rspec-core-2.5.1
This release breaks compatibility with rspec/autotest/bundler integration, but does so in order to greatly simplify it.
With the release of rspec-core-2.5.1, if you want the generated autotest command to include bundle exec, require Autotest’s bundler plugin in a .autotest file in the project’s root directory or in your home directory:
require "autotest/bundler"
Now you can just type ‘autotest’ on the commmand line and it will work as you expect.
If you don’t want ‘bundle exec’, there is nothing you have to do.
