*          XEmacs 21.4.25 "Too Much Mozart" is released.
      "Two Much Mozart" is the twenty-sixth in the OXYMORON series.

This is a limited-functionality release to fix a longstanding bug in the byte
compiler that does not actually cause problems for 21.4, but does cause
problems for 21.5, which uses the same packages.  XEmacs 21.4 is, in theory,
the stable release of XEmacs, but it has significant limitations in its Unicode
support, among many other features and is unlikely to be the best choice of
editor for the user.

Other changes are courtesy of Hauke Fath and the NetBSD pkgsrc.

This is the stable line.  The current series started with XEmacs
XEmacs 21.4.0 "Solid Vapor".  21.5 is the code base for introduction of
major new subsystems and fixes to design bugs that experience shows will
introduce instability and is maintained separately.
