Bug fix release
The rails-3.2.0.rc2 release broke
stub_model in rspec-rails-2.0.0 > 2.8.0.
The rspec-rails-2.8.1 release fixes this issue, but it means that when you
upgrade to rails-3.2.0.rc2 or greater, you’ll have to upgrade to
rspec-rails-2.8.1 or greater.
Because rspec-rails-2.8.1 supports all versions of rails since 3.0, I recommend that you upgrade to rspec-rails-2.8.1 first, and then upgrade to rails-3.2.0.rc2 (or 3.2.0 once it’s out).
