Ruby on Rails 2.2 is Out, Improved Web Framework for Everybody

No matter how you call this open source web application framework, be it by its official Ruby on Rails name, be it RoR or simply Rails, the good news is that the Rails Core Team has as of recently released the final Ruby on Rails v. 2.2 to the general public.

“Rails 2.2 is finally done after we cleared the last issues from the release candidate program. This release contains a long list of fixes, improvements, and additions that’ll make everything Rails smoother and better, but we also have a number of star player features to parade this time,” says David Heinemeier Hansson, creator of Ruby on Rails .


The features in Ruby on Rails 2.2 that will certainly catch your eye are as follows: default internationalization, improved etag and better support for last-modified, connection pool, thread safety, full compatibility with RoR 1.9 and JRuby as well as better application programming interface (API for short).

Let’s take a brief but comprehensive look at all these features:
- Default internationalization means that Ruby on Rails 2.2 has “a full-on internationalization framework and that it’s pre-wired from start.”
- Improved etag and better support for last-modified refer to the HTTP validators.
- Connection pool and thread safety refer to the fact that Rail elements are thread safe and the fact that a suitable connection pool has been added for Active Record.
- Better API means that improvements have been made to API docs and several guides sections have been added.
- Full compatibility with RoR 1.9 and JRuby – this one is self-explanatory.

Here is what Nathan Torkington, O'Reilly Program Chair with OSCON, had to say a while back about the software: “Ruby on Rails is astounding. Using it is like watching a kung-fu movie, where a dozen bad-ass frameworks prepare to beat up the little newcomer only to be handed their asses in a variety of imaginative ways.”
