The
K Desktop Environment community came out earlier this year with their brand new
KDE 4.0 release that marked significant advancements to this open-source desktop environment compared to its KDE 3.5.x code-base. Meanwhile, the
GNOME community has been living in a 2.0 cycle for quite some time with no signs of a major overhaul, but their six-month release cycles just continue to deliver new refinements and minor improvements. The
plans for GNOME 3.0 just put this release out when there is significant API/ABI breakage to GNOME 2.0 / GTK+ or a major rewrite. Well, in addition to announcing Stormy Peters joining GNOME, at
GUADEC 2008 they have just announced plans for GNOME 3.0!
The details are still emerging from this GNOME conference taking placed in Istanbul, Turkey. All the information that has reached the Internet so far are several GNOME developers briefly mentioning it on their blogs (aggregated through
Planet GNOME). The only real information that has hit the blogs so far is that
GNOME 2.30 = GNOME 3.0. This was mentioned on
Vincent Untz's blog with a photograph. As of yet, no GNOME 3.0 information has appeared on any of the GNOME mailing lists.

Permitting that the GNOME development community will be continuing with their six-month release cycles and they plan on having GNOME 2.26 and GNOME 2.28 stable releases before GNOME 2.30/3.0, this would place their effective release date for GNOME 3.0 in early 2010. In fact, it would be right before the release of Ubuntu 10.4 LTS.
Meanwhile, the next GNOME release is
GNOME 2.24 and its release is targeted for September. When we have any other information on
GNOME 3.0 we will be sure to pass it along. Share your hopes and expectations for GNOME 3.0 in the
Phoronix Forums.
UPDATE: With GNOME 3.0 will come GTK+ 3.0. Lucas Rocha just
blogged about GTK+ 3.0 / GNOME 3.0 and that the transition process from GNOME 2 to GNOME 3 is expected to be smooth.
