Rails 3 has officially dropped. I've been following the progress since it branched and I think the core team (and all the contributors) have done a great job. Not only does rails 3 have some great new features, but the refactoring under the hood means that plugin development will continue to grow. Bundler has already made my day to day rails development much easier and the UJS helpers are a great way to approach javascript support. Having the libraries use delegation is a simple and elegant solution to a complex problem. All in all, very well done. It might have taken a little longer than expected, but the upgrade process is fairly easy, and the learning curve isn't bad.

Again, from us here at agile productions,

Congratulations and Thank You to all involved.
