Rails 2.1 is now available for general consumption with all the features and fixes we’ve been putting in over the last six months since 2.0. This has been a huge effort by a very wide range of contributors helping to make it happen.

Over the past six months, we’ve had 1,400 contributors creating patches and vetting them. This has resulted in 1,600+ patches. A truly staggering number. And lots of that has made it into this release.

New features
The new major features are:

• Time zones (by Geoff Buesing): Tutorial | Introdction | Railscast
• Dirty tracking: Introduction (partial updates) | Railscast
• Gem Dependencies: Introduction | Railscast
• Named scope (by Nick Kallen): Introduction | Railscast
• UTC-based migrations: Introduction | Railscast
• Better caching: Introduction

Thanks to Ryan Daigle for the feature introductions and Ryan Bates for the Railscasts. It makes writing the release notes so much easier :).

As always, you can install with:

gem install rails

…or you can use the Git tag for 2.1.0.

Enjoy!
