Changes 8.6.7: Bug fixes.
Export TDBC_VERSION like ITCL_VERSION. Use these versions as well in Makefile and PLIST. It's unclear whether buildlink3.mk might include Makefile.version, this is the reason to duplicate this information. There are other packages that might be versioned similarily: - sqlite3, - thread. No user-visible change in the main package.
Provide bundled itcl version (ITCL_VERSION) in buildlink3.mk Packages need to know files with ITCL of current TCL version.
Changes 8.6.6: Bug-fix release.
Changes 8.6.5: Bug fixes.
Fix build of tcl-pdflib against TCL 8.6.
Changes 8.6.4: Bug fixes and improvements.
Changes 8.6.3:
Correct Method Search Order
Regression [lreplace {} 1 1]
Crash regression in [oo::class destroy]
Regress [regsub -all {\(.*} a(b) {}]
[try {} on ok {} - on return {} {}] panic
[tcl::unsupported::getbytecode] disassember
[string cat] bytecode optimization
segfault in mangled bytecode
Hang in some [read]s of limited size
segfault in [array set] of traced array
MSVC14 compile support
[fcopy] treats [blocked] as error
regression in Tcl_Write() interface
fix [gets] on non-blocking channels
restore [open comX: r+]
Restore [lappend v] return value
Stop forcing EOF to be permanent
Changes 8.6.2: This is a bug-fix release.
Changes 8.6.1: * object-oriented programming support * a stackless evaluation implementation and much more besides.
Changes 8.5.15: Bug-fix release.
Changes 8.5.14: Bug-fix release.
Changes 8.5.13: * --enable-aqua build for Mac OS X is now a Cocoa implementation. * Support has been added for Cygwin network pathnames. * Updated to Unicode 6.2 support. Fixes for several crashes and bugs.
lang/tcl: Upgrade from version 8.4.18 to 8.5.12
Highlights of Tcl 8.5
* Features: 8.5 has over 90 TIPs included to provide a wide variety of
new features.
* Bignums: Tcl now supports arbitrary-precision integers, which improves
math operations on large integers.
* Safer interps: Tcl's powerful safe interpreter mechanism now has
improved control of time and command limits in slave interpreters.
* clock command: More robust implementation of command for specifying
time, with significant l10n and i18n improvements.
* dict command: New data structure that allows access to data by value
rather than a variable name, which is substantially faster.
* Additional improvements: Faster list search, new and improved
mathematics procedures, anonymous procedures, new ways to package Tcl
extensions, Tcl-level custom channel types, file and line location
information for each command, and more.
There is of course much, much more.
See [8.5 Changes](http://wiki.tcl.tk/10630) on the wiki for a complete
list of new features.
