I have heard, but can't find an official reference to it now, that Rails 2.3 will stop receiving security updates once Rails 4 is released. (I suspect that patches will still become available for serious issues even once official support is dropped.)

Rails Core will not support 2.3.X, in any fashion, after 4.X is released. It is not relevant to their interests. It is very relevant to my interests, so watch for a coming announcement on my blog, or (an alternative) switch to Gthub's fork of 2.3.X.

Right - that's what I've heard, but that email doesn't explicitly say that.

Right, so you have your migration to Rails 3 ready to go as soon as Rails 4 ships. When Rails N has shipped, consider Rails N-1 to have become the "stable" release and Rails N-2 to be deprecated.
