Nothing particularly exciting this time around. The new release comes
with lots of bug fixes, more auto-corrections and several new cops.

Note that the `Style/Encoding` cop is now disabled by default. See
[#1304](https://github.com/rubocop/rubocop/issues/1304) for the
rationale behind this change.

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

### New features

* New cop `SpaceInsideRangeLiteral` checks for spaces around `..` and `...` in range literals. ([@bbatsov][])
* New cop `InfiniteLoop` checks for places where `Kernel#loop` should have been used. ([@bbatsov][])
* New cop `SymbolProc` checks for places where a symbol can be used as proc instead of a block. ([@bbatsov][])
* `UselessAssignment` cop now suggests a variable name for possible typos if there's a variable-ish identifier similar to the unused variable name in the same scope. ([@yujinakayama][])
* `PredicateName` cop now has separate configurations for prefixes that denote predicate method names and predicate prefixes that should be removed. ([@bbatsov][])

* [#1304](https://github.com/rubocop/rubocop/issues/1304): `Style/Encoding` is no longer a no-op on Ruby 2.x. It's also disabled by default, as projects not supporting 1.9 don't need to run it. ([@bbatsov][])
