Koop Mast 48e62d9a37 Presenting GNOME 2.30.1 for FreeBSD. The offical release notes for this 
release can be found at http://library.gnome.org/misc/release-notes/2.30/ .

This release brings initial PackageKit support, Upower (replaces power
management part of hal), cuse4bsd integration with HAL and cheese, and a
faster Evolution.

Sadly GNOME 2.30.x will be the last release with FreeBSD 6.X support. This
will also be the last of the 2.x releases. The next release will be the
highly-anticipated GNOME 3.0 which will bring with it a new UI experience.

Currently, there are a few bugs with GNOME 2.30 that may be of note for our
users. Be sure to consult the UPGRADING note or the 2.30 upgrade FAQ at
http://www.freebsd.org/gnome/docs/faq230.html for specific upgrading
instructions, and the up-to-date list of known issues.

This release features commits by avl, ahze, bland, marcus, mezz, and myself.

The FreeBSD GNOME Team would like to thank Anders F Bjorklund for doing the
initual packagekit porting.

And the following contributors & testers for there help with this release:
Eric L. Chen
Vladimir Grebenschikov
