View Poll Results: What Release Model Would You Like Best?
Current One - 3 Releases in 2 Years, Some Upgrades via Build Service 11 Rolling Release - "stable", "current" and "factory" well tested upgrade for stable 13 6 Monthly Release following KDE & GNOME 2 Annual Release with more time for Development & Testing 13 Other (please explain your preference) 3
The votes for annual took off, after posting in the "install" section of forum. A lot of ppl seem to be upgrading from 11.0, without a clear reason why, just to have the latest. Then running into forseeable troubles and known issues.
There's some comments about the "stress" factor of upgrading the release. Rolling release appeals, precisiely because many small steps are less worrying than a huge automatic one, that updates the whole system.
So the proposed schedule would appear to be popular with most of the user base, who've responded.
