<commit_before>### v0.3.0.pre

**NOTE:** v0.3.0.pre is currently [failing its Rubinius build](https://travis-ci.org/normalocity/how_slow).
I'm looking into it.

#### Breaking changes (versus v0.2.x):

* Refactored the `HowSlow::config` options - you will **definitely**
  [want to take a look at the new structure], 
  as they are very likely to break your previous use of `HowSlow 0.2.0`
* Possible breakage of Rails 4 support. More specifically I changed the
  `how_slow.gemspec` file to **exclude** Rails 4 support (for now)
* No longer support Rails 3.0 (bumped minimum version to Rails 3.1)
* Changed `HowSlow` from a `Rails::Railtie` to a `Rails::Engine` in order
  to make the mailer views easily available and override-able in the
  app that is using `HowSlow`

#### Other code changes

* Added [email report support!](https://github.com/normalocity/how_slow/issues/12)<commit_msg>Updated note about Rubinius build. Fixed a broken link.<commit_after>### v0.3.0.pre
