpolation. * Added Modified Akima Interpolation. * Added PCHIP Interpolation. * Added Quintic Hermite Interpolation. * Added entropy to numerous distributions. * Allow trivial quadrature case where the two end points are equal, and in addition allow bounds to be interchanged. * Fix exp_sinh quadrature to work with complex types over a non-native range. * Fix miscellaneous compiler warnings in factorial.hpp. * Use std::chrono rather than boost::chrono in timed pFq calculations. * Remove much of the old boost::mpl dependencies to improve constexpr support. Mp11: * Added mp_unique_if (contributed by Kris Jusiak) * Added mp_flatten * Added mp_rotate_left, mp_rotate_right (contributed by Duncan Barber) * Added mp_compose * Added mp_power_set * Added mp_partial_sum * Added mp_iterate Multi-index Containers: * multi_index_container is now AllocatorAware. * Swapping of internal KeyFromValue, Compare, Hash and Pred objects now selects the appropriate swap function between std::swap and ADL candidates, in accordance with standard specifications in [swappable.requirements] * Provided some internal copy constructors and assignment operators whose default implicit definition is deprecated in C++11 onwards ([depr.impldec]), which was warned about on some compilers. Multiprecision: * IMPORTANT: Mark C++03 support as deprecated and due for removal in 2021. * Big update to cpp_int adds faster Karatsuba and Coomba multiplication routines. * Fix conversion of gmp_rational to long double and __float128 * Fix up libtommath support to function with the latest libtom releases. * Fix up some incompatibilities with the latest Intel C++ compiler. * Fix up constexpr arithmetic support for latest MSVC release. Outcome: * Performance of Outcome-based code compiled by clang has been greatly improved. The previous implementation of Outcome's status bitfield confused clang's optimiser, which caused low quality codegen. Unlike most codegen issues, this was noticeably in empirical benchmarks of real world code, as was shown by P1886 Error speed benchmarking. * The safe part of the better_optimisation Outcome v2.2.0 future branch was merged to Outcome v2.1.3 which includes a new status bitfield implementation. This appears to not confuse clang's optimiser, and clang 9 produces code which routinely beats GCC 9's code for various canned use cases. * Installability is now CI tested per commit. Due to installability of standalone Outcome (e.g. make install) breaking itself rather more frequently than is ideal, installability is now tested on CI per commit. * Newer Concepts implementing compilers were unhappy with the early check for destructibility of T and E, so removed template constraints, falling back to static assert which runs later in the type instantiation sequence. * A false positive undefined behaviour sanitiser failure in some use cases of Experimental Outcome was worked around to avoid the failure message. PolyCollection: * Suppressed a potential redundant move warning in boost::poly_collection::for_each. * Fixed a bug by which elements were copied rather than moved in allocator-extended move construction and move assigment between collections with non-propagating, unequal allocators. * Allocator-extended move construction no longer decays to allocator-extended copy construction for the legacy version of libstdc++-v3 shipped with GCC 4.8 (which can also be used by Clang). Stacktrace: * Added documentation on distribution of PDBs * Fixed msvc-9 build * Maintenance work, including test fixes fixing typos CI improvements and hardening, inspect tool fixes. Test: * Boost.test v3.13 see the Changes log for more details. * New feature: It is now possible to combine tolerance indication, user message and collection comparison modifier in a single BOOST_TEST expression. See change logs for more details. ThrowException: * Added an overload of throw_exception that takes a boost::source_location object. * NOTE: Projects using BOOST_THROW_EXCEPTION with exceptions disabled will need to add a definition of this new overload. TTI: * Added introspection of function templates for more recent C++ compilers versions from gcc and vc++. as well as all versions of clang. Older versions of vc++ before 14.0 and gcc prior to 4.8 may fail. * Added specific introspection for elements of struct/class, enum, and union types, which can be used for more fine-grained introspection than the general 'type' introspection. TypeIndex: * Maintenance work, including CI integration with inspect tool. Utility: * The ostream_string facility has moved from the Utility library to the IO library as ostream_put. Variant: * Removed unused includes * Fixed zero-as-null-pointer-constat warnings * Maintenance work, including typo fixes. Variant2: * Added support for std::hash, boost::hash. * variant<T...> is now trivial when all types in T... are trivial. This improves performance by enabling it to be passed to, and returned from, functions in registers. WinAPI: * Headers in boost/detail/winapi are deprecated and will be removed in a future release. * Boost.WinAPI headers no longer include winerror.h. Include boost/winapi/error_codes.hpp to get Windows error codes.

Container:
Fixed bugs:
GitHub #47: "added alignment specification for small_vector".
GitHub #88: "Implement C++17 MoveAssignable requirements for self-move assignments".
GitHub #107: "Alignment ignored in resource_adaptor".
GitHub #109: "Get rid of integer overflow in copy_move_algo.hpp (-fsanitize=integer)".
GitHub #110: "Avoid gcc 9 deprecated copy warnings in new_allocator.hpp".
GitHub #112: "vector::resize() compilation error with msvc-10..12: data is not a member of boost::detail::aligned_storage".
GitHub #114: "Fix small_vector noexcept specification".

Context:
Add support for RISC-V LP64D
#72: Fix ABI violation on ppc64 ELFv2
#99: cleanup of stack if creating ucontext fails
Conversion:
Maintenance work.
Core:
Added functions alloc_construct, alloc_construct_n, alloc_destroy, and alloc_destroy_n in <boost/core/alloc_construct.hpp> for allocator aware and exception safe construction and destruction of objects and arrays. (Glen Fernandes)
Added constexpr functions first_scalar in <boost/core/first_scalar.hpp> for obtaining a pointer to the first scalar element of an array. Given a pointer of type T* they return a pointer of type remove_all_extents_t<T>*. (Glen Fernandes)
Added class template noinit_adaptor in <boost/core/noinit_adaptor.hpp> which is an allocator adaptor that converts any allocator into one whose construct(ptr) performs default initialization via placement new, and whose destroy(ptr) invokes the value_type destructor directly. (Glen Fernandes)
Added class template default_allocator in <boost/core/default_allocator.hpp>, which can serve as a minimal default allocator that has interface similar to C++20 std::allocator, supports configurations with disabled exceptions and does not have std as an associated namespace. The allocator uses operator new and operator delete for allocation. (Glen Fernandes)
In <boost/core/uncaught_exceptions.hpp> header, added workarounds for better compatibility with QNX SDP 7.0 when libc++/libc++abi libraries are used. (Andrey Semashev, #59)
The <boost/detail/sp_typeinfo.hpp> header is now marked as deprecated and will be removed in a future release. <boost/core/typeinfo.hpp> should be used instead. (Peter Dimov)
Dynamic Bitset:
Enabled hardware-assisted popcount on MSVC (#38).
Added support for boost::hash and std::hash (#45).
Support copy-initialization with default constructor (#48).
Endian:
Clarified requirements on the value type template parameter
Added support for float and double
Added endian_load, endian_store
Updated endian_reverse to correctly support all non-bool integral types
Moved deprecated names to the deprecated header endian.hpp
Fiber:
documentation for shared_work updated
Filesystem:
Fixed incorrect error_code returned from directory iterator increment when readdir_r is used.
For path, fixed rvalue-aware operator/ return type to return an rvalue instead of rvalue reference. This fixes leaving a dangling reference in the user's code if the result of operator/ is bound to a const reference. (#110)
Fixes for better compatibility with Windows CE. (#24)
Added minimal support for CMake. (#106)
Flyweight:
Maintenance work.
Histogram:
New features:
Support for thread-safe storages and new thread-safe accumulators
Support for compiling without exceptions/RTTI (increases performance by 10-20 %) (with Glen Fernandes)
Performance improvements for 1D and 2D histograms
boost::histogram::indexed now returns forward iterator range instead of input iterator range
boost::histogram::indexed_range::accessor is now non-copyable and acts like reference to cell value, making more algorithms from the C++ stdlib work
boost::histogram::algorithm::reduce with new slice option and option fusion
boost::histogram::algorithm::project accepts runtime indices for static histograms
Bug Fixes:
boost::histogram::algorithm::reduce also works on histograms that have some axis types without reduction support
boost::histogram::axis::traits::update now works correctly for boost::histogram::axis::variant
Other:
100 % test coverage
Reduced internal Boost dependencies
Improved documentation and examples
Guaranteed no-throw moves for all builtin axis types
Compile cleanly at higher warning levels
See changelog for more details.
IoStreams:
Fixed processing of multi-stream files (#87).
Added support for multi-threaded LZMA (#95).
Interprocess:
GitHub #85 ("warning: Implicit conversion loses integer precision").
GitHub #86 ("warning: Possible misuse of comma operator").
Intrusive:
GitHub #42: Documentation does not describe treap priority_of_value changes
GitHub #43: Fix tests with BOOST_INTRUSIVE_VARIADIC_TEMPLATES enabled
GitHub #45: Disable variadic templates for MSVC-12 to avoid ICEs
LexicalCast:
Added tests for boost::filesystem::path conversions #25.
Maintenance work, including #28.
Log:
New features:
Improved support for C++17 std::string_view in basic_formatting_ostream. The string view can now participate in character code conversion on output.
Added auto_newline formatter and stream manipulator. It can be used to ensure that formatted output always ends with a newline while avoiding duplicate newlines.
In the output stream, text file and text multi-file sink backends added support for configuring behavior with regard to appending a trailing newline to every formatted log record. Use auto_newline_mode named parameter of the backend constructor or call the set_auto_newline_mode method on the sink backend.
Note: The default behavior with regard to trailing newlines added by sink backends has changed slightly compared to the previous Boost.Log releases. The backends will now only add a trailing newline if there isn't one in the formatted log message string already. In previous releases a newline was added unconditionally.
Added support for passing arbitrary function objects in the filter and format named parameters to sink constructors and convenience functions for initializing sinks. For example, it is now possible to specify C++11 lambda functions directly in these parameters. (#63)
In the default filter and formatter factories used in filter and formatter parsers, added support for severity level attribute values of type boost::log::trivial::severity_level. For filters, the support is limited to attributes with "Severity" name.
Bug fixes:
Fixed incorrect parsing of components of the rotated file names while scanning for files in the text file sink backend. If the file name pattern ended with a placeholder (for example, a file counter), the scan_for_files method would not find files matching that pattern in the target storage, leaving them unmanaged. In particular, such files would not be deleted to free target storage. (#78)
Updated basic_formatting_ostream and basic_record_ostream to make it possible to overload stream output operators for pointers to user-defined types. User-defined operator<< overloads taking std::basic_ostream and a pointer argument should now be picked up by the compiler when the pointer is being written to one of Boost.Log streams. (#84)
See changelog for more details.
Math:
New features:
Catmull-Rom interpolator now works in C++11
Cardinal quadratic B-spline interpolation
Domain of elliptic integrals extended
sin_pi and cos_pi performance improvements
Forward-mode automatic differentiation
Vector valued barycentric rational interpolation
Ooura's method for evaluation of Fourier integrals
Bug fixes:
Multiple compatibility issues with Multiprecision fixed
Lambert-W fixed on a rare architecture
Metaparse:
New features:
In C++11 variadic template support for the following: sequence, one_of_c, one_of, repeated_one_of, repeated_one_of1, one_char_except_c, one_char_except.
Bug fixes:
BOOST_METAPARSE_STRING does not use out of range character values as template arguments.
any_of_c<> does not create empty array in C++14.
Move:
Git Issue #26: "Invalid iterator increment/decrement in the last iteration of adaptive_sort_combine_blocks".
Multi Array:
Simplify allocator support by using new alloc_construct_n and alloc_destroy_n facilities from Core. (Glen Fernandes)
Multi-index Containers:
Added variants of const_mem_fun and mem_fun for differently qualified member functions (issue #24).
Terse key specification syntax now correctly handles noexcept-specified member functions (issue #24).
Outcome:
Enhancements:
#184 As per request from Boost release managers, relocated version.hpp and revision.hpp into detail, and added the Boost licence boilerplate to the top of every source file which was missing one (I think). Also took the opportunity to run the licence restamping script over all Outcome, so copyright dates are now up to date.
#185 Add FAQ item explaining issue #185, and why we will do nothing to fix it right now.
#189 Refactored the OUTCOME_TRY implementation to use more clarified customisation points capable of accepting very foreign inputs. Removed the std::experimental::expected<T, E> specialisations, as those are no longer necessary. Fixed the documentation for the customisation points which previously claimed that they are ADL discovered, which they are not. Added a recipe describing how to add in support for foreign input types.
#183 Added a separate motivation/plug_error_code specifically for Boost.
Bug fixes:
OUTCOME_VERSION_MINOR hadn't been updated to 1.
#181 Fix issue #181 where Outcome didn't actually implement the strong swap guarantee, despite being documented as doing so.
#190 Fix issue #190 in Boost edition where unit test suite was not runnable from the Boost release distro.
#182 Fix issue #182 where trait::is_exception_ptr_available<T> was always true, thus causing much weirdness, like not printing diagnostics and trying to feed everything to make_exception_ptr().
#192 Fix issue #192 where the std::basic_outcome_failure_exception_from_error() was being defined twice for translation units which combine standalone and Boost Outcome's.
Parameter:
Upgraded keyword generation macro BOOST_PARAMETER_TEMPLATE_KEYWORD (#15).
Moved keyword generation macro BOOST_PARAMETER_NESTED_KEYWORD from Accumulators to this library (#28).
Added support for std::reference_wrapper and std::ref() (#16).
Moved boost::parameter::required, boost::parameter::optional, and boost::parameter::deduced metafunction definitions to their own header files in directory boost/parameter (#18).
Added support for Boost.Parameter-enabled function call operators (#20).
Added support for parameter category qualifiers "forward", "consume", and "move_from" (current qualifiers are "in", "out", and "in_out") (#21) (#23) based on http://www.modernescpp.com/index.php/c-core-guidelines-how-to-pass-function-parameters. Added new usage syntax BOOST_PARAMETER_NAME((object-name), namespace-name) qualifier(tag-name)) and BOOST_PARAMETER_NAME(qualifier(name)). (Existing code that uses qualifiers directly and correctly with BOOST_PARAMETER_FUNCTION and other code generation macros should remain unaffected for now, so no breaking changes.) The reason for the change in usage is to enable applying of parameter category constraints to Boost.Parameter-enabled functions and constructors invoked through argument composition. (Otherwise, it is currently possible to use argument composition to bypass parameter category constraints applied in BOOST_PARAMETER_FUNCTION et. al.)
Added support for perfect forwarding (#23) (#26), so that parameter::parameters::operator() can accept non-const rvalues. As a positive side effect, Boost.Parameter-enabled functions and constructors are no longer bound by BOOST_PARAMETER_MAX_ARITY on compilers that support perfect forwarding. User code can now check for this support by detecting the configuration macro BOOST_PARAMETER_HAS_PERFECT_FORWARDING, or manually turn off this support by defining the configuration macro BOOST_PARAMETER_DISABLE_PERFECT_FORWARDING.
Added metafunctions boost::parameter::is_argument_pack (#27), boost::parameter::are_tagged_arguments (#52), and boost::parameter::result_of::compose (#75).
Added variadic function template boost::parameter::compose() which takes in named arguments and returns them in an argument pack (#52). For compilers that do not support perfect forwarding, the configuration macro BOOST_PARAMETER_COMPOSE_MAX_ARITY determines the maximum number of arguments that boost::parameter::compose() can take in (#61).
Added code generation macros BOOST_PARAMETER_BASIC_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_BASIC_CONST_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_FUNCTION, BOOST_PARAMETER_NO_SPEC_MEMBER_FUNCTION, BOOST_PARAMETER_NO_SPEC_CONST_MEMBER_FUNCTION, BOOST_PARAMETER_NO_SPEC_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_CONST_FUNCTION_CALL_OPERATOR, BOOST_PARAMETER_NO_SPEC_CONSTRUCTOR, and BOOST_PARAMETER_NO_SPEC_NO_BASE_CONSTRUCTOR (#52).
Added support for Boost.MP11 (#47) (#66) (#70). User code can now check for this support by detecting the configuration macro BOOST_PARAMETER_CAN_USE_MP11, or manually turn off this support by defining the configuration macro BOOST_PARAMETER_DISABLE_MP11_USAGE.
Improved support for parameter-dependent return types via SFINAE (#73).
PtrContainer:
Fix a ptr_vector regression introduced in 1.66.0 (#24).
PolyCollection:
Maintenance work.
SmartPtr:
Added aliasing constructors to weak_ptr
Added weak_ptr<T>::empty()
Added enable_shared_from, shared_from, and weak_from
Stacktrace:
Fixed output of name(), source_location() and source_line() for the default constructed frame with thread sanitizer builds in C++98 mode.
Fixed output of long strings from name() and source_location() on MSVC #78.
Maintenance work.
Test:
Boost.test v3.11 see the Changes log for more details.
Breaking changes:
Boost.Test shows deprecation warnings if some very old headers as deprecated. If you encounter such warnings, please follow the indications: those headers will be removed in a future release.
New feature:
Now BOOST_TEST can be used to compare abstract types
Bug fixes and pull requests:
GitHub Issues: #209, #218
GitHub Pull Requests: #219, #224
Utility:
Implemented function template ostream_string in <boost/utility/ostream_string.hpp> to optimally write any kind of string content to an output stream. It satisfies the requirements of [ostream.formatted.reqmts]. (Glen Fernandes)
Optimized the stream output operators of basic_string_view and basic_string_ref to write directly to the rdbuf stream buffer. (Glen Fernandes)
Uuid:
Breaking change: MD5 name-based uuid generation was corrected to be identical on all endian systems. Define BOOST_UUID_COMPAT_PRE_1_71_MD5 to keep the result in a format compatible with 1.66 through 1.70. This does not affect the default name-based uuid generation which is based on SHA1. (#109)
Variant:
Fixed compilation of boost::apply_visitor with variants passed by non const reference in #68. Many thanks to Ed Catmur for providing the fix.
Added support for std::hash (#49). Macro BOOST_VARIANT_DO_NOT_SPECIALIZE_STD_HASH could be defined to avoid those specializations.
Added micro optimizations for binary size and performance by Nikita Kniazev in #63 and #66.
Maintenance work, including #64 by Nikita Kniazev and #67 by Hans Dembinski.
YAP:
Added an example showing how to make self-evaluating YAP expressions (that is, expressions that don't need an explicit call to evaluate() or transform()).

Context:
#91: cleanup of stack if creating ucontext fails
#97: add missing BOST_CONTEXT_DECL in stack_context
#98: fix jump_i386_sysv_macho writing garbage to the x87 control word
Coroutine2:
#28: don't crash on pthread_cancel
DLL:
New macro BOOST_DLL_USE_STD_FS. Define it to 1 to make the Boost.DLL use C++17's std::filesystem::path, std::system_error and std::error_code (#21). Note that exception types change from boost::system::system_error to std::system_error, so make sure to update catches.
Significant rewrite of the dynamic loadable detection and decoration logic. More precise errors are now reported in case of loading failures. Added shared_library::decorate() function that returns a decorated path to the library without doing any platform related queries and detections. Prefer using shared_library::load and shared_library constructors for better results (many thanks to Loïc Touraine for the work PR#23).
CI hardening, docs updates, typos fixes, cleanups and mg
#196: fix high contention on remote_ready_splk_
Filesystem:
Fixed a few instances of dereferencing std::string::end() in path implementation.
Fixed program termination in case of out of memory condition in directory iteratorsnce to error_code. (#58)
Fixed possible linking errors caused by missing definitions of static members of path. (#12759)
Fixed possible use of uninitialized data in directory iterator increment operation on Linux.
Added support fortatus query overloads for directory_entry. This avoids a relatively expensive OS query when file status is requested for a result of dereferencing a directory iterator. (PR#55)
Reworked current_path and read_symlink implementation to avoid possiblfilesystems. The functions now have an internal limit of the path size they will accept from the OS, which is currently 16 MiB.
Increased the size of the internal buffer used by copy_file.
Integer:
Added Extended Euclidean Algorithm and Modular Multiplicative Inverse function. (Nick Thompson, PR#11)
Log:
New features:
Added support for generating another log file name before collecting the file in the text file sink backend. This allows to combine appending to aexisting log file with timestamps and file counters in log filenames, and, consequently, file collection in general.
See changelog for more details.

Multi-index Containers:
size_type and difference_type are now defined as the allocator's same-named types. This will not make any difference in the vast majority of cases, but allows for some degreevia user-defined allocator types (see issue #17 for motivation). For the moment being, this change is not documented in the reference section (i.e., it has semi-official status).
Maintenance work.

boost: updated to 1.69.0 New Libraries Safe Numerics: A library for guaranteed correct integer arithmetic for C++14 and later, from Robert Ramey. Updated Libraries Any: Fixed issue with visibility. Now boost::any variables constructed in one shared library with hidden visibility could be used and destroyed in other shared library with hidden visibility. Maintenance: dropped some dependencies on other Boost libraries, fixes for docs. Asio: Fixed a problem with the detection of std::future availability with libstdc++. Fixed compile error in regex overload of read_until. Fixed a timer heap corruption issue that can occur when moving a cancelled timer. Fixed detection of std::experimental::string_view and std::string_view with newer clang/libc++. Fixed MSVC version detection for availability of std::invoke_result. Fixed the buffer sequence traits to test the new requirements, if decltype is available. Fixed an MSVC issue when building with exceptions disabled. Added SSL context options for TLS v1.3. Added a compile-time test for TLS v1 support. Fixed the macro used to test for TLS v1.2 support. Prevented global objects from being created once per thread on Windows. Fixed a crash when using size(), max_size() or empty() on default-constructed resolver results. Changed to move the return value in basic_resolver_results::begin() to avoid copying. Enabled move support for the Intel Compiler. Fixed std::string_view detection issue when using clang-cl. Fixed the handler tracking operation name for io_context::executor_type::dispatch. Fixed a buffer overflow that could occur when parsing an address string with a 64-bit scope id. Added examples showing how to write composed operations. Added C++11 versions of the Timeouts, Timers, SOCKS4 and SSL examples. Fixed minor issues in documentation and examples. Assign: Add rvalue reference, perfect forwarding, and variadic template support Avoid conversion to container's allocator Beast: This version fixes some issues in the examples, and provides a new experimental socket which supports built-in timeouts on asynchronous operations. New CppCon 2018 websocket chat example and presentation video. For a complete list of changes, please view the official Release Notes. CircularBuffer: Use the empty base optimization for storing allocators that are empty and not final (Glen Fernandes). Concept Check: Removed dependency on mpl. Context: duplicate alias should be missing GCC alias the clang-win toolset (clang-cl.exe) uses masm from the underlying msvc remove useless lines in Jamfile.v2 add .file section for *_elf_gas.S files Core: Implemented boost::empty_value, for library authors to conveniently leverage the Empty Base Optimization to store objects of potentially empty types (Glen Fernandes). This facility is now used in Boost.Beast, Boost.CircularBuffer, Boost.MultiArray, and more. Implemented boost::quick_exit to provide the C++11 standard library facility std::quick_exit functionality (Peter Dimov). Reduced the number of statics in Lightweight Test, and employ lighter abort behavior for MSVC compilers upon failure to call boost::report_errors (Glen Fernandes). DLL: Resolved link issues with the smart library Maintenance: fixes for docs and tests. Dynamic Bitset: Performance improvements (over 2x in some cases). Added range-based set, reset, flip methods Fiber: unbuffered_channel push not return Remove UTF-8 BOM at begining of the file Fix boost-install use; should only be issued once Filesystem: Don't use readdir_r on Linux and Android since the readdir function is already thread-safe. Fixed crashes in boost::filesystem::copy due to undefined behavior in the implementation. Fixed undefined behavior in boost::filesystem::directory_iterator implementation. Fixed compilation errors when using directory iterators with BOOST_FOREACH. Removed workarounds for older PGI C++ compiler versions to fix compilation on the newer ones. Fixed MSVC warnings about narrowing conversions. Flyweight: Fixed some issues in GCC related to Boost.MPL placeholder expression handling. Maintenance fixes. Function: Removed dependencies on mpl, test Geometry: Karney's solution of direct geodesic problem for internal use Discrete Frechet and Hausdorff distance algorithms New run-time and upgraded compile-time SRS transformation interfaces (undocumented for now due to potential interface changes). Integer: boost/pending/integer_log2.hpp header is deprecated and will be removed in future releases. Use boost/integer/integer_log2.hpp instead. Iostreams: Remove call to nonexistent member seekpos() of std::fpos Iterator: Fixed compilation problems with ambiguous unqualified calls to advance and distance on iterators whose types involve types in the namespace boost. LexicalCast: Fixed sign-conversion warnings Maintenance: dropped some dependencies on other Boost libraries, fixed build system warnings. Log: General changes: Updated syslog sink backend to avoid using deprecated Boost.ASIO interfaces. Bug fixes: Fixed a possible incorrect estimation of the total size of rotated files in the target directory of a text file sink in some cases. See changelog for more details. Logic: Breaking change: Use explicit operator bool when available Math: Add LambertW functions. Update integration routines to support complex valued integrands and contour integrals. Added the derivative of the Barycentric rational approximation. Minor fixes to better support variable precision floating point types. Removed use of deprecated Boost.Endian in favour of Predef. Updated continued fraction and series evaluation code to support complex types. Prevent logic error leading to infinite loop in toms748_solve. Fix mean and standard_deviation for extreme_value_distribution. Improve heuristics used in newton_raphson_iterate. Fix result of erf(NaN). Big push to reduce GCC warnings. Refactor polynomial addition. Fix for vxWorks having a real function in the global namespace. Improve sinc approximations and add better tests. Fix typo in Student's T hypothesis testing documentation, Mp11: Implemented the mp_starts_with facility (Glen Fernandes). MultiArray: Improve C++11 allocator model support including: Support for C++11 minimal allocators, support for stateful allocators, using the allocator for construction and destruction of the value type, and using the empty base optimization for storing empty or stateless allocators (Glen Fernandes). Multi-index Containers: Introduced an alternative terse key specification syntax for C++17 compliant environments. Multiprecision: Big update to better support variable precision types so that the precision of the result is always the largest of all the arguments. Add support for allocators that are final in __cpp_int (Glen Fernandes). Removed use of deprecated Boost.Endian in favour of Predef. Add support for std::string_view. Fixed minor bug in constant initialization. Make assignment of non-finite value to cpp_int a runtime errors. Added typedefs for cpp_bin_float_oct and cpp_complex_oct. PolyCollection: Added Bost.PolyCollection-specific versions of algorithms std::for_each_n and std::sample. Pool: Replace boost::mutex use to avoid a dependency on Boost.Thread Preprocessor: Supports the new C++ standard conforming preprocessor in VC++ 14.1, which is currently enabled by using the /experimental:preprocessor switch, in Visual Studio 2017 15.8 on up. Rational: Add constexpr support Spirit.X3: Drop own FP routines in favor of boost::math Missing visibility mark on exception types to_utf8: Fixed wchar_t handling on Windows Spirit V2 Drop own FP routines in favor of boost::math Missing visibility mark on exception types Fixed transform_attribute ambiguity to_utf8: Fixed wchar_t handling on Windows Spirit.Classic: Missing visibility mark on exception types Stacktrace: libbacktrace usage was significantly improved. BOOST_STACKTRACE_USE_BACKTRACE or boost_stacktrace_backtrace users are encouraged to update: Memory consumprion dropped down. Stack capturing became faster by an order of magnitude. syminfo fallback enabled to provide information for visible symbols even without debug information Exact location of the backtrace.h header now can be specified via BOOST_STACKTRACE_BACKTRACE_INCLUDE_FILE, to allow backtrace.h header usage on platforms and compilers where that header is unreachable otherwise (for example Ubuntu Xenial + Clang) Optimized stack capturing if max_depth is set Added to_string(const stacktrace& ) functions for fast conversion of stacktraces to std::string System: Boost.System is now header-only. A stub library is still built for compatibility, but linking to it is no longer necessary. Even more functions have been marked constexpr. The destructor of error_category is now protected and no longer virtual. This is a potentially breaking change, but its impact is expected to be limited. error_category now has a constructor that accepts a 64 bit identifier, enabling distinct category objects to compare equal. The constructors of error_category are now protected. A non-allocating, nonthrowing overload of message has been added. A virtual function failed has been added, allowing categories for which success is not synonymous with 0. The deprecated boost::system::throws object has been removed. boost::throws() is now deprecated and its use is discouraged. The constructor of system_error taking a single error_code argument is now explicit. system_error::code() now returns by value. Test: Boost.test v3.9 see the Changes log for more details. New feature: Official support of header-only variant of Boost.Test with multiple translation units. Now possible to manually add a test case by specifying its name, with BOOST_TEST_CASE_NAME Better support of boost::exception in the logs TypeIndex: Fix the regression and speed up parsing of the boost/type_traits.hpp header by 30% Utility: Added support for non-inheritable empty types to boost::compressed_pair by avoiding the empty base optimization for types which are declared as final (Glen Fernandes). Variant: Fixed issue with visibility. Now boost::bad_visit exception could cross the boundaries of shared library with hidden visibility and could be catched in other shared library with hidden visibility. YAP: Minor changes to support MSVC++ version 14.15 (Visual Studio 2017 version 15.8). Doc fixes.

Diff to previous 1.25 (colored) to selected 1.7 (colored)
boost: updated to 1.67.0 Version 1.67.0: New Libraries: - Contract: Contract programming for C++. - HOF: Higher-order functions for C++. Updated Libraries: - Asio: Added missing const qualifier to basic_socket_acceptor::get_option. Worked around a parsing error that occurs with some versions of gcc. Fixed broken code samples in tutorial. Added new experimental features. (Note that "experimental" features may be changed without notice in subsequent releases.) Added experimental::detached completion token. Added experimental::redirect_error completion token. Added experimental::co_spawn facility for integration with the coroutines technical specification. Updated timeout examples to use latest features. Used asio::steady_timer rather than asio::deadline_timer. Used asio::dynamic_buffer rather than asio::streambuf. Used timed asio::io_context::run_for() function for blocking clients. Added example showing a custom completion token for blocking with timeouts. Fixed unit tests to compile when BOOST_ASIO_NO_DEPRECATED is defined. Changed socket iostreams to use chrono by default, to fix compatibility with the Networking TS. Define BOOST_ASIO_USE_BOOST_DATE_TIME_FOR_SOCKET_IOSTREAM to enable the old Boost.Date_Time interface in basic_socket_streambuf and basic_socket_iostream. Updated examples to use chrono rather than Boost.Date_Time. Fixed an incorrect member function detector in the is_dynamic_buffer trait. Fixed an async_result incompatibility with deprecated handler_type. Added a missing move optimisation in the SSL stream implementation. Fixed incorrect basic_resolver_results::value_type typedef. Fixed a compile error with some OpenSSL versions when SSL_OP_NO_COMPRESSION is defined. Changed add_certificate_authority to process multiple certificates in a bundle. Eliminated deprecation warning with MSVC by using std::invoke_result rather than std::result_of. Changed to use std::string_view for C++17 or later, and std::experimental::string_view for C++14. Define the preprocessor macro BOOST_ASIO_DISABLE_STD_STRING_VIEW to force the use of std::experimental::string_view (assuming it is available) when compiling in C++17 mode. Ensured DynamicBuffer template arguments are decayed before using in enable_if tests. Changed documentation to distinguish legacy completion handlers (which are still required to be CopyConstructible) from new MoveConstructible handlers. Suppressed a discarded return value warning in the buffer debugging support. Fixed basic_yield_context to work with completion signatures containing reference parameters. Ensured that stackful coroutines launched using spawn() correctly store decayed copies of their function and handler arguments. Fixed some compatibility issues with Android. Added cross-compilation support to Jamfiles. Fixed some minor portability issues in examples. - Atomic: Breaking change: Changed the result of the (op)_and_test operations added in Boost 1.66 to the opposite - the functions now return true if the operation result is non-zero. This is consistent with other test methods in Boost.Atomic and the C++ standard library. Users can define BOOST_ATOMIC_DETAIL_HIGHLIGHT_OP_AND_TEST when compiling their code to emit warnings on every use of the changed functions. This way users can locate the code that needs to be updated. Update for C++2a. On C++11 compilers that support scoped enums, the memory_order enumeration is now scoped and contains constants with shorter names like acquire, release or seq_cst (i.e. users can use memory_order::acquire instead of memory_order_acquire). The old constants are also provided for backward compatibility. (P0439R0) Update for C++2a. Added experimental support for atomic operations on floating point types. In addition to general operations, add, sub, negate operations and their fetch_(op) and opaque_(op) versions are supported. Lock-free property can be tested with the new macros BOOST_ATOMIC_FLOAT/DOUBLE/LONG_DOUBLE_LOCK_FREE. The support for floating point types is optional and can be disabled by defining BOOST_ATOMIC_NO_FLOATING_POINT. (P0020R6) Added new experimental operations: negate_and_test and complement_and_test which perform negation or bitwise complement and return true if the result is not zero. add, sub, negate, bitwise_and, bitwise_or, bitwise_xor, bitwise_complement operations which perform the operation and return its result. For generic atomic<T> specialization, the default constructor is now trivial if T's default constructor is. The internal implementation of atomic<T> has been updated to avoid undefined behavior that stems from signed integer overflows. As required by the C++ standard, the library uses two's complement representation of signed integers internally and accroding rules of overflow. Currently, the library requires the native signed integer types to also use two's complement representation (but no defined overflow semantics). Improved Clang support. In particular, fixed DCAS not being lock-free and fixed possible incorrect code generated on 32-bit x86. Improved MinGW support. For gcc versions up to 4.6, fixed compilation of DCAS on x86. In x86 PIE code, asm blocks now preserve ebx value. - Beast: This version fixes significant defects in websocket::stream which can lead to asserts or undefined behavior. Users are encouraged to update to the latest Boost release. For a complete list of changes, please view the official Release Notes. - ContainerHash: Extracted from the functional module to break a dependency cycle. Moved headers to new location to reflect name change, the old include paths will still work. Added support for std::string_view, std::error_code, std::error_condition, std::optional, std::variant, std::monostate where available. Added explicit support for vector<bool>, so that it will work with libc++. More detail in the library change log. - Context: fix i386/macho routines to correctly return transfer_t in EAX/EDX __sanitizer_finish_switch_fiber should be called directly after context switch Clang on Windows : error: No best alternative for libs/context/build/asm_sources fixing C2492 for execution_context (v1) known bug: including all.hpp + <context-impl>ucontext/winfib causes error 'forced_unwind: is not a member of boost::context::detail' More info https://www.boost.org/users/history/version_1_67_0.html

Changes 1.63.0:
Atomic:
* Added the static constant atomic<T>::is_always_lock_free for conformance with C++17. The constant indicates that the given specialization always provides lock-free implementation of atomic operations.
* Improved support of Oracle Studio on x86 targets.
Container:
* Fixed bugs
Context:
* 11687 Xcode (Apple clang) and thread_local
* 12114 context does not preserve fpu context on ios arm64 devices (fixed for other architecturs too)
* 12411 fpu registers not preserved with O2 optimizations in Visual Studio (fixed for other architecturs too)
* 12551 building boost on arm64 causes error: unknown directive
* reduced signatur for ontop-functions
* unit-test for private fcontext-API
* performance-test for ucontext and fcontext fixed
Fiber:
* unbounded_channel and bounded_channel marked as deprecated
* new classes buffered_channel and unbuffered_channel
* performance improved
Fusion:
* Fixed fusion::vector buggy constructors (Thanks to Lee Clagett).
* BOOST_FUSION_ADAPT* and BOOST_FUSION_DEFINE* now allow empty structures. (6592)
* BOOST_FUSION_DEFINE* allows move constructor and assignment. (10099)
* Adaptor for std::array (Thanks to Mateusz oskot). (8241)
* Fixed returning temporary variable warnings on MSVC.
Geometry:
* Intersection: take care that output is valid (work in progres, not yet finished - but more is valid)
* 12289 Avoid warning/compilation error for std::cout
* 12412 Invalid result of covered_by() with geographic Points and Boxes
* 12413 rtree::remove() not working properly with geographic Points
Hash:
* Fixed some warnings.
Interprocess:
* Fixed bugs
Intrusive:
* Fixed bugs
Lexical Cast:
* Fixed issue found by -fsanitize=undefined 21
Log:
* Removed the previously deprecated type_info_wrapper.
* Added a way to access the current file name from the text file sink backend. The file name can be obtained with the get_current_file_name method.
* Bug fixes
Metaparse:
* Improved the implementation of BOOST_METAPARSE_STRING
Move:
* Improved experimental adaptive sort algorithm performance
* Activate BOOST_MOVE_FORCEINLINE
Optional:
* Added two new in-place constructors. They work similarly to emplace() functions: they initialize the contained value by perfect-forwarding the obtained arguments. One constructor always initializes the contained value, the other based on a boolean condition.
* Syntax o = {} now correctly un-initializes an optional, just like in std::optional.
* Fixed optional<optional<T>&> initialization. (12203)
* Optional constructors are sfinae-friendly. This fixes interaction with std::tuple. (12563)
Phoenix:
* Most of modules now support C++11 variadic templates.
* Fixed type deduction failure with result type.
* Suppress unused warnings.
* Fixed too few arguments error on binary math functions.
* Added workarounds for older compiler.
Python:
* Added (basic) support for C++11 (std::shared_ptr, std::unique_ptr)
* Incorporated an extension API to wrap NumPy
* Removed obsolete bits and pieces
Test:
* Boost.test v3.4 see the Change log section for more details.
* New feature: per_element and lexicographic modifiers of BOOST_TEST can also be applied to string comparison
* Breaking change: colons that appear in test case names are replaced with underscores
* Bug fixes
TypeIndex:
* Added runtime_cast to the library as an emulation of dynamic_cast. Thanks to Chris Glover for the implementation. See runtime_cast reference for more info.
* Internals of the CTTI were made more platform independant, due to change of the std::size_t type to unsigned int.
Units:
* Fix inspection warnings
* updated physico-chemical constants to CODATA 2014 values
* define biot correctly as 10 Ampere
Unordered:
* Fix an exception safety issue in assignment.
* Use std::allocator_traits where available, and support modern style rebind (12459).
* Add some allocator aware constructors.
* Use the hint iterator in emplace_hint.
* Fixed some warnings.

Changes 1.61.0: New Libraries: -------------- Compute: Parallel/GPU-computing library DLL: Library for comfortable work with DLL and DSO. Library provides a portable across platforms way to: * load libraries * import any native functions and variables * make alias names for C++ mangled functions and symbols * query libraries for sections and exported symbols * self loading and self querying * getting program and module location by exported symbol Hana: A modern C++ metaprogramming library. It provides high level algorithms to manipulate heterogeneous sequences, allows writing type-level computations with a natural syntax, provides tools to introspect user-defined types and much more. Metaparse: A library for generating compile time parsers parsing embedded DSL code as part of the C++ compilation process. The library is similar to Spirit, however while parsers built with Spirit parse at run-time, parsers built with Metaparse parse at compile-time.

Fixed an issue in the kqueue reactor which resulted in spinning when using serial ports on Mac OS. Fixed kqueue reactor support for read-only file descriptors. Fixed a compile error when using the /dev/poll reactor. Changed the Windows backend to use WSASocketW, as WSASocketA has been deprecated. Fixed some warnings reported by Visual C++ 2013. Fixed integer type used in the WinRT version of the byte-order conversion functions. Changed documentation to indicate that use_future and spawn() are not made available when including the asio.hpp convenience header. Explicitly marked asio::strand as deprecated. Use asio::io_service::strand instead. Circular Buffer: Fixed some warnings and move_if_noexcept from Boost.Move is used Config: BOOST_HAS_PRAGMA_DETECT_MISMATCH macro was added Container: Added support for initializer_list.

Changes 1.56.0: Modularization Boost version control has migrated to a system using git submodules. This shouldn't make too much of a difference to users, although the directory structure is now a bit different. Parts of some libraries have been moved into different modules, and several new modules have been extracted from existing code. All header paths should remain the same. The new modules are: Assert: Customizable assert macros. Maintained by Peter Dimov. Core: Core utilities used by other libraries, with minimal dependencies. Maintained by Peter Dimov, Glen Fernandes and Andrey Semashev. Lexical_Cast: General literal text conversions, such as an int represented a string, or vice-versa, from Kevlin Henney. Throw_Exception: A common infrastructure for throwing exceptions from Boost libraries, from Emil Dotchevski. Winapi: Windows API declarations without <windows.h>, for internal Boost use. New Libraries Align: Memory alignment functions, allocators, and adaptors, from Glen Fernandes. Type_Index: Runtime/Compile time copyable type info, from Antony Polukhin.

New Libraries
* Icl: Interval Container Library, interval sets and maps and aggregation of
associated values, from Joachim Faulhaber.
Updated Libraries
* Array:
- Added support for cbegin/cend

recurse into directory symlinks.
- Reference documentation cleanup, including fixing missing and broken links,
and adding missing functions.
- Miscellaneous implementation code cleanup.
* Fusion:
- vector copy constructor now copies sequence members in the same order on different platforms
* Graph:
- Fixed Graphviz output to work on Visual C++ 7.1.
- Replaced assert with BOOST_ASSERT.
- Changed to Boost.Filesystem v3.

Updated Libraries Build System: * When cross-compiling to GNU targets, static libraries are properly created. Previously, using such libraries resulted in Archive has no index error. * The naming of DLL and import libraries with gcc compiler on Windows, both mingw and cygwin, now matches default conventions of those environments. Previously, the naming scheme was the same as for other Windows compilers. Updated Tools: * Quickbook: Unicode escape characters. * Support the UTF-8 byte order mark. * Disallow [ in simple markup. Fixes some errors with mismatched punctuation. * Add a command line flag (-D) to define macros at the command line. * Improved post-processor output. * Check that [section] and [endsect] tags are balanced in templates.

Update boost to 1.34.1. This is based on the patches provided by Brook Milligan
in PR pkg/36558. Committing it right after the freeze so that we have enough
time to resolve the problems that this will surely cause.
New Libraries
* Foreach Library:
BOOST_FOREACH macro for easily iterating over the elements of a
sequence, from Eric Niebler.
* Statechart Library:
Arbitrarily complex finite state machines can be implemented in
easily readable and maintainable C++ code, from Andreas Huber.
* TR1 Library:
An implementation of the C++ Technical Report on Standard Library
Extensions, from John Maddock.
This library does not itself implement the TR1 components, rather
it's a thin wrapper that will include your standard library's TR1
implementation (if it has one), otherwise it will include the Boost
Library equivalents, and import them into namespace std::tr1. Highlights
include: Reference Wrappers, Smart Pointers, result_of,
Function Object Binders, Polymorphic function wrappers, Type Traits,
Random Number Generators and Distributions, Tuples, Fixed Size Array,
Hash Function Objects, Regular Expressions and
Complex Number Additional Algorithms.
* Typeof Library:
Typeof operator emulation, from Arkadiy Vertleyb and Peder Holt.
* Xpressive Library:
Regular expressions that can be written as strings or as expression
templates, and that can refer to each other and themselves recursively
with the power of context-free grammars, from Eric Niebler.
Updated Libraries
* Assign Library:
o Support for ptr_map<key,T> via the new function ptr_map_insert()
o Support for initialization of Pointer Containers when the containers
hold pointers to an abstract base class.
* Date_time library:
o Support for new US/Canada timezone rules and other bug fixes.
See Change History for details.
* Filesystem Library:
Major upgrade in preparation for submission to the C++ Standards Committee
for TR2. Changes include:
o Internationalization, provided by class templates basic_path,
basic_filesystem_error, basic_directory_iterator
and basic_directory_entry.
o Simplification of the path interface by eliminating special constructors
to identify native formats.
o Rationalization of predicate function design, including the addition of
several new functions.
o Clearer specification by reference to POSIX, the ISO/IEEE Single Unix
Standard, with provisions for Windows and other operating systems.
o Preservation of existing user code whenever possible.
o More efficient directory iteration.
o Addition of a recursive directory iterator.
* Function Library:
Boost.Function now implements a small buffer optimization, which can
drastically improve the performance when copying or constructing
Boost.Function objects storing small function objects. For instance,
bind(&X:foo, &x, _1, _2) requires no heap allocation when placed into
a Boost.Function object.
* Functional/Hash Library
o Use declarations for standard classes, so that the library doesn't
need to include all of their headers
o Deprecated the <boost/functional/hash/*.hpp> headers.
o Add support for the BOOST_HASH_NO_EXTENSIONS macro, which disables
the extensions to TR1
o Minor improvements to the hash functions for floating point numbers.
* Graph Library:
o edmonds_maximum_cardinality_matching, from Aaron Windsor.
o lengauer_tarjan_dominator_tree, from JongSoo Park.
o compressed_sparse_row_graph, from Jeremiah Willcock and Douglas Gregor
of Indiana University.
o sorted_erdos_renyi_iterator, from Jeremiah Willcock
of Indiana University.
o biconnected_components now supports a visitor and named parameters,
from Janusz Piwowarski.
o adjacency_matrix now models the Bidirectional Graph concept.
o dijkstra_shortest_paths now calls vis.initialize_vertex for each
vertex during initialization.
o Note: the name of the compiled library for the GraphViz reader has
changed to boost_graph (from bgl-viz) to match Boost conventions.
o See the complete revision history for more information.
* MultiArray Library:
Boost.MultiArray now by default provides range-checking for operator[].
Range checking can be disabled by defining the macro BOOST_DISABLE_ASSERTS
before including multi_array.hpp. A bug in multi_array::resize() related
to storage orders was fixed.
* Multi-index Containers Library:
o New random access indices.
o Non key-based indices feature new rearrange facilities.
o This version also includes a number of optimizations and usage
improvements. For a complete list of changes,
see the library release notes.
* Optional Library:
o boost::none_t and boost::none now added to Optional's documentation
o Relational operators now directly support arguments of type 'T'
and 'none_t'
o operator->() now also works with reference types.
o Helper functions make_optional(val), make_optional(cond,val)
and get_optional_value_or(opt,alternative_value) added.
o Constructor taking a boolean condition (as well as a value) added.
o Member function get_value_or(alternative_value) added.
o Incompatbility bug with mpl::apply<> fixed.
o Converting assignment bug with uninitialized lvalues fixed.
* Parameter Library:
o Every ArgumentPack is now a valid MPL Forward Sequence.
o Support for unnamed arguments (those whose keyword is deduced from
their types) is added.
o Support for named and unnamed template arguments is added.
o New overload generation macros solve the forwarding problem directly.
o See also the Python library changes, below.
* Pointer Container Library:
o Support for serialization via Boost.Serialization.
o Exceptions can be disabled by defining the macro
BOOST_PTR_CONTAINER_NO_EXCEPTIONS before including any header.
This macro is defined by default if BOOST_NO_EXCEPTIONS is defined.
o Additional std::auto_ptr<T> overloads added s.t. one can also pass
std::auto_ptr<T> instead of only T* arguments to member functions.
o transfer() now has weaker requirements s.t. one can transfer objects
from ptr_container<Derived> to ptr_container<Base>,
* Python Library:
o Boost.Python now automatically appends C++ signatures to docstrings.
The new docstring_options.hpp header is available to control the
content of docstrings.
o stl_input_iterator, for turning a Python iterable object into an STL
input iterator, from Eric Niebler.
o Support for void* conversions is added.
o Integrated support for wrapping C++ functions built with the
parameter library; keyword names are automatically known to
docsstrings.
o Enhancements to the API for better embedding support
(boost::python::import(), boost::python::exec()
and boost::python::exec_file()).
* Signals Library:
More improvements to signal invocation performance from Robert Zeh.
* Smart Pointers Library:
o Allocator support as proposed in N1851 (162 Kb PDF).
o pointer_cast and pointer_to_other utilities to allow
pointer-independent code, from Ion Gaztanaga.
* String Algorithm Library:
o lexicographical_compare
o join
o New comparison predicates is_less, is_not_greater.
o Negative indexes support (like Perl) in various algorihtms
(*_head/tail, *_nth).
* Wave Library:
o Wave now correctly recognizes pp-number tokens as mandated by the
C++ Standard, which are converted to C++ tokens right before they are
returned from the library.
o Several new preprocessing hooks have been added. For a complete
description please refer to the related documentation page:
The Context Policy.
o Shared library (dll) support has been added for the generated Wave
libraries.
o The overall error handling has been improved. It is now possible to
recover and continue after an error or a warning was issued.
o Support for optional comment and/or full whitespace preservation
in the generated output stream has been added.
o The Wave library now performs automatic include guard detection to
avoid accessing header files more than once, if appropriate.
o Full interactive mode has been added to the Wave tool. Now the Wave
tool can be used just like Python or Perl for instance to
interactively try out your BOOST_PP macros. Additionally it is now
possible to load and save the current state of an interactive
session (macro tables et.al.).
o The overall performance has been improved by upto 40-60%, depending
on the concrete files to process.
o Support for new pragmas has been added allowing to control certain
library features from inside the preprocessed sources (partial
output redirection, control of generated whitespace and #line
directives).
o Optional support for #pragma message "..." has been added.
o This version also includes a number of bug fixes and usage
improvements. For a complete list of changes, see the libraries
change log.

Complete rework of the Boost packages:
- Drop devel/boost and devel/boost-thread.
- Add devel/boost-docs which includes all the documentation related to Boost
(previously included in devel/boost).
- Add devel/boost-build which includes bjam, the Boost.Build framework.
- Add devel/boost-headers which includes all the header files needed at build
time by programs using Boost (previously included in devel/boost).
- Add devel/boost-libs which includes all the binary libraries needed at build
and run time by programs using Boost (previously included in devel/boost and
devel/thread). All of them are multithreaded, to make things easier.
- devel/boost-python includes the Boost Python library (as it did before), but
now works, given that everything is threaded again.
- Drop our thread_user.hpp customization. Avoids some build failures that
appeared when the previous boost-thread package was not installed.
- Use static PLISTs.
- Install unversioned files. Makes things *a lot* easier when building stuff
outside pkgsrc.
- Add meta-pkgs/boost, a meta package that depends on all of the above.
Thanks go to jlam@ and tv@ for their comments.
While here, update to 1.32.0:
New Toolset Names
The names of some the Boost.Build toolsets have been changed to remove the "."
(dot) character and to fix some other naming inconsistencies. For example,
vc7.1 toolset was renamed to become vc-7_1. Please refer to the Supported
Toolsets section of the installation guide for the complete list of the current
toolset names. This change was made as a part of the effort to make the Boost
distribution compatible with ISO 9660 level 2 requirements.
