(Copied from the Internals Manual, where the canonical version lives.)

More information about history can be found in the beginning of the Internals Manual and in the About page. -- A time line for Lucid Emacs/XEmacs is Version 19.0 shipped with Energize 1.0, April 1992. Version 19.1 released June 4, 1992. Version 19.2 released June 19, 1992. Version 19.3 released September 9, 1992. Version 19.4 released January 21, 1993. Version 19.5 released February 5, 1993. This was a repackaging of 19.4 with a few bug fixes and shipped with Energize 2.0. It was a trade-show giveaway and never released to the net. Version 19.6 released April 9, 1993. Version 19.7 was a repackaging of 19.6 with a few bug fixes and shipped with Energize 2.1. Never released to the net. Version 19.8 released September 6, 1993. (Epoch merger, preliminary I18N support) Version 19.9 released January 12, 1994. (Scrollbars, Athena.) Version 19.10 released May 27, 1994. Known as "Lucid Emacs" when shipped by Lucid, and as "XEmacs" when shipped by Sun; but Lucid went out of business a few days later and it's unclear very many copies of 19.10 were released by Lucid. (Last release by Jamie Zawinski.) Version 19.11 (first XEmacs) released September 13, 1994. Version 19.12 released June 23, 1995. Version 19.13 released September 1, 1995. Version 19.14 released June 23, 1996. Version 20.0 released February 9, 1997. Version 19.15 released March 28, 1997. Version 20.1 (not released to the net) April 15, 1997. Version 20.2 released May 16, 1997. Version 19.16 released October 31, 1997; retiring of v19 series. Version 20.3 (the first stable version of XEmacs 20.x) released November 30, 1997. Version 20.4 released February 28, 1998. (Jamie claims this version is the "first reasonably stable release with MULE support" and says that "XEmacs 'core' and 'packages' now packaged separately.") Version 21.0-pre5 released July 18, 1998. (Jamie says "Numbering scheme goes wonky due to switch to stable + unstable branches.") Version 21.0.60 released December 10, 1998. (The version naming scheme was changed at this point: [a] the second version number is odd for stable versions, even for beta versions; [b] a third version number is added, replacing the "beta xxx" ending for beta versions and allowing for periodic maintenance releases for stable versions. Therefore, 21.0 was never "officially" released; similarly for 21.2, etc.) Version 21.0.61 released January 4, 1999. Version 21.0.63 released February 3, 1999. Version 21.0.64 released March 1, 1999. Version 21.0.65 released March 5, 1999. Version 21.0.66 released March 12, 1999. Version 21.0.67 released March 25, 1999. Version 21.1.2 released May 14, 1999; on comp.emacs, May 28. (This is the followup to 21.0.67. The second version number was bumped to indicate the beginning of the "stable" series.) Version 21.1.3 released June 26, 1999. Version 21.1.4 released July 8, 1999. Version 21.1.6 released August 14, 1999. (There was no 21.1.5.) Version 21.1.7 released September 26, 1999. Version 21.1.8 released November 2, 1999. Version 21.1.9 released February 13, 2000.
