Ruby on Rails updated to version 1.2.3

We’ve updated the default version of Ruby on Rails on our servers to version 1.2.3.

If you use Rails and you haven’t explicitly chosen your own version, it’s a good idea to check your applications and make sure there are no problems. (But if you’re concerned about compatibility, it’s probably best to freeze Rails anyway so that server upgrades like this won’t, and can’t, affect your application.)
