### Bug fixes

* Fix auto-correction of array and hash literals in `Lint/LiteralInInterpolation`. ([@lumeet][])
* [#2815](https://github.com/rubocop/rubocop/pull/2815): Fix missing assets for html formatter. ([@prsimp][])
* `Style/RedundantParentheses` catches offenses involving the 2nd argument to a method call without parentheses, if the 2nd argument is a hash. ([@alexdowad][])
* `Style/RedundantParentheses` catches offenses inside an array literal. ([@alexdowad][])
* `Style/RedundantParentheses` doesn't flag `method (:arg) {}`, since removing the parentheses would change the meaning of the expression. ([@alexdowad][])
* `Performance/Detect` doesn't flag code where `first` or `last` takes an argument, as it cannot be transformed to equivalent code using `detect`. ([@alexdowad][])
* `Style/SpaceAroundOperators` ignores aref assignments. ([@alexdowad][])
* `Style/RescueModifier` indents code correctly when auto-correcting. ([@alexdowad][])
* `Style/RedundantMerge` indents code correctly when auto-correcting, even if the corrected hash had multiple keys, and even if the corrected code was indented to start with. ([@alexdowad][])
* [#2831](https://github.com/rubocop/rubocop/issues/2831): `Performance/RedundantMerge` doesn't break code by autocorrecting a `#merge!` call which occurs at tail position in a block. ([@alexdowad][])

### Changes

* Handle auto-correction of nested interpolations in `Lint/LiteralInInterpolation`. ([@lumeet][])
* RuboCop results cache uses different directory names when there are many (or long) CLI options, to avoid a very long path which could cause failures on some filesystems. ([@alexdowad][])
