The GNOME team has released RC1 of GNOME 2.16. "We are pleased to announce the release of GNOME 2.16.0 Release Candidate 1 (2.15.92). This is one of the last releases in the 2.15 development series and represents a release that is now API/ABI, feature, string and UI frozen. Hard code freeze is quickly approaching : this means that we're pretty close to the final 2.16.0 release. The GNOME contributors are now busy fixing the most important bugs that are still out there, localizing the whole desktop or updating our documentation." You can use jhbuild or GARNOME to build it.
