Rails 0.14.4 RC5 is out. You can get it now with Edge Rails or soon with RubyGems.

If you’re interested in staying really on top of this, you can set up an account at RubyForge.org and click the ‘monitor’ icon in the project summary page. You’ll get an email when new versions are available.

UPDATE: As you probably know by now, you can update with

  gem install rails --include-dependencies

If moving up from another 0.14.x, you should be done. Do not call ‘rails’ over your application to upgrade. One nice feature with the 0.14 series is that a lot of the common code (e.g. everything under /script) is moved out of your application’s directory. There will be less updating to do to your application.

If you’re upgrading from an earlier version, here’s the guidebook.
