rubocop/rubocop v0.20.0

RuboCop 0.20.0

on GitHub

There aren't many exciting new features this time around - our focus in 0.20 has been fixing most of the problems we introduced in 0.19. Apart from that we've added a few new cops and implemented auto-correct for a bunch of the existing cops.

You'll also notice that the messages produced by most formatters a bit more colorful (and hopefully more readable as well).

You should also note that AllCops/Includes and AllCops/Excludes have been renamed, so you'll have to update your config files accordingly.

Below is the list of all the gory details. Enjoy!
