Why are there different Ruby On Rails versions? -

-

disclaimer : totally new ruby on rails planning learning it.

this morning have been reading there 2 new ruby on rails releases (2.3.11 , 3.0.4).

i don't understand why people (the ror community) working (maintaining) different versions ? benefits developpers ?

active development not being done on 2.x branch. however, there lots , lots , lots of deployed 2.x applications in wild, , given yesterday's releases security-related patches, provided patch 2.x users.

upgrading rails application 2.x 3.x not easy or trivial, , it's unreasonable expect solution security hole, 2.3.11 release made instead.
