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.

* --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.
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.
* generic/tclInterp.c (Tcl_GetAlias): fix for [Bug 1882373]
* generic/regguts.h, generic/regc_color.c, generic/regc_nfa.c:
Fixes for problems created when processing regular expressions that
generate very large automata. An enormous number of thanks to Will
Drewry <wad@google.com>, Tavis Ormandy <taviso@google.com>, and Tom
Lane <tgl@sss.pgh.pa.us> from the Postgresql crowd for their help in
tracking these problems down. [Bug 1810264]
* unix/tclUnixCompat.c (TclpGetHostByName): Really applied
the change noted on 2007-11-13 by dkf below.
* generic/tclIOUtil.c (TclGetOpenMode): Only set the O_APPEND flag
* tests/ioUtil.test (ioUtil-4.1): on a channel for the 'a'
mode and not for 'a+'. [Bug 1773127] (backport from HEAD)
* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Prevent shimmering crash
when -exact and -integer/-real are mixed. [Bug 1844789]
* generic/tclThread.c: Back-port locking changes from Tcl8.5
in Tcl_Mutex/ConditionFinlize. Now we properly master-lock
the finalization of sync primitives.
* generic/regc_nfa.c: Fixed infinite loop in the regexp compiler
* generic/regcomp.c: [Bug 1810038]. Corrected looping logic in
* tests/regexp.test: fixempties() to avoid wasting time walking a
list of dead states [Bug 1832612]. Convert optst() from expensive
no-op to a cheap no-op. Improve newline usage in debug output.
* unix/tclUnixCompat.c (TclpGetHostByName): The six-argument form of
getaddressbyname_r() uses the fifth argument to indicate whether the
lookup succeeded or not on at least one platform. [Bug 1618235]
* generic/regc_lex.c (lexescape): Ensure that backreference numbers
can't overflow a signed int in a way that breaks things. [Bug 1810264]
* generic/tclParse.c (Tcl_ParseBraces): fix for possible read
after the end of buffer, [Bug 1813528] (Joe Mistachkin).
* generic/tclObj.c (Tcl_FindCommandFromObj): fix finding a deleted
command; cannot trigger this from Tcl itself, but crash reported
on xotcl. This check is new to 8.4 but exists in 8.5, so this is a
backport or something. Thanks Gustaf Neumann.
* generic/tcl.h (Tcl_DecrRefCount): Update change from 2006-05-29
to make macro more warning-robust in unbraced if code.
* Tk_PhotoPutBlock performance restored (JPEG image loading).
