Rails 1.1 introduces greater than 500 enhancements and fixes. Here’s one of the more obscure ones that you may not hear about otherwise. I was able to slip a trivial (one line) patch in just under the wire for Rails 1.1 before it went out yesterday. Now you can do this:
  rake db:fixtures:load FIXTURES=people

or multiple:

  rake db:fixtures:load FIXTURES=people,surveys

Not a big deal for the average Rails developer, but when you’ve got 150+ models and 6.5MB of fixtures like we do it makes a big difference.
