XEmacs 19.15 is intended to be a stable release and good for however
long it takes for XEmacs v20 to stabilize.  In terms of package
features 19.15 and 20.1 will be roughly equivalent.

The primary new feature in 20.0 is the MULE support, but it comes at a
price -- about a 30% slowdown from 19.14.  We're working on making
things faster, but it's taking time.  Currently, 19.15 and 20.0
compiled with MULE (20.0-latin-1) are somewhat faster than 19.14.

With patches I integrated this morning from Joe Nuspl, my main
objection to 19.15 last November has been cancelled, as 19.15 now has
all the maintenance work done on the 20.0 source tree over the
summer. (Thanks Joe!)

In short, if you don't need the internationalization features and
you're not interested in participating in the upgrade path of XEmacs
until the new code stabilizes you should use 19.15.  If you like the
idea of running the latest code, but don't want to take the
performance hit of MULE, don't need to have non-Latin-1 language
support, and are willing to put up with the occasional incompatibility
caused by the change to the character type, then you should use
XEmacs-v20-latin-1.  If you wish the whole `v20 experience' as Kyle
Jones put it :-), then you should use XEmacs-v20-MULE.

Warning:  The MULE features are *highly* addictive (IMHO).
