9 What the Future Holds

This is part 9 of the XEmacs Frequently Asked Questions list. This section will change frequently, and (in theory) should contain any interesting items that have transpired recently. (But in practice it’s not getting updated like this.)

This section also contains descriptions of the new features in all the recent releases of XEmacs. For the most part, the information below is a synopsis of the more complete information that can be found in the file ‘NEWS’ in the ‘etc’ directory of the XEmacs distribution. You can view this file in XEmacs using C-h n or the ‘Help’ menu.

Information on older versions of XEmacs can be find in ‘ONEWS’ in the same directory, or ‘OONEWS’ for really old versions.

Q9.0.2: What’s new in XEmacs 21.4?

21.4 was the "stable" version of the 21.2 series, which was considered "experimental" throughout its life; thus there were no "official" releases at all. In essence, XEmacs is now following the "alternating" scheme of Linux, where at any point there are at least two different development branches, one "stable" and one "experimental". Periodic releases happen in both branches, but those in the experimental branch are not tested as well, and there’s no guarantee they will work at all. The experimental branch is open to any and all code that’s acceptable to the developers; the stable branch, however, is in general limited only to bug fixes, and all contributions are carefully reviewed to make sure they will increase and not decrease stability.

21.3 never existed at all; it was decided to follow the Linux scheme exactly, where odd-numbered series are experimental and even-numbered ones stable.

The following lists summarizes the essential changes made in this version. For a fuller list, see the ‘NEWS’ in the ‘etc’ directory of the XEmacs distribution, or use C-h n or the ‘Help’ menu to view this file inside of XEmacs.

Q9.0.5: What’s new in XEmacs 20.3?

XEmacs 20.3 was released in November 1997. It contains many bugfixes, and a number of new features, including Autoconf 2 based configuration, additional support for Mule (Multi-language extensions to Emacs), many more customizations, multiple frames on TTY-s, support for multiple info directories, an enhanced gnuclient, improvements to regexp matching, increased MIME support, and many, many synches with GNU Emacs 20.

The XEmacs/Mule support has been only seriously tested in a Japanese locale, and no doubt many problems still remain. The support for ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a price—about a 30% slowdown from 19.16. We’re making progress on improving performance and XEmacs 20.3 compiled without Mule (which is the default) is definitely faster than XEmacs 19.16.

XEmacs 20.3 is the first non-beta v20 release, and will be the basis for all further development.

Q9.0.6: What’s new in XEmacs 20.2?

The biggest changes in 20.2 include integration of EFS (the next generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a major mode for editing Tex and LaTeX, and a lot of other stuff). Many bugs from 20.0 have been fixed for this release. 20.2 also contains a new system for customizing XEmacs options, invoked via M-x customize.

XEmacs 20.2 is the development release (20.0 was beta), and is no longer considered unstable.

For older news, see the file ‘ONEWS’ in the ‘etc’ directory of the XEmacs distribution.
