Q:

Which Ruby on Rails version should I upgrade to?

I am using Ruby on Rails 3.2.9 and on the official blog it has been posted the following article: "[SEC] [ANN] Rails 3.2.13, 3.1.12, and 2.3.18 have been released!".
My question is: Which Ruby on Rails version should I upgrade to?

Note: I ask this because in the linked blog post (and in related linked pages) there is a bit of confusion. I would be grateful if someone would tell me a little more about the upgrades.

A:

I suggest to upgrade to the latest release of the branch you are currently using, i.e. from 3.2.9 to 3.2.13.
