Summary of Changes since Tcl/Tk 8.5:

The following were the main changes in Tcl/Tk 8.6a1. A complete list
can be found in the changes file at the root of the source tree. The
more complete ChangeLog is also included with each source release.

This release is the first alpha release of 8.6. The alpha moniker means
that it is in feature addition mode. All bug fixes (and some more) up
to and including 8.5.3 changes are included in 8.6a1. The following
list focuses on new features added so far in 8.6. This release is a
development release, and should only be considered for deployment use
after considerable testing.

* [TIP 257] New commands [oo::object], [oo::class], etc. support object
oriented programming.

* [TIP 230] New commands [chan push] and [chan pop] provide script-level
access to the stacked channels mechanism.

* [TIP 285] New routines Tcl_CancelEval() and Tcl_Canceled() to
allow interruption of script evaluation in an interp by the embedding

* [TIP 317] New commands [binary encode] and [binary decode].

* [binary] is now a [namespace ensemble].

* [uplevel $l $script] now bytecompiles $script.

* C code compiled with USE_TCL_STUBS now must be linked against a
stub library. The Tcl shared library no longer exports variables
used in the stub interface. Analogous changes also made to Tk.

* New visual-styles element engine for Tk on Windows.

* Writing GIF images now uses real LZW compression.

仮想化がメインストリームな事を考えると、昔ほど Wine の必要性は高くないかも。
Wine じゃなきゃ困るのってどんな状況?

とありましたが、Linux 上でクロスコンパイルした Windows バイナリの最初の動作確認をする場合に、とても重宝しています。
ちなみに Fedora ではまだ 1.0-0.3.rc3 です。
