## Bugfixes

0.9.2, 2015-02-18 \ 
([changes](https://github.com/colszowka/simplecov/compare/v0.9.1...v0.9.2))
====================

This is a minor bugfix release for simplecov-html, released as `0.9.0`. Due to \ 
the tight version constraint in the gemspec
a new release of simplecov had to be shipped to allow using simplecov-html \ 
`~> 0.9.0`.
