Upgrade from 2.6.10
I am planing to upgrade my Redmine from 2.6.10 to 3.X [3.0.X, 3.1.X, 3.2.X, 3.3.X].
I am using mysql version: [Ver 14.14 Distrib 5.1.73], I don't intend to upgrade mysql for now.
Please suggest what version I should upgrade to on basis of support duration. I am unable to find the maintenance period for 3.1.x , 3.2.x and 3.3.x versions.
The only reason I see not to get the latest would be some issues with plugin compatibility (you might want to test beforehand!).
That or other compatibility issues, like a shared ruby version with other services (which can easily be bypassed using RVM).
