The Gnome development team has announced the release of Gnome 3.7.4. This is adevelopment release, and stricrtly recommended for those who are willing to test the upcoming Gnome 3.8 features. That said, not everything has been updated in this relase. Some of the core applications such as Nautilus, Tracker and Gnome Boxes have not been updated for this release because of some build bugs and other problems.
According to the announcement:
This got delayed by a few days as we were waiting for tarballs but here is GNOME 3.7.4, it has many new things, if you didn't yet, you should go and read Planet GNOME, recent posts by Allan Day, Matthias Clasen, and Cosimo Cecchi all cover improvements that made it in this release.
Still this is a development release and we had to do it while missing some important tarballs, most importantly we had to do with an older tracker tarball, and that makes building gnome-boxes, gnome-documents, and nautilus impossible :/
You can download the sources and compile them in your machine using jhbuild. Binaries are not yet available, but will hit gnome testing repos and PPAs soon.
