The major changes are vast improvements for the mercurial (hg) backend
(which was done almost entirely by Seth); improved documentation (mostly
done by Simon and again Seth); quilt support (as an addon and stand
alone, see the manual for details); a number of new hooks and a fair
share of bugfixes.
