Sometimes it is helpful to know what the differences between releases of Tcl/Tk are. Perhaps you want to know how many releases back a feature is available. Perhaps you want to know "What's new?" since your reference book was published. These pages aim to quickly summarize the differences introduced in each release of Tcl/Tk which are visible at the script level. For further details, see the ''changes'' file in the Tcl/Tk distribution [http://core.tcl.tk/tcl/finfo?name=changes&n=10][http://core.tcl.tk/tk/finfo?name=changes&n=10]. **Tcl/Tk 9.0** * [Changes in Tcl/Tk 9.0] — '''2024'''-01-05 **Tcl/Tk 8.6** * [Changes in Tcl/Tk 8.6.14] — '''2024'''-02-28 * [Changes in Tcl/Tk 8.6.13] — '''2022'''-11-22 * [Changes in Tcl/Tk 8.6.12] — '''2021'''-11-05 * [Changes in Tcl/Tk 8.6.11] — '''2020'''-12-31 * [Changes in Tcl/Tk 8.6.10] — '''2019'''-11-21 * [Changes in Tcl/Tk 8.6.9] — '''2018'''-11-16 * [Changes in Tcl/Tk 8.6.8] — 2017-12-22 * [Changes in Tcl/Tk 8.6.7] — '''2017'''-08-09 * [Changes in Tcl/Tk 8.6.6] — 2016-07-27 * [Changes in Tcl/Tk 8.6.5] — '''2016'''-02-29 * [Changes in Tcl/Tk 8.6.4] — '''2015'''-03-12 * [Changes in Tcl/Tk 8.6.3] — 2014-11-12 * [Changes in Tcl/Tk 8.6.2] — '''2014'''-08-27 * [Changes in Tcl/Tk 8.6.1] — 2013-09-20 * [Changes in Tcl/Tk 8.6%|%Changes in Tcl/Tk 8.6.0] — 2012-12-20 **Tcl/Tk 8.5** * [Changes in Tcl/Tk 8.5.19] — '''2016'''-02-12 * [Changes in Tcl/Tk 8.5.18] — '''2015'''-03-06 * [Changes in Tcl/Tk 8.5.17] — 2014-10-25 * [Changes in Tcl/Tk 8.5.16] — '''2014'''-08-25 * [Changes in Tcl/Tk 8.5.15] — 2013-09-18 * [Changes in Tcl/Tk 8.5.14] — '''2013'''-04-03 * [Changes in Tcl/Tk 8.5.13] — 2012-11-12 * [Changes in Tcl/Tk 8.5.12] — '''2012'''-07-27 * [Changes in Tcl/Tk 8.5.11] — 2011-11-04 * [Changes in Tcl/Tk 8.5.10] — '''2011'''-06-24 * [Changes in Tcl/Tk 8.5.9] — '''2010'''-09-08 * [Changes in Tcl/Tk 8.5.8] — 2009-11-16 * [Changes in Tcl/Tk 8.5.7] — '''2009'''-04-15 * [Changes in Tcl/Tk 8.5.6] — 2008-12-23 * [Changes in Tcl/Tk 8.5.5] — 2008-10-15 * [Changes in Tcl/Tk 8.5.4] — 2008-08-15 * [Changes in Tcl/Tk 8.5.3] — 2008-06-30 * [Changes in Tcl/Tk 8.5.2] — 2008-03-28 * [Changes in Tcl/Tk 8.5.1] — '''2008'''-02-05 * [Changes in Tcl/Tk 8.5] — 2007-12-20 **Tcl/Tk 8.4** * [Changes in Tcl/Tk 8.4.20] — '''2013'''-06-01 * [Changes in Tcl/Tk 8.4.19] — 2008-04-18 * [Changes in Tcl/Tk 8.4.18] — 2008-02-08 * [Changes in Tcl/Tk 8.4.17] — '''2008'''-01-04 * [Changes in Tcl/Tk 8.4.16] — 2007-09-21 * [Changes in Tcl/Tk 8.4.15] — '''2007'''-05-25 * [Changes in Tcl/Tk 8.4.14] — 2006-10-19 * [Changes in Tcl/Tk 8.4.13] — '''2006'''-04-19 * [Changes in Tcl/Tk 8.4.12] — 2005-12-03 * [Changes in Tcl/Tk 8.4.11] — 2005-06-28 * [Changes in Tcl/Tk 8.4.10] — '''2005'''-06-04 * [Changes in Tcl/Tk 8.4.9] — 2004-12-07 * [Changes in Tcl/Tk 8.4.8] — 2004-11-22 * [Changes in Tcl/Tk 8.4.7] — 2004-07-25 * [Changes in Tcl/Tk 8.4.6] — '''2004'''-03-01 * [Changes in Tcl/Tk 8.4.5] — 2003-11-24 * [Changes in Tcl/Tk 8.4.4] — 2003-07-22 * [Changes in Tcl/Tk 8.4.3] — 2003-05-19 * [Changes in Tcl/Tk 8.4.2] — '''2003'''-03-03 * [Changes in Tcl/Tk 8.4.1] — 2002-10-22 * [Changes in Tcl/Tk 8.4] — 2002-09-10 **Tcl/Tk 8.3** * [Changes in Tcl/Tk 8.3.5] — '''2002'''-10-18 * [Changes in Tcl/Tk 8.3.4] — 2001-10-19 * [Changes in Tcl/Tk 8.3.3] — '''2001'''-04-06 * [Changes in Tcl/Tk 8.3.2] — 2000-08-09 * [Changes in Tcl/Tk 8.3.1] — 2000-04-26 * [Changes in Tcl/Tk 8.3] — '''2000'''-02-10 **Tcl/Tk 8.2** * [Changes in Tcl/Tk 8.2.3] — 1999-12-16 * [Changes in Tcl/Tk 8.2.2] — 1999-11-04 * [Changes in Tcl/Tk 8.2.1] — 1999-10-04 * [Changes in Tcl/Tk 8.2.0] — 1999-08-17 **Tcl/Tk 8.1** * [Changes in Tcl/Tk 8.1.1] — 1999-05-25 * [Changes in Tcl/Tk 8.1] — 1999-04-29 **Tcl/Tk 8.0** * [Changes in Tcl/Tk 8.0.5] — '''1999'''-03-09 * [Changes in Tcl/Tk 8.0.4] — 1998-11-19 * [Changes in Tcl/Tk 8.0.3] — '''1998'''-08-10 * [Changes in Tcl/Tk 8.0p2] — 1997-11-25 ??? * [Changes in Tcl/Tk 8.0p1] — 1997-11-07 * [Changes in Tcl/Tk 8.0] — '''1997'''-08-18 **Tcl/Tk 7** * [Changes in Tcl/Tk 7.6/4.2] — 1996-10-16 * [Changes in Tcl/Tk 7.5/4.1] — '''1996'''-04-21 * … * [Tcl 2.1] — '''1990'''-03-03 ---- [Donald Porter] ----- Commentary on individual changes also appears in "[Advantages and disadvantages of different Tcl versions]".
