* XEmacs 21.5.35 "kohlrabi" is released.
"kohlrabi" is the thirty-sixth in the VEGETABLE series.
This release is the first beta release since 2013. The most important change included is a merge of Ben Wing’s work providing Unicode as an internal format.
The bulk of this work was done coming up to 2010 and it was merged to the trunk in 2016. To enable it, pass --with-unicode-internal to the configure script.
Important other changes are Jeff Sparke’s work updating the GTK support to handle GTK3, Jerry James’ work to add transport level security (TLS, including
SSL) support to the network code, Aidan Kehoe’s to improve algorithmic complexity problems related to use of character positions in C code, Jaakko Salomaa’s work to support the OpenSSL bignum implementation, work from multiple
people to have XEmacs build on 64-bit Windows.
Changes to improve maintainability include removal of support for Windows 95/98/ME, removal of support for unexec, removal of support for incremental garbage collection (slower, more memory-intensive, and buggier than the alternative), removal of support for non-KKCC memory descriptions (KKCC was done as part of the incremental GC work, but is stable, fast and reliable), removal of several redundant C-level hash table implementations, moving many non-hotspot functions from C to Lisp.
This is the development line. The current series started with XEmacs
21.5.0 (an alias for XEmacs 21.4.0 "Solid Vapor", the first release in
the current stable line). 21.5 is the code base for introduction of
major new subsystems and fixes to design bugs that experience shows will introduce instability. So far the main effort has been on improved
support for Unicode, updates to the build infrastructure, and development
of new features in memory allocation.

community, see our home page,

* XEmacs 21.5.35 is "beta" software.
The usual "no warranty" disclaimer (see etc/COPYING, sections 10 and 11) applies. At this point in time, it is the version that most developers
are using for their daily work. However, it is certain that many bugs
remain and new ones will be introduced as development proceeds. Be sure
to take care to save your work often and follow a regular backup regime.
