Rails 3.1.2.rc2

Hi everyone,

Rails 3.1.2.rc2 has been released. Dont ask about rc1!

Please give it a try, but first read the important note below.

If there are no release blockers, then I will be releasing the final
version some time after 16:00 UTC on 17th November.

## IMPORTANT NOTE FOR RC TESTERS ##

Rails 3.1.2 will depend on sprockets 2.1. The current stable version of
sass-rails (3.1.4) depends on sprockets 2.0. To solve this problem, the
current sass-rails release candidate removes its explicit dependency on
sprockets, because sass-rails depends on actionpack which already
depends on sprockets, so the version should be specified there.

So to test this RC, you need to change your sass-rails dependency to:

    gem 'sass-rails', '~> 3.1.5.rc.2'

When Rails 3.1.2 final is released, the final version of sass-rails
3.1.5 will also be released, so people with '~> 3.1.4' in their Gemfile
will not have to do anything as Bundler will resolve the dependency
itself.
