([changes](https://github.com/colszowka/simplecov/compare/v0.14.0...v0.14.1))
========

## Bugfixes

Float errors. See [#564](https://github.com/colszowka/simplecov/pull/564) \

([changes](https://github.com/colszowka/simplecov/compare/v0.13.0...v0.14.0))
==========

## Enhancements

* Officially support JRuby 9.1+ going forward (should also work with previous \ 
releases). See [#547](https://github.com/colszowka/simplecov/pull/547) (ping \ 
@PragTob when encountering issues)
* Add Channel group to Rails profile, when `ActionCable` is loaded. See \ 
[#492](https://github.com/colszowka/simplecov/pull/492) (thanks @BenMorganIO)
* Stop `extend`ing instances of `Array` and `Hash` during merging results \ 
avoiding problems frozen results while manually merging results. See \ 
[#558](https://github.com/colszowka/simplecov/pull/558) (thanks @aroben)

## Bugfixes

* Fix parallel_tests when a thread ends up running no tests. See \ 
[#533](https://github.com/colszowka/simplecov/pull/533) (thanks @cshaffer)
* Skip the `:nocov:` comments along with the code that they skip. See \ 
[#551](https://github.com/colszowka/simplecov/pull/551) (thanks @ebiven)
* Fix crash when Home environment variable is unset. See \ 
[#482](https://github.com/colszowka/simplecov/pull/482) (thanks @waldyr)
* Make track_files work again when explicitly setting it to nil. See \ 
[#463](https://github.com/colszowka/simplecov/pull/463) (thanks @craiglittle)
* Do not overwrite .last_run.json file when refuse_coverage_drop option is \ 
enabled and the coverage has dropped (lead to you being able to just rerun tests \ 
and everything was _fine_). See \ 
[#553](https://github.com/colszowka/simplecov/pull/553) (thanks @Miloshes)

See [#520](https://github.com/colszowka/simplecov/pull/520) (thanks @alyssais)
* Only read in source code files that are actually used (faster when files are \ 
ignored etc.). See [#540](https://github.com/colszowka/simplecov/pull/540) \ 
(tahks @yui-knk)

[dc7417d50](https://github.com/colszowka/simplecov/commit/dc7417d5049b1809cea214314c15dd93a5dd964f) \ 
(thanks @amatsuda)
