The new gem version dependency system from Rails 1.1.1 needed a few tweaks to work properly and to stop throwing meaningless warnings. This tiny release makes up for that. To install:
gem install rails
rake rails:update:configs(to get the latest config/boot.rb)
This release also signals our new commitment to do more tiny releases from the stable branch, which only gets bug fixes. So it will not be uncommon to see bi-weekly tiny releases in the 1.1.x series while we continue to add features to the forthcoming 1.2.0.
