Hello Linux Geeksters. The Canonical developers are discussing whether Ubuntu 14.04 will use Gnome 3.10, or Gnome 3.8. Ubuntu 14.04 will be a LTS (long term supported) release, and so, the latest versions of the Gnome Desktop, Gnome 3.10 may produce instability.
The fact that the latest versions of Ubuntu did not use the latest GNOME versions has been an issue in the last years. Sebastien Bacher proposed this, in the mailing lists and also gave a few arguments supporting its proposal.
Using GNOME 3.8 on Ubuntu 14.04 LTS may offer stability, but will be unfair for the Gnome users, who want to have the latest GNOME apps on their system, or at least, not ones from two cycles behind.
A final decission will be probably made and released to the press after the official release of Ubuntu 13.10 Saucy Salamander.
As a reminder, Ubuntu 14.04 LTS will be released on the 17th of April, 2014 and will be a long term support version. The users will be able to test the first alpha version of Ubuntu 14.04 LTS on the 19th of December, 2013. More information can be found here.
