In addition to the usual bugfixes and improvements (see /usr/share/doc/aegis-4.4/readme.txt.gz if you care), this is an important update because the previous aegis ebuild (for aegis 4.2) no longer works. It doesn't get on with gentoo's new gettext (gettext-0.11.1). This latest version of aegis has fixed that problem.
