0.2.2 (2017-05-21) New features: * [FEATURE #341](https://github.com/rust-lang/regex/issues/341): Support nested character classes and intersection operation. For example, `[\p{Greek}&&\pL]` matches greek letters and `[[0-9]&&[^4]]` matches every decimal digit except `4`. (Much thanks to @robinst, who contributed this awesome feature.)
