This release represents a formal commitment to underscores (dots are no longer supported), which allowed us to reduce the code base by nearly 10%. http://rubyforge.org/frs/shownotes.php?release_id=6377 http://rspec.rubyforge.org/ To be clear, if you have dots in your examples, they may break. The only exception to the rule is after "once" or "twice" when setting mock expectations: http://rspec.rubyforge.org/documentation/mocks.html Additionally, there are several other improvements to the mock API, as well as some bug fixes. Enjoy! David
