GNOME Session 3.7.4 (yes, 3.7.4 and not 3.7.5) is part of the upcoming GNOME 3.7.5 desktop environment, a development version towards the highly anticipated GNOME 3.8 release, which should see the light of day sometime at the end of March 2013. This development release of the GNOME Session (gnome-session) package comes with exactly 10 changes and updates over 20 languages. Apparently no bugs or serious issues have been fixed in this version. Also, we have no idea if the team will release a 3.7.5 version in time for the GNOME 3.7.5 announcement.
