The first Rails 3.1 release candidate has been out for a couple weeks now, and the official release of 3.1.0 can't be far behind.

Upgrading To Rails 3.1

I upgraded a Rails 3.0 app to 3.1 this past weekend, and all in all, it was a pretty smooth process. Along the way, I was grateful to discover a few helpful posts from developers that had already made this journey. If you're getting ready to upgrade an existing app to Rails 3.1, or if you just want to get a feel for what to expect, I recommend checking out these write-ups.

If you're already up to speed on all the new features in Rails 3.1, then you're ready to give the upgrade a shot.

Still here? Well, I'm guessing that means you want to spend a bit more time wrapping your head around what's new in Rails 3.1, and then you'll be ready for the upgrade. Good news: you've got quite a few resources to lean on:

Party On, Dudes

If Rails 3.1 has piqued your curiosity, it's definitely worth a quick spike to try out an upgrade. Just create a branch and give it a shot. After all, you wrote all those tests for a reason, right? Take Rails 3.1 for a spin, and let your test suite tell you where things need to be patched up. What have you got to lose? Party on, Dudes!
