Which version to use?
I note that currently, if I want to download vanilla forum it suggests Version 18.104.22.168
But commercial hosted plan running on Version 2.2.5.
I also can see in git repository 2.0 and 2.1 branches plus 22.214.171.124 and 2.1b2 tags.
Which one is most stable?
AND if I am developer, and ready to go deep into bugs fixing/debuging/testing/contributing/ which version is latest?
