protobuf: updated to 3.11.0

Protocol Buffers v3.11.0

C++
Make serialization method naming consistent
Make proto runtime + generated code free of deprecation warnings
Moved ShutdownProtobufLibrary() to message_lite.h. For backward compatibility a declaration is still available in stubs/common.h, but users should prefer message_lite.h
Removed non-namespace macro EXPECT_OK()
Removed mathlimits.h from stubs in favor of using std::numeric_limits from C++11
Fixed bug in parser when ending on a group tag
Add a helper function to UnknownFieldSet to deal with the changing return value of message::unknown_fields()
Fix incorrect use of string_view iterators
Support direct pickling of nested messages
Skip extension tag validation for MessageSet if unknown dependencies are allowed
Updated deprecation macros to annotate deprecated code
Remove conversion warning in MapEntryFuncs::ByteSizeLong
Revert "Make shared libraries be able to link to MSVC static runtime libraries, so that VC runtime is not required."

Python
Add float_precision option in json format printer
Optionally print bytes fields as messages in unknown fields, if possible
FieldPath: fix testing IsSet on root path ''

protobuf: updated to 3.10.0

Protocol Buffers v3.10.0

C++

Switch the proto parser to the faster MOMI parser.
Properly escape Struct keys in the proto3 JSON serializer.
Fix crash on uninitialized map entries.
Informed the compiler of has-bit invariant to produce better code
Unused imports of files defining descriptor extensions will now be reported
Add proto2::util::RemoveSubranges to remove multiple subranges in linear time.
Added BaseTextGenerator::GetCurrentIndentationSize()
Made implicit weak fields compatible with the Apple linker
Support 32 bit values for ProtoStreamObjectWriter to Struct.
Removed the internal-only header coded_stream_inl.h and the internal-only methods defined there.
Enforced no SWIG wrapping of descriptor_database.h (other headers already had this restriction).
Implementation of the equivalent of the MOMI parser for serialization. This removes one of the two serialization routines, by making the fast array serialization routine completely general. SerializeToCodedStream can now be implemented in terms of the much much faster array serialization. The array serialization regresses slightly, but when array serialization is not possible this wins big.
Do not convert unknown field name to snake case to accurately report error.
Fix a UBSAN warnings.
Add podspec for C++
protoc: fix source code info location for missing label
C++ Add move constructor for Reflection's SetString

Optimize and simplify implementation of RepeatedPtrFieldBase
Don't create unnecessary unknown field sets.
Remove branch from accessors to repeated field element array.
Added delimited parse and serialize util.
Reduce size by not emitting constants for fieldnumbers
Fix a bug when comparing finite and infinite field values with explicit tolerances.
TextFormat::Parser should use a custom Finder to look up extensions by number if one is provided.
Add MessageLite::Utf8DebugString() to make MessageLite more compatible with Message.
Fail fast for better performance in DescriptorPool::FindExtensionByNumber() if descriptor has no defined extensions.
Adding the file name to help debug colliding extensions
Added FieldDescriptor::PrintableNameForExtension() and DescriptorPool::FindExtensionByPrintableName().
The latter will replace Reflection::FindKnownExtensionByName().
Replace NULL with nullptr
Created a new Add method in repeated field that allows adding a range of elements all at once.
Enabled enum name-to-value mapping functions for C++ lite
Avoid dynamic initialization in descriptor.proto generated code
Move stream functions to MessageLite from Message.

protobuf: updated to 3.8.0

Protocol Buffers v3.8.0
C++
Use std::atomic in case of myriad2 platform
Always declare enums to be int-sized
Added DebugString() and ShortDebugString() methods on MessageLite
Specialized different parse loop control flows
Make hasbits potentially in register. The or's start forming an obstacle because it's a read modify store on the same mem address on each iteration.
Move to an internal MACRO for parser validity checks.
Improve map parsing performance.
Make MergePartialFromCodedStream non virtual. This allows direct calls, potential inlining and is also a code health improvement
Add an overall limit to parse_context to prevent reading past it. This allows to remove a annoying level of indirection.
Fix a mistake, we shouldn't verify map key/value strings for utf8 in opt mode for proto2.
Further improvements to cut binary size.
Prepare to make MergePartialFromCodedStream non-virtual.
A report on some interesting behavior change in python (caused by b/27494216) made me realize there is a check that needs to be done in case the parse ended on a end group tag.
Add a note of caution to the comments around skip in CodedOutputStream.
Simplify end check.
Add overload for ParseMessage for MessageLite/Message types. If the explicit type is not known inlining won't help de-virtualizing the virtual call.
Reduce linker input. It turns out that ParseMessage is not inlined, producing template instantiations that are used only once and save nothing but cost more.
Improve the parser.
[c++17] Changed proto2::RepeatedPtrField iterators to no longer derive from the deprecated std::iterator class.
Change the default value of case_insensitive_enum_parsing to false for JsonStringToMessage.
Add a warning if a field name doesn't match the style guide.
Fix TextFormat not round-trip correctly when float value is max float.
Added locationed info for some errors at compiler
Python reserved keywords are now working with getattr()/setattr() for most descriptors.
Added AllowUnknownField() in text_format
Append '_' to C++ reserved keywords for message, enum, extension
Fix MSVC warning C4244 in protobuf's parse_context.h.
Updating Iterators to be compatible with C++17 in MSVC.
Use capability annotation in mutex.h
Fix "UndefinedBehaviorSanitizer: cfi-bad-type"
CriticalSectionLock class as a lightweight replacement for std::mutex on Windows platforms.
Removed vestigial wire_format_lite_inl.h

Upgrade protobuf to version 3.5.0.

Pkgsrc changes:
 * Adapt PLIST.
 * After exchange, set MAINTAINER to pkgsrc-users@

Upstream changes:

2017-11-13 version 3.5.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)
  Planned Future Changes
  * Make C++ implementation C++11 only: we plan to require C++11 to build
    protobuf code starting from 3.6.0 release. Please join this github issue:
    https://github.com/google/protobuf/issues/2780 to provide your feedback.

  General
  * Unknown fields are now preserved in proto3 for most of the language
    implementations for proto3 by default. See the per-language section for
    details.
  * reserve keyword are now supported in enums

  C++
  * Proto3 messages are now preserving unknown fields by default. If you rely on
    unknowns fields being dropped. Please use DiscardUnknownFields() explicitly.
  * Deprecated the unsafe_arena_release_* and unsafe_arena_add_allocated_*
    methods for string fields.
  * Added move constructor and move assignment to RepeatedField,
    RepeatedPtrField and google::protobuf::Any.
  * Added perfect forwarding in Arena::CreateMessage
  * In-progress experimental support for implicit weak fields with lite protos.
    This feature allows the linker to strip out more unused messages and reduce
    binary size.
  * Various performance optimizations.

  Java
  * Proto3 messages are now preserving unknown fields by default. If you'd like
    to drop unknown fields, please use the DiscardUnknownFieldsParser API. For
    example:
      Parser<Foo> parser = DiscardUnknownFieldsParser.wrap(Foo.parser());
      Foo foo = parser.parseFrom(input);
  * Added a new CodedInputStream decoder for Iterable<ByteBuffer> with direct
    ByteBuffers.
  * TextFormat now prints unknown length-delimited fields as messages if
    possible.
  * FieldMaskUtil.merge() no longer creates unnecessary empty messages when a
    message field is unset in both source message and destination message.
  * Various performance optimizations.

  Python
  * Proto3 messages are now preserving unknown fields by default. Use
    message.DiscardUnknownFields() to drop unknown fields.
  * Add FieldDescriptor.file in generated code.
  * Add descriptor pool FindOneofByName in pure python.
  * Change unknown enum values into unknown field set .
  * Add more Python dict/list compatibility for Struct/ListValue.
  * Add utf-8 support for text_format.Merge()/Parse().
  * Support numeric unknown enum values for proto3 JSON format.
  * Add warning for Unexpected end-group tag in cpp extension.

  PHP
  * Proto3 messages are now preserving unknown fields.
  * Provide well known type messages in runtime.
  * Add prefix "PB" to generated class of reserved names.
  * Fixed all conformance tests for encode/decode json in php runtime. C
    extension needs more work.

  Objective-C
  * Fixed some issues around copying of messages with unknown fields and then
    mutating the unknown fields in the copy.

  C#
  * Added unknown field support in JsonParser.
  * Fixed oneof message field merge.
  * Simplify parsing messages from array slices.

  Ruby
  * Unknown fields are now preserved by default.
  * Fixed several bugs for segment fault.

  Javascript
  * Decoder can handle both paced and unpacked data no matter how the proto is
    defined.
  * Decoder now accept long varint for 32 bit integers.

Update *protobuf to 3.2.0:

2017-01-23 version 3.2.0 (C++/Java/Python/PHP/Ruby/Objective-C/C#/JavaScript/Lite)
  General
  * Added protoc version number to protoc plugin protocol. It can be used by
    protoc plugin to detect which version of protoc is used with the plugin and
    mitigate known problems in certain version of protoc.

  C++
  * The default parsing byte size limit has been raised from 64MB to 2GB.
  * Added rvalue setters for non-arena string fields.
  * Enabled debug logging for Android.
  * Fixed a double-free problem when using Reflection::SetAllocatedMessage()
    with extension fields.
  * Fixed several deterministic serialization bugs:
    * MessageLite::SerializeAsString() now respects the global deterministic
      serialization flag.
    * Extension fields are serialized deterministically as well.  Fixed protocol
      compiler to correctly report importing-self as an error.
  * Fixed FileDescriptor::DebugString() to print custom options correctly.
  * Various performance/codesize optimizations and cleanups.

  Java
  * The default parsing byte size limit has been raised from 64MB to 2GB.
  * Added recursion limit when parsing JSON.
  * Fixed a bug that enumType.getDescriptor().getOptions() doesn't have custom
    options.
  * Fixed generated code to support field numbers up to 2^29-1.

  Python
  * You can now assign NumPy scalars/arrays (np.int32, np.int64) to protobuf
    fields, and assigning other numeric types has been optimized for
    performance.
  * Pure-Python: message types are now garbage-collectable.
  * Python/C++: a lot of internal cleanup/refactoring.

  PHP (Alpha)
  * For 64-bit integers type (int64/uint64/sfixed64/fixed64/sint64), use PHP
    integer on 64-bit environment and PHP string on 32-bit environment.
  * PHP generated code also conforms to PSR-4 now.
  * Fixed ZTS build for c extension.
  * Fixed c extension build on Mac.
  * Fixed c extension build on 32-bit linux.
  * Fixed the bug that message without namespace is not found in the descriptor
    pool. (#2240)
  * Fixed the bug that repeated field is not iterable in c extension.
  * Message names Empty will be converted to GPBEmpty in generated code.
  * Added phpdoc in generated files.
  * The released API is almost stable. Unless there is large problem, we won't
    change it. See
    https://developers.google.com/protocol-buffers/docs/reference/php-generated
    for more details.

  Objective-C
  * Added support for push/pop of the stream limit on CodedInputStream for
    anyone doing manual parsing.

  C#
  * No changes.

  Ruby
  * Message objects now support #respond_to? for field getters/setters.
  * You can now compare essage == non_message_objectand it will return false
    instead of throwing an exception.
  * JRuby: fixed #hashCode to properly reflect the values in the message.

  Javascript
  * Deserialization of repeated fields no longer has quadratic performance
    behavior.
  * UTF-8 encoding/decoding now properly supports high codepoints.
  * Added convenience methods for some well-known types: Any, Struct, and
    Timestamp. These make it easier to convert data between native JavaScript
    types and the well-known protobuf types.

Updated protobuf to 3.1.0.

2016-09-23 version 3.1.0 (C++/Java/Python/PHP/Ruby/Objective-C/C#/JavaScript/Lite)
  General
  * Proto3 support in PHP (alpha).
  * Various bug fixes.

  C++
  * Added MessageLite::ByteSizeLong() that equivalent to
    MessageLite::ByteSize() but returns the value in size_t. Useful to check
    whether a message is over the 2G size limit that protobuf can support.
  * Moved default_instances to global variables. This allows default_instance
    addresses to be known at compile time.
  * Adding missing generic gcc 64-bit atomicops.
  * Restore New*Callback into google::protobuf namespace since these are used
    by the service stubs code
  * JSON support.
    * Fixed some conformance issues.
  * Fixed a JSON serialization bug for bytes fields.

  Java
  * Fixed a bug in TextFormat that doesn accept empty repeated fields (i.e.,
    ield: [ ].
  * JSON support
    * Fixed JsonFormat to do correct snake_case-to-camelCase conversion for
      non-style-conforming field names.
    * Fixed JsonFormat to parse empty Any message correctly.
    * Added an option to JsonFormat.Parser to ignore unknown fields.
  * Experimental API
    * Added UnsafeByteOperations.unsafeWrap(byte[]) to wrap a byte array into
      ByteString without copy.

  Python
  * JSON support
    * Fixed some conformance issues.

  PHP (Alpha)
  * We have added the proto3 support for PHP via both a pure PHP package and a
    native c extension. The pure PHP package is intended to provide usability
    to wider range of PHP platforms, while the c extension is intended to
    provide higher performance. Both implementations provide the same runtime
    APIs and share the same generated code. Users don need to re-generate
    code for the same proto definition when they want to switch the
    implementation later. The pure PHP package is included in the php/src
    directory, and the c extension is included in the php/ext directory.

    Both implementations provide idiomatic PHP APIs:
    * All messages and enums are defined as PHP classes.
    * All message fields can only be accessed via getter/setter.
    * Both repeated field elements and map elements are stored in containers
      that act like a normal PHP array.

    Unlike several existing third-party PHP implementations for protobuf, our
    implementations are built on a "strongly-typed" philosophy: message fields
    and array/map containers will throw exceptions eagerly when values of the
    incorrect type (not including those that can be type converted, e.g.,
    double <-> integer <-> numeric string) are inserted.

    Currently, pure PHP runtime supports php5.5, 5.6 and 7 on linux. C
    extension runtime supports php5.5 and 5.6 on linux.

    See php/README.md for more details about installment. See
    https://developers.google.com/protocol-buffers/docs/phptutorial for more
    details about APIs.

  Objective-C
  * Helpers are now provided for working the the Any well known type (see
    GPBWellKnownTypes.h for the api additions).
  * Some improvements in startup code (especially when extensions aren used).

  Javascript
  * Fixed missing import of jspb.Map
  * Fixed valueWriterFn variable name

  Ruby
  * Fixed hash computation for JRuby's RubyMessage
  * Make sure map parsing frames are GC-rooted.
  * Added API support for well-known types.

  C#
  * Removed check on dependency in the C# reflection API.

2016-09-06 version 3.0.2 (C++/Java/Python/Ruby/Objective-C/C#/JavaScript/Lite)
  General
  * Various bug fixes.

  Objective C
  * Fix for oneofs in proto3 syntax files where fields were set to the zero
    value.
  * Fix for embedded null character in strings.
  * CocoaDocs support

  Ruby
  * Fixed memory corruption bug in parsing that could occur under GC pressure.

  Javascript
  * jspb.Map is now properly exported to CommonJS modules.

  C#
  * Removed legacy_enum_values flag.

Upgrade protobuf from 2.6.1 to 3.0.0

This version is backward compatible with proto2.

Upstream changelog:

Version 3.0.0

This change log summarizes all the changes since the last stable release
(v2.6.1). See the last section about changes since v3.0.0-beta-4.
Proto3

    Introduced Protocol Buffers language version 3 (aka proto3).

    When protocol buffers was initially open sourced it implemented Protocol
    Buffers language version 2 (aka proto2), which is why the version number
    started from v2.0.0. From v3.0.0, a new language version (proto3) is
    introduced while the old version (proto2) will continue to be supported.

    The main intent of introducing proto3 is to clean up protobuf before pushing
    the language as the foundation of Google's new API platform. In proto3, the
    language is simplified, both for ease of use and to make it available in a
    wider range of programming languages. At the same time a few features are
    added to better support common idioms found in APIs.

    The following are the main new features in language version 3:
        Removal of field presence logic for primitive value fields, removal of required fields, and removal of default values. This makes proto3 significantly easier to implement with open struct representations, as in languages like Android Java, Objective C, or Go.
        Removal of unknown fields.
        Removal of extensions, which are instead replaced by a new standard type called Any.
        Fix semantics for unknown enum values.
        Addition of maps (back-ported to proto2)
        Addition of a small set of standard types for representation of time, dynamic data, etc (back-ported to proto2)
        A well-defined encoding in JSON as an alternative to binary proto encoding.

    A new notion "syntax" is introduced to specify whether a .proto file
    uses proto2 or proto3:

    // foo.proto
    syntax = "proto3";
    message Bar {...}

    If omitted, the protocol buffer compiler generates a warning and "proto2" is
    used as the default. This warning will be turned into an error in a future
    release.

    We recommend that new Protocol Buffers users use proto3. However, we do not
    generally recommend that existing users migrate from proto2 from proto3 due
    to API incompatibility, and we will continue to support proto2 for a long
    time.

    Other significant changes in proto3.
    Explicit "optional" keyword are disallowed in proto3 syntax, as fields are optional by default; required fields are no longer supported.
    Removed non-zero default values and field presence logic for non-message fields. e.g. has_xxx() methods are removed; primitive fields set to default values (0 for numeric fields, empty for string/bytes fields) will be skipped during serialization.
    Group fields are no longer supported in proto3 syntax.
    Changed repeated primitive fields to use packed serialization by default in proto3 (implemented for C++, Java, Python in this release). The user can still disable packed serialization by setting packed to false for now.
    Added well-known type protos (any.proto, empty.proto, timestamp.proto, duration.proto, etc.). Users can import and use these protos just like regular proto files. Additional runtime support are available for each language.

    Proto3 JSON is supported in several languages (fully supported in C++, Java,
    Python and C# partially supported in Ruby). The JSON spec is defined in the
    proto3 language guide:

    https://developers.google.com/protocol-buffers/docs/proto3#json

    We will publish a more detailed spec to define the exact behavior of
    proto3-conformant JSON serializers and parsers. Until then, do not rely
    on specific behaviors of the implementation if s not documented in
    the above spec.
    Proto3 enforces strict UTF-8 checking. Parsing will fail if a string field contains non UTF-8 data.

General

    Introduced new language implementations (C#, JavaScript, Ruby, Objective-C) to proto3.

    Added support for map fields (implemented in both proto2 and proto3).
    Map fields can be declared using the following syntax:

    message Foo {
      map<string, string> values = 1;
    }

    The data of a map field is stored in memory as an unordered map and
    can be accessed through generated accessors.

    Added a "reserved" keyword in both proto2 and proto3 syntax. Users can use
    this keyword to declare reserved field numbers and names to prevent them
    from being reused by other fields in the same message.

    To reserve field numbers, add a reserved declaration in your message:

    message TestMessage {
      reserved 2, 15, 9 to 11, 3;
    }

    This reserves field numbers 2, 3, 9, 10, 11 and 15. If a user uses any of
    these as field numbers, the protocol buffer compiler will report an error.

    Field names can also be reserved:

    message TestMessage {
      reserved "foo", "bar";
    }

    Added a deterministic serialization API (currently available in C++). The deterministic serialization guarantees that given a binary, equal messages will be serialized to the same bytes. This allows applications like MapReduce to group equal messages based on the serialized bytes. The deterministic serialization is, however, NOT canonical across languages; it is also unstable across different builds with schema changes due to unknown fields. Users who need canonical serialization, e.g. persistent storage in a canonical form, fingerprinting, etc, should define their own canonicalization specification and implement the serializer using reflection APIs rather than relying on this API.
    Added a new field option "json_name". By default proto field names are converted to "lowerCamelCase" in proto3 JSON format. This option can be used to override this behavior and specify a different JSON name for the field.
    Added conformance tests to ensure implementations are following proto3 JSON specification.

C++

    Added arena allocation support (for both proto2 and proto3).

    Profiling shows memory allocation and deallocation constitutes a significant
    fraction of CPU-time spent in protobuf code and arena allocation is a
    technique introduced to reduce this cost. With arena allocation, new
    objects are allocated from a large piece of preallocated memory and
    deallocation of these objects is almost free. Early adoption shows 20% to
    50% improvement in some Google binaries.

    To enable arena support, add the following option to your .proto file:

    option cc_enable_arenas = true;

    The protocol buffer compiler will generate additional code to make the generated
    message classes work with arenas. This does not change the existing API
    of protobuf messages and does not affect wire format. Your existing code
    should continue to work after adding this option. In the future we will
    make this option enabled by default.

    To actually take advantage of arena allocation, you need to use the arena
    APIs when creating messages. A quick example of using the arena API:

    {
      google::protobuf::Arena arena;
      // Allocate a protobuf message in the arena.
      MyMessage* message = Arena::CreateMessage<MyMessage>(&arena);
      // All submessages will be allocated in the same arena.
      if (!message->ParseFromString(data)) {
        // Deal with malformed input data.
      }
      // Must not delete the message here. It will be deleted automatically
      // when the arena is destroyed.
    }

    Currently arena allocation does not work with map fields. Enabling arenas in a .proto
    file containing map fields will result in compile errors in the generated
    code. This will be addressed in a future release.

    Added runtime support for the Any type. To use Any in your proto file, first
    import the definition of Any:

    // foo.proto
    import "google/protobuf/any.proto";
    message Foo {
      google.protobuf.Any any_field = 1;
    }
    message Bar {
      int32 value = 1;
    }

    Then in C++ you can access the Any field using PackFrom()/UnpackTo()
    methods:

    Foo foo;
    Bar bar = ...;
    foo.mutable_any_field()->PackFrom(bar);
    ...
    if (foo.any_field().IsType<Bar>()) {
      foo.any_field().UnpackTo(&bar);
      ...
    }

    In text format, the entries of a map field will be sorted by key.

    Introduced new utility functions/classes in the google/protobuf/util
    directory:
        MessageDifferencer: compare two proto messages and report their differences.
        JsonUtil: support converting protobuf binary format to/from JSON.
        TimeUtil: utility functions to work with well-known types Timestamp and Duration.
        FieldMaskUtil: utility functions to work with FieldMask.

    Introduced a deterministic serialization API in
    CodedOutputStream::SetSerializationDeterministic(bool). See the notes about
    deterministic serialization in the General section.

Java

    Introduced a new util package that will be distributed as a separate
    artifact in maven. It contains:
        JsonFormat: convert proto messages to/from JSON.
        Timestamps/Durations: utility functions to work with Timestamp and Duration.
        FieldMaskUtil: utility functions to work with FieldMask.

    Introduced an ExperimentalApi annotation. Annotated APIs are experimental
    and are subject to change in a backward incompatible way in future releases.
    Introduced zero-copy serialization as an ExperimentalApi
        Introduction of the ByteOutput interface. This is similar to OutputStream but provides semantics for lazy writing (i.e. no immediate copy required) of fields that are considered to be immutable.
        ByteString now supports writing to a ByteOutput, which will directly expose the internals of the ByteString (i.e. byte[] or ByteBuffer) to the ByteOutput without copying.
        CodedOutputStream now supports writing to a ByteOutput. ByteString instances that are too large to fit in the internal buffer will be (lazily) written to the ByteOutput directly.
        This allows applications using large ByteString fields to avoid duplication of these fields entirely. Such an application can supply a ByteOutput that chains together the chunks received from CodedOutputStream before forwarding them onto the IO system.

    Other related changes to CodedOutputStream
        Additional use of sun.misc.Unsafe where possible to perform fast access to byte[] and ByteBuffer values and avoiding unnecessary range checking.
        ByteBuffer-backed CodedOutputStream now writes directly to the ByteBuffer rather than to an intermediate array.

    Performance optimizations for String fields serialization.
    The static PARSER in each generated message is deprecated, and it will be removed in a future release. A static parser() getter is generated for each message type instead.
    File option "java_generate_equals_and_hash" is now deprecated. equals() and hashCode() methods are generated by default.

Python

    Python has received several updates, most notably support for proto3
    semantics in any .proto file that declares syntax="proto3".
    Messages declared in proto3 files no longer represent field presence
    for scalar fields (number, enums, booleans, or strings). You can
    no longer call HasField() for such fields, and they are serialized
    based on whether they have a non-zero/empty/false value.

    One other notable change is in the C++-accelerated implementation.
    Descriptor objects (which describe the protobuf schema and allow
    reflection over it) are no longer duplicated between the Python
    and C++ layers. The Python descriptors are now simple wrappers
    around the C++ descriptors. This change should significantly
    reduce the memory usage of programs that use a lot of message
    types.

    Added map support.
        maps now have a dict-like interface (msg.map_field[key] = value)
        existing code that modifies maps via the repeated field interface will need to be updated.

    Added proto3 JSON format utility. It includes support for all field types and a few well-known types.
    Added runtime support for Any, Timestamp, Duration and FieldMask.
    "[ ]" is now accepted for repeated scalar fields in text format parser.
    Removed legacy Python 2.5 support.
    Moved to a single Python 2.x/3.x-compatible codebase

Ruby

    We have added proto3 support for Ruby via a native C/JRuby extension.

    For the moment we only support proto3. Proto2 support is planned, but not
    yet implemented. Proto3 JSON is supported, but the special JSON mappings
    for the well-known types are not yet implemented.

    The Ruby extension itself is included in the ruby/ directory, and details on
    building and installing the extension are in ruby/README.md. The extension
    is also be published as a Ruby gem. Code generator support is included as
    part of protoc with the --ruby_out flag.

    The Ruby extension implements a user-friendly DSL to define message types
    (also generated by the code generator from .proto files). Once a message
    type is defined, the user may create instances of the message that behave in
    ways idiomatic to Ruby. For example:
        Message fields are present as ordinary Ruby properties (getter method foo and setter method foo=).
        Repeated field elements are stored in a container that acts like a native Ruby array, and map elements are stored in a container that acts like a native Ruby hashmap.
        The usual well-known methods, such as #to_s, #dup, and the like, are present.

    Unlike several existing third-party Ruby extensions for protobuf, this
    extension is built on a "strongly-typed" philosophy: message fields and
    array/map containers will throw exceptions eagerly when values of the
    incorrect type are inserted.

    See ruby/README.md for details.

Objective-C

    Objective-C includes a code generator and a native objective-c runtime
    library. By --objc_ to protoc, the code generator will generate
    a header(.pbobjc.h) and an implementation file(.pbobjc.m) for each proto
    file.

    In this first release, the generated interface provides: enums, messages,
    field support(single, repeated, map, oneof), proto2 and proto3 syntax
    support, parsing and serialization. s compatible with ARC and non-ARC
    usage. In addition, users can access it via the swift bridging header.

C#

    C# support is derived from the project at https://github.com/jskeet/protobuf-csharp-port, which is now in maintenance mode.
    The primary differences between the previous project and the proto3 version are that message types are now mutable, and the codegen is integrated in protoc
    There are two NuGet packages: Google.Protobuf (the support library) and Google.Protobuf.Tools (containing protoc)
    Target platforms now .NET 4.5, selected portable subsets and .NET Core.
    Null values are used to represent "no value" for message type fields, and for wrapper types such as Int32Value which map to C# nullable value types.
    Proto3 semantics supported; proto2 files are prohibited for C# codegen.
    Enum values are PascalCased, and if there's a prefix which matches the name of the enum, that is removed (so an enum COLOR with a value COLOR_LIGHT_GRAY would generate a value of just LightGray).

JavaScript

    Added proto2/proto3 support for JavaScript. The runtime is written in pure JavaScript and works in browsers and in Node.js. To generate JavaScript code for your proto, invoke protoc with "--js_out". See js/README.md for more build instructions.
    JavaScript has support for binary protobuf format, but not proto3 JSON. There is also no support for reflection, since the code size impacts from this are often not the right choice for the browser.
    There is support for both CommonJS imports and Closure goog.require().

Lite

    Supported Proto3 lite-runtime in Java for mobile platforms.
    A new "lite" generator parameter was introduced in the protoc for C++ for
    Proto3 syntax messages. Example usage:

    ./protoc --cpp_out=lite:$OUTPUT_PATH foo.proto

    The protoc will treat the current input and all the transitive dependencies
    as LITE. The same generator parameter must be used to generate the
    dependencies.

    In Proto3 syntax files, "optimized_for=LITE_RUNTIME" is no longer supported.

    For Java, --javalite_out code generator is supported as a separate compiler
    plugin in a separate branch.

    Performance optimizations for Java Lite runtime on Android:
    - Reduced allocations
    - Reduced method overhead after ProGuarding
    - Reduced code size after ProGuarding
    Java Lite protos now implement deep equals/hashCode/toString

Compatibility Notice

    v3.0.0 is the first API stable release of the v3.x series. We do not expect any future API breaking changes.
    For C++, Java Lite and Objective-C, source level compatibility is guaranteed. Upgrading from v3.0.0 to newer minor version releases will be source compatible. For example, if your code compiles against protobuf v3.0.0, it will continue to compile after you upgrade protobuf library to v3.1.0.
    For other languages, both source level compatibility and binary level compatibility are guaranteed. For example, if you have a Java binary built against protobuf v3.0.0. After switching the protobuf runtime binary to v3.1.0, your built binary should continue to work.
    Compatibility is only guaranteed for documented API and documented behaviors. If you are using undocumented API (e.g., use anything in the C++ internal namespace), it can be broken by minor version releases in an undetermined manner.

Changes since v3.0.0-beta-4
Ruby

    When you assign a string field a.string_, we now call #encode(UTF-8) on the string and freeze the copy. This saves you from needing to ensure the string is already encoded as UTF-8. It also prevents you from mutating the string after it has been assigned (this is how we ensure it stays valid UTF-8).
    The generated file for foo.proto is now foo_pb.rb instead of just foo.rb. This makes it easier to see which imports/requires are from protobuf generated code, and also prevents conflicts with any foo.rb file you might have written directly in Ruby. It is a backward-incompatible change: you will need to update all of your require statements.
    For package names like foo_bar, we now translate this to the Ruby module FooBar. This is more idiomatic Ruby than what we used to do (Foo_bar).

JavaScript

    Scalar fields like numbers and boolean now return defaults instead of undefined or null when they are unset. You can test for presence explicitly by calling hasFoo(), which we now generate for scalar fields in proto2.

Java Lite

    Java Lite is now implemented as a separate plugin, maintained in the javalite branch. Both lite runtime and protoc artifacts will be available in Maven.

C#

    Target platforms now .NET 4.5, selected portable subsets and .NET Core.
    legacy_enum_values option is no longer supported.


Version 3.0.0-beta-4
General

    Added a deterministic serialization API for C++. The deterministic serialization guarantees that given a binary, equal messages will be serialized to the same bytes. This allows applications like MapReduce to group equal messages based on the serialized bytes. The deterministic serialization is, however, NOT canonical across languages; it is also unstable across different builds with schema changes due to unknown fields. Users who need canonical serialization, e.g. persistent storage in a canonical form, fingerprinting, etc, should define their own canonicalization specification and implement the serializer using reflection APIs rather than relying on this API.

    Added OneofOptions. You can now define custom options for oneof groups.

    import "google/protobuf/descriptor.proto";
    extend google.protobuf.OneofOptions {
      optional int32 my_oneof_extension = 12345;
    }
    message Foo {
      oneof oneof_group {
        (my_oneof_extension) = 54321;

    protoc is now in a separate NuGet package (Google.Protobuf.Tools)
    New option: internal_access to generate internal classes
    Enum values are now PascalCased, and if there's a prefix which matches the name of the enum, that is removed (so an enum COLOR with a value COLOR_BLUE would generate a value of just Blue).

Version 3.0.0-beta-1
Supported languages

    C++/Java/Python/Ruby/Nano/Objective-C/C#

About Beta

    This is the first beta release of protobuf v3.0.0. Not all languages have reached beta stage. Languages not marked as beta are still in alpha (i.e., be prepared for API breaking changes).

General

    Proto3 JSON is supported in several languages (fully supported in C++
    and Java, partially supported in Ruby/C#). The JSON spec is defined in
    the proto3 language guide:

    https://developers.google.com/protocol-buffers/docs/proto3#json

    We will publish a more detailed spec to define the exact behavior of
    proto3-conformant JSON serializers and parsers. Until then, do not rely
    on specific behaviors of the implementation if s not documented in
    the above spec. More specifically, the behavior is not yet finalized for
    the following:
        Parsing invalid JSON input (e.g., input with trailing commas).
        Non-camelCase names in JSON input.
        The same field appears multiple times in JSON input.
        JSON arrays  values.
        The message has unknown fields.

    Proto3 now enforces strict UTF-8 checking. Parsing will fail if a string
    field contains non UTF-8 data.

C++ (Beta)

    Introduced new utility functions/classes in the google/protobuf/util
    directory:
        MessageDifferencer: compare two proto messages and report their differences.
        JsonUtil: support converting protobuf binary format to/from JSON.
        TimeUtil: utility functions to work with well-known types Timestamp and Duration.
        FieldMaskUtil: utility functions to work with FieldMask.

    Performance optimization of arena construction and destruction.
    Bug fixes for arena and maps support.
    Changed to use cmake for Windows Visual Studio builds.
    Added Bazel support.

Java (Beta)

    Introduced a new util package that will be distributed as a separate
    artifact in maven. It contains:
        JsonFormat: convert proto messages to/from JSON.
        TimeUtil: utility functions to work with Timestamp and Duration.
        FieldMaskUtil: utility functions to work with FieldMask.

    The static PARSER in each generated message is deprecated, and it will
    be removed in a future release. A static parser() getter is generated
    for each message type instead.
    Performance optimizations for String fields serialization.
    Performance optimizations for Lite runtime on Android:
        Reduced allocations
        Reduced method overhead after ProGuarding
        Reduced code size after ProGuarding

Python (Alpha)

    Removed legacy Python 2.5 support.
    Moved to a single Python 2.x/3.x-compatible codebase, instead of using 2to3.
    Fixed build/tests on Python 2.6, 2.7, 3.3, and 3.4.
        Pure-Python works on all four.
        Python/C++ implementation works on all but 3.4, due to changes in the Python/C++ API in 3.4.
    Some preliminary work has been done to allow for multiple DescriptorPools with Python/C++.

Ruby (Alpha)

    Many bugfixes:
        fixed parsing/serialization of bytes, sint, sfixed types
        other parser bugfixes
        fixed memory leak affecting Ruby 2.2

JavaNano (Alpha)

    JavaNano generated code now will be put in a nano package by default to avoid conflicts with Java generated code.

Objective-C (Alpha)

    Added non-null markup to ObjC library. Requires SDK 8.4+ to build.
    Many bugfixes:
        Removed the class/enum filter.
        Renamed some internal types to avoid conflicts with the well-known types protos.
        Added missing support for parsing repeated primitive fields in packed or unpacked forms.
        Added *Count for repeated and map<> fields to avoid auto-create when checking for them being set.

C# (Alpha)

    Namespace changed to Google.Protobuf (and NuGet package will be named correspondingly).
    Target platforms now .NET 4.5 and selected portable subsets only.
    Removed lite runtime.
    Reimplementation to use mutable message types.
    Null references used to represent "no value" for message type fields.
    Proto3 semantics supported; proto2 files are prohibited for C# codegen. Most proto3 features supported:
        JSON formatting (a.k.a. serialization to JSON), including well-known types (except for Any).
        Wrapper types mapped to nullable value types (or string/ByteString allowing nullability). JSON parsing is not supported yet.
        maps
        oneof
        enum unknown value preservation


Version 3.0.0-alpha-3 (C++/Java/Python/Ruby/JavaNano/Objective-C/C#)
General

    Introduced two new language implementations (Objective-C, C#) to proto3.
    Explicit "optional" keyword are disallowed in proto3 syntax, as fields are optional by default.
    Group fields are no longer supported in proto3 syntax.
    Changed repeated primitive fields to use packed serialization by default in proto3 (implemented for C++, Java, Python in this release). The user can still disable packed serialization by setting packed to false for now.
    Added well-known type protos (any.proto, empty.proto, timestamp.proto, duration.proto, etc.). Users can import and use these protos just like regular proto files. Addtional runtime support will be added for them in future releases (in the form of utility helper functions, or having them replaced by language specific types in generated code).

    Added a "reserved" keyword in both proto2 and proto3 syntax. User can use
    this keyword to declare reserved field numbers and names to prevent them
    from being reused by other fields in the same message.

    To reserve field numbers, add a reserved declaration in your message:

    message TestMessage {
      reserved 2, 15, 9 to 11, 3;
    }

    This reserves field numbers 2, 3, 9, 10, 11 and 15. If a user uses any of
    these as field numbers, the protocol buffer compiler will report an error.

    Field names can also be reserved:

    message TestMessage {
      reserved "foo", "bar";
    }

    Various bug fixes since 3.0.0-alpha-2

Objective-C

    Objective-C includes a code generator and a native objective-c runtime
    library. By --objc_ to protoc, the code generator will generate
    a header(.pbobjc.h) and an implementation file(.pbobjc.m) for each proto
    file.

    In this first release, the generated interface provides: enums, messages,
    field support(single, repeated, map, oneof), proto2 and proto3 syntax
    support, parsing and serialization. s compatible with ARC and non-ARC
    usage. Besides, user can also access it via the swift bridging header.

    See objectivec/README.md for details.

C#

    C# protobufs are based on project https://github.com/jskeet/protobuf-csharp-port. The original project was frozen and all the new development will happen here.
    Codegen plugin for C# was completely rewritten to C++ and is now an intergral part of protoc.
    Some refactorings and cleanup has been applied to the C# runtime library.

    Only proto2 is supported in C# at the moment, proto3 support is in
    progress and will likely bring significant breaking changes to the API.

    See csharp/README.md for details.

C++

    Added runtime support for Any type. To use Any in your proto file, first
    import the definition of Any:

    // foo.proto
    import "google/protobuf/any.proto";
    message Foo {
      google.protobuf.Any any_field = 1;
    }
    message Bar {
      int32 value = 1;
    }

    Then in C++ you can access the Any field using PackFrom()/UnpackTo()
    methods:

    Foo foo;
    Bar bar = ...;
    foo.mutable_any_field()->PackFrom(bar);
    ...
    if (foo.any_field().IsType<Bar>()) {
      foo.any_field().UnpackTo(&bar);
      ...
    }

    In text format, entries of a map field will be sorted by key.

Java

    Continued optimizations on the lite runtime to improve performance for Android.

Python

    Added map support.
        maps now have a dict-like interface (msg.map_field[key] = value)
        existing code that modifies maps via the repeated field interface will need to be updated.

Ruby

    Improvements to RepeatedField's emulation of the Ruby Array API.
    Various speedups and internal cleanups.


Version 3.0.0-alpha-2 (C++/Java/Python/Ruby/JavaNano)
General

    Introduced Protocol Buffers language version 3 (aka proto3).

    When protobuf was initially opensourced it implemented Protocol Buffers
    language version 2 (aka proto2), which is why the version number
    started from v2.0.0. From v3.0.0, a new language version (proto3) is
    introduced while the old version (proto2) will continue to be supported.

    The main intent of introducing proto3 is to clean up protobuf before
    pushing the language as the foundation of Google's new API platform.
    In proto3, the language is simplified, both for ease of use and to
    make it available in a wider range of programming languages. At the
    same time a few features are added to better support common idioms
    found in APIs.

    The following are the main new features in language version 3:
        Removal of field presence logic for primitive value fields, removal of required fields, and removal of default values. This makes proto3 significantly easier to implement with open struct representations, as in languages like Android Java, Objective C, or Go.
        Removal of unknown fields.
        Removal of extensions, which are instead replaced by a new standard type called Any.
        Fix semantics for unknown enum values.
        Addition of maps.
        Addition of a small set of standard types for representation of time, dynamic data, etc.
        A well-defined encoding in JSON as an alternative to binary proto encoding.

    This release (v3.0.0-alpha-2) includes partial proto3 support for C++,
    Java, Python, Ruby and JavaNano. Items 6 (well-known types) and 7
    (JSON format) in the above feature list are not implemented.

    A new notion "syntax" is introduced to specify whether a .proto file
    uses proto2 or proto3:

    // foo.proto
    syntax = "proto3";
    message Bar {...}

    If omitted, the protocol compiler will generate a warning and "proto2" will
    be used as the default. This warning will be turned into an error in a
    future release.

    We recommend that new Protocol Buffers users use proto3. However, we do not
    generally recommend that existing users migrate from proto2 from proto3 due
    to API incompatibility, and we will continue to support proto2 for a long
    time.

    Added support for map fields (implemented in proto2 and proto3 C++/Java/JavaNano and proto3 Ruby).

    Map fields can be declared using the following syntax:

    message Foo {
      map<string, string> values = 1;
    }

    Data of a map field will be stored in memory as an unordered map and it
    can be accessed through generated accessors.

C++

    Added arena allocation support (for both proto2 and proto3).

    Profiling shows memory allocation and deallocation constitutes a significant
    fraction of CPU-time spent in protobuf code and arena allocation is a
    technique introduced to reduce this cost. With arena allocation, new
    objects will be allocated from a large piece of preallocated memory and
    deallocation of these objects is almost free. Early adoption shows 20% to
    50% improvement in some Google binaries.

    To enable arena support, add the following option to your .proto file:

    option cc_enable_arenas = true;

    Protocol compiler will generate additional code to make the generated
    message classes work with arenas. This does not change the existing API
    of protobuf messages and does not affect wire format. Your existing code
    should continue to work after adding this option. In the future we will
    make this option enabled by default.

    To actually take advantage of arena allocation, you need to use the arena
    APIs when creating messages. A quick example of using the arena API:

    {
      google::protobuf::Arena arena;
      // Allocate a protobuf message in the arena.
      MyMessage* message = Arena::CreateMessage<MyMessage>(&arena);
      // All submessages will be allocated in the same arena.
      if (!message->ParseFromString(data)) {
        // Deal with malformed input data.
      }
      // Must not delete the message here. It will be deleted automatically
      // when the arena is destroyed.
    }

    Currently arena does not work with map fields. Enabling arena in a .proto
    file containing map fields will result in compile errors in the generated
    code. This will be addressed in a future release.

Python

    Python has received several updates, most notably support for proto3
    semantics in any .proto file that declares syntax="proto3".
    Messages declared in proto3 files no longer represent field presence
    for scalar fields (number, enums, booleans, or strings). You can
    no longer call HasField() for such fields, and they are serialized
    based on whether they have a non-zero/empty/false value.

    One other notable change is in the C++-accelerated implementation.
    Descriptor objects (which describe the protobuf schema and allow
    reflection over it) are no longer duplicated between the Python
    and C++ layers. The Python descriptors are now simple wrappers
    around the C++ descriptors. This change should significantly
    reduce the memory usage of programs that use a lot of message
    types.

Ruby

    We have added proto3 support for Ruby via a native C extension.

    The Ruby extension itself is included in the ruby/ directory, and details on
    building and installing the extension are in ruby/README.md. The extension
    will also be published as a Ruby gem. Code generator support is included as
    part of protoc with the --ruby_out flag.

    The Ruby extension implements a user-friendly DSL to define message types
    (also generated by the code generator from .proto files). Once a message
    type is defined, the user may create instances of the message that behave in
    ways idiomatic to Ruby. For example:
        Message fields are present as ordinary Ruby properties (getter method foo and setter method foo=).
        Repeated field elements are stored in a container that acts like a native Ruby array, and map elements are stored in a container that acts like a native Ruby hashmap.
        The usual well-known methods, such as #to_s, #dup, and the like, are present.

    Unlike several existing third-party Ruby extensions for protobuf, this
    extension is built on a "strongly-typed" philosophy: message fields and
    array/map containers will throw exceptions eagerly when values of the
    incorrect type are inserted.

    See ruby/README.md for details.

JavaNano

    JavaNano is a special code generator and runtime library designed especially
    for resource-restricted systems, like Android. It is very resource-friendly
    in both the amount of code and the runtime overhead. Here is an an overview
    of JavaNano features compared with the official Java protobuf:
        No descriptors or message builders.
        All messages are mutable; fields are public Java fields.
        For optional fields only, encapsulation behind setter/getter/hazzer/ clearer functions is opt-in, which provide proper 'has' state support.
        For proto2, if not opted in, has state (field presence) is not available. Serialization outputs all fields not equal to their defaults. The behavior is consistent with proto3 semantics.
        Required fields (proto2 only) are always serialized.
        Enum constants are integers; protection against invalid values only when parsing from the wire.
        Enum constants can be generated into container interfaces bearing the enum's name (so the referencing code is in Java style).
        CodedInputByteBufferNano can only take byte.
        Similarly CodedOutputByteBufferNano can only write to byte[].
        Repeated fields are in arrays, not ArrayList or Vector. Null array elements are allowed and silently ignored.
        Full support for serializing/deserializing repeated packed fields.
        Support extensions (in proto2).
        Unset messages/groups are null, not an immutable empty default instance.
        toByteArray(...) and mergeFrom(...) are now static functions of MessageNano.
        The 'bytes' type translates to the Java type byte[].

    See javanano/README.txt for details.


Version 3.0.0-alpha-1 (C++/Java)

    list are not impelmented.

    A new notion "syntax" is introduced to specify whether a .proto file
    uses proto2 or proto3:

    // foo.proto
    syntax = "proto3";
    message Bar {...}

    If omitted, the protocol compiler will generate a warning and "proto2" will
    be used as the default. This warning will be turned into an error in a

    generally recommend that existing users migrate from proto2 from proto3 due
    to API incompatibility, and we will continue to support proto2 for a long
    time.

    Added support for map fields (implemented in C++/Java for both proto2 and
    proto3).

    Map fields can be declared using the following syntax:

    message Foo {
      map<string, string> values = 1;
    }

    Data of a map field will be stored in memory as an unordered map and it
    can be accessed through generated accessors.

    APIs when creating messages. A quick example of using the arena API:

    {
      google::protobuf::Arena arena;
      // Allocate a protobuf message in the arena.
      MyMessage* message = Arena::CreateMessage<MyMessage>(&arena);
      // All submessages will be allocated in the same arena.
      if (!message->ParseFromString(data)) {
        // Deal with malformed input data.
      }
      // Must not delete the message here. It will be deleted automatically
      // when the arena is destroyed.
    }

    Currently arena does not work with map fields. Enabling arena in a .proto
    file containing map fields will result in compile errors in the generated
    code. This will be addressed in a future release.

Update protobuf to 2.6.1

Changelog:

2014-10-20 version 2.6.1:

  C++
  * Added atomicops support for Solaris.
  * Released memory allocated by InitializeDefaultRepeatedFields() and
    GetEmptyString(). Some memory sanitizers reported them as memory leaks.

  Java
  * Updated DynamicMessage.setField() to handle repeated enum values
    correctly.
  * Fixed a bug that caused NullPointerException to be thrown when
    converting manually constructed FileDescriptorProto to
    FileDescriptor.

  Python
  * Fixed WhichOneof() to work with de-serialized protobuf messages.
  * Fixed a missing file problem of Python C++ implementation.

2014-08-15 version 2.6.0:

  General
  * Added oneofs(unions) feature. Fields in the same oneof will share
    memory and at most one field can be set at the same time. Use the
    oneof keyword to define a oneof like:
      message SampleMessage {
        oneof test_oneof {
          string name = 4;
          YourMessage sub_message = 9;
        }
      }
  * Files, services, enums, messages, methods and enum values can be marked
    as deprecated now.
  * Added Support for list values, including lists of mesaages, when
    parsing text-formatted protos in C++ and Java.
      For example:  foo: [1, 2, 3]

  C++
  * Enhanced customization on TestFormat printing.
  * Added SwapFields() in reflection API to swap a subset of fields.
    Added SetAllocatedMessage() in reflection API.
  * Repeated primitive extensions are now packable. The
    [packed=true] option only affects serializers. Therefore, it is
    possible to switch a repeated extension field to packed format
    without breaking backwards-compatibility.
  * Various speed optimizations.

  Java
  * writeTo() method in ByteString can now write a substring to an
    output stream. Added endWith() method for ByteString.
  * ByteString and ByteBuffer are now supported in CodedInputStream
    and CodedOutputStream.
  * java_generate_equals_and_hash can now be used with the LITE_RUNTIME.

  Python
  * A new C++-backed extension module (aka "cpp api v2") that replaces the
    old ("cpp api v1") one.  Much faster than the pure Python code.  This one
    resolves many bugs and is recommended for general use over the
    pure Python when possible.
  * Descriptors now have enum_types_by_name and extension_types_by_name dict
    attributes.
  * Support for Python 3.

Update to 2.5.0:

2013-02-27 version 2.5.0:

  General
  * New notion "import public" that allows a proto file to forward the content
    it imports to its importers. For example,
      // foo.proto
      import public "bar.proto";
      import "baz.proto";

      // qux.proto
      import "foo.proto";
      // Stuff defined in bar.proto may be used in this file, but stuff from
      // baz.proto may NOT be used without importing it explicitly.
    This is useful for moving proto files. To move a proto file, just leave
    a single "import public" in the old proto file.
  * New enum option "allow_alias" that specifies whether different symbols can
    be assigned the same numeric value. Default value is "true". Setting it to
    false causes the compiler to reject enum definitions where multiple symbols
    have the same numeric value.

  C++
  * New generated method set_allocated_foo(Type* foo) for message and string
    fields. This method allows you to set the field to a pre-allocated object
    and the containing message takes the ownership of that object.
  * Added SetAllocatedExtension() and ReleaseExtension() to extensions API.
  * Custom options are now formatted correctly when descriptors are printed in
    text format.
  * Various speed optimizations.

  Java
  * Comments in proto files are now collected and put into generated code as
    comments for corresponding classes and data members.
  * Added Parser to parse directly into messages without a Builder. For
    example,
      Foo foo = Foo.getParser().ParseFrom(input);
    Using Parser is ~25% faster than using Builder to parse messages.
  * Added getters/setters to access the underlying ByteString of a string field
    directly.
  * ByteString now supports more operations: substring(), prepend(), and
    append(). The implementation of ByteString uses a binary tree structure
    to support these operations efficiently.
  * New method findInitializationErrors() that lists all missing required
    fields.

  * Unknown fields are now preserved after parsing.
  * Fixed bug where custom options were not correctly populated. Custom
