The GNOME 3.23.3 unstable release was in fact planned to be seeded to public testers tomorrow, December 14, 2016, but it looks like it arrived earlier for early adopters and those who want to help the GNOME development team discover the remaining blockers before GNOME 3.24 enters Beta, which should happen in mid-February 2017. GNOME 3.23.3 is also the last development snapshot planned for 2016 as the team will now take a well-deserved break to enjoy the winter holidays with their families and friends. This version ships with updated version of most of the core components and apps distributed as part of the GNOME Stack.
