The much anticipated Rails 2.2 release is finalized with a host of new features. One of the features we are most excited about are the new multi-threaded capabilities for Rails. This will improve application response time in general, and allow us to get more use out of each server. I think memoization can be useful as well, it will be interesting to see how much it helps. As usual, Peter Cooper at Ruby Inside has put together an all-encompassing post with all the info you might need. And as a side note, this release also includes a little patch submitted by our team.

Thanks and congratulations to the core team for another solid release.
