You thought we were never going to get to this day, didn’t you? Ye of little faith. Because here is the first real, public release of Rails 3.0 in the form of a beta package that we’ve toiled long and hard over.
It’s surely not perfect yet, but we were out of blockers on the list, so here we go. Please give it a run around the block, try to update some old applications, try to start some new ones, and report back all the issues you find.
I’m really proud of this moment, actually. We’ve had more than 250 people help with the release and we’ve been through almost 4,000 commits since 2.3 to get here. Yet still the new version feels lighter, more agile, and easier to understand. It’s a great day to be a Rails developer.
There’s plenty to get excited about here. A few of the headliner features are:
- Brand new router with an emphasis on RESTful declarations
- New Action Mailer API modelled after Action Controller (now without the agonizing pain of sending multipart messages!)
- New Active Record chainable query language built on top of relational algebra
- Explicit dependency management with Bundler
But please take a look at the full release notes and enjoy the latest!
