I have seen that there is no updates for Ruby 1.9.2. (Only for Ruby 1.9.3 & 2.0). My question is: what happened with 1.9.2?
I'm confused if 1.9.3 and 1.9.2 are different branches, or 1.9.3 is the sequel, and if my 1.9.2 app will works with 1.9.3 without problems.
If you're talking about updates to deal with CVE-2013-4073, then Ruby-lang.org says:
All users are recommended to upgrade to Ruby 2.0.0-p247, 1.9.3-p448 or 1.8.7-p374.
Presumably, anyone using MRI Ruby 1.9.2 is able to use MRI Ruby 1.9.3.
