Rails 2 support after Rails 3 has been released

Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been re开发者_JAVA百科leased?

I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

You'll be fine with Rails 2.3.x for awhile now. Rails 3 is still in beta and the 2.3 branch will receive security updates for awhile (after Rails 3 is released) before it's abandoned by the core team.

Rails 2 features such as ActiveRecord finder syntax, routing syntax etc. that are deprecated in Rails 3 are set to be removed in Rails 3.1 I believe.

---

Now that Rails 4 is about to hit, official support for Rails 2 will definitely end. There is a commercial service (railslts.com) that will continue to provide security updates for Rails 2.3 applications.
