* Update the glib to 2.34.3 and gtk20 to 2.24.17 and gtk30 to 3.6.4 which
  are the latest stable releases.
* Update vala to the newest stable release 0.18.1, also update a few ports
  in the gtk/gnome stack.
* The c++ bindings ports for glib, atk, gconf, etc, have now USE_GNOME toggles.
* Remove pkg-config run depends from glib20 and freetype2. This doesn't
  eliminate pkg-config run dependency completely, a second phase is needed
  and is planned.
* Support for .:run. and .:build. for USE_GNOME components was added.
  Currently only libxml2 and libxslt support this mechanism.
* Updates of the telepathy stack and empathy.
* Trim makefile headers, convert ports to new options, trim off library
  versions for some ports.
* Fix other ports so they build with the new glib version.

Thanks to miwi and crees for helping out with some exp-runs.

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.

Presenting GNOME 2.28.1 for FreeBSD.  The official release notes for this
release can be found at http://library.gnome.org/misc/release-notes/2.28/ .
Officially, this is mostly a polishing release in preparation for GNOME 3.0
due in about a year.

On the FreeBSD front, though, a lot went into this release.  Major thanks
goes to kwm and avl who did a lot of the porting work for this release.
In particular, kwm brought in Evolution MAPI support for better Microsoft
Exchange integration.  Avl made sure that the new gobject introspection
repository ports were nicely compartmentalized so that large dependencies
aren't brought in wholesale.

But, every GNOME team member (ahze, avl, bland, kwm, mezz, and myself)
contributed to this release.
