## 3.0.0 / not yet released / branch "master"
* ...
* Remove ActionView template handler [Dylan Thacker-Smith, dylanahsmith]
* Freeze lots of string literals for new Ruby 2.1 optimization, see #297 [Florian Weingarten, fw42]
* Allow newlines in tags and variables, see #324 [Dylan Thacker-Smith, dylanahsmith]
* Tag#parse is called after initialize, which now takes options instead of tokens as the 3rd argument. See #321 [Dylan Thacker-Smith, dylanahsmith]
