The second release of the GNOME 3.14 development cycle is here. See  for the new features that have been proposed for this cycle.
To compile GNOME 3.13.2, you can use the jhbuild  modulesets  (which use the exact tarball versions from the official release).
Note that as part of Wayland development, 3.13.2 temporarily depends on systemd. This is needed because Wayland support in GNOME depends on systemd, but before 3.14 is released Wayland support will be made optional.
This release is a snapshot of early development code. Although it is buildable and usable, it is primarily intended for testing and hacking purposes. GNOME uses odd minor version numbers to indicate development status.
