The Emacs 22.0.99 pretest is now available at
ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-22.0.99.tar.gz
ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-22.0.98-22.0.99.xdelta
Note that python-mode has been removed from this tarball. The legal
status of python.el is currently being discussed; see the thread on
emacs-pretest-bug. Maybe it will be resolved in time for Emacs 22.1,
maybe not. In the meantime, the version of python.el maintained by
Dave Love can be found at
http://www.emacswiki.org/cgi-bin/wiki/PythonMode
If no problems are found in this over the next few days, I think we
should release Emacs 22.1; but I guess that's up to RMS to decide.
