8.5 の次は 8.6 らしい

Tcl/Tk 8.5.0 がリリースされてまだ日が浅いのですが、新しい年を迎え、今年のリリーススケジュール案が Don Porter 氏から発表されました。とりあえず、近日中に Tcl/Tk 8.4.17 がリリースされるようです。既に RC 版が出ています。２月には Tcl/Tk 8.5.1 がリリースされる予定。

なお、8.5 の次のバージョンは 8.6 になるみたいです。随分昔の話になりますが、8.5 の CVS ブランチを作る際に、9.0 にした方が良いのではないかという話で盛り上がったのですが、今回はすんなりと 8.6 になりそうな雰囲気です。ま、どうなるかわかりませんけれども…。

計画通りに開発が進めばバージョン 8.5 は短命になりますが、この手のスケジュールは遅れるのが常です。

Subject: [TCLCORE] Draft Release Calendar for 2008

Here is my current thinking about release dates in 2008.

January 4, 2008  Tcl/Tk 8.4.17

 Get the current set of 8.4 bug fixes out in a release.

February 1, 2008 Tcl/Tk 8.5.1

March 14, 2008  Tcl/Tk 8.4.18; Tcl/Tk 8.5.2; Tcl/Tk 8.6a0

 Intent is for 8.4.18 to be the "final" release of Tcl/Tk 8.4.
 Any lingering bugs needing fixing... someone should get busy
 doing so by then, or get resigned to living with them for good.

 The 8.5.2 and 8.6a0 releases are intended to be exactly the
 same code, with version number being the only difference.
 The development point right between the two releases is the
 point where the HEAD will become devoted to 8.6 development,
 and a new branch, core-8-5-branch will spawn to generate further
 8.5.* patch releases.

May 16, 2008  Tcl/Tk 8.6a1; Tcl/Tk 8.5.3

July 18, 2008  Tcl/Tk 8.6a2; Tcl/Tk 8.5.4

Sept. 19, 2008  Tcl/Tk 8.6b1; Tcl/Tk 8.5.5

This gets us to beta status for Tcl/Tk 8.6 right in time for
the 2008 Tcl Conference (Sept. 22-26, 2008).  The schedule
for 8.5.* patch releases proposed here is a minimum.  More
frequent patch releases might happen if number/severity of
bug fixes warrants.

In some circles, a full year of development time to get to 8.6 beta
might seem sluggish, but in context of our history, this is a pretty
aggressive schedule.

This schedule offers three target dates for new features in Tcl/Tk 8.6.
If the shouts of protest aren't too loud, what I'd like to do next is
place the proposed 8.6[ab]* release dates on the "Tcl 8.6 Wish List"
page on the Wiki <URL: http://wiki.tcl.tk/20539 > and invite developers
to place their desired features under one of the target dates, and to
name some person(s) actively working to get that feature ready by that
date.

All of this is subject to revision, based on your comments.
