=================

## Enhancements

* Added `SimpleCov.minimum_coverage_by_file` for per-file coverage thresholds. \ 
See [#392](https://github.com/colszowka/simplecov/pull/392) (thanks @ptashman)
* Added `track_files` configuration option to specify a glob to always include \ 
in coverage results, whether or not those files are required. See \ 
[#422](https://github.com/colszowka/simplecov/pull/422) (thanks @hugopeixoto)
* Speed up `root_filter` by an order of magnitude. See \ 
[#396](https://github.com/colszowka/simplecov/pull/396) (thanks @raszi)

## Bugfixes

* Fix warning about global variable `$ERROR_INFO`. See \ 
[#400](https://github.com/colszowka/simplecov/pull/400) (thanks @amatsuda)
* Actually recurse upward looking for `.simplecov`, as claimed by the \ 
documentation, rather than only the working directory. See \ 
[#423](https://github.com/colszowka/simplecov/pull/423) (thanks @alexdowad)
