v0.22.0

Enhancements

• On Ruby 3.2+, you can now use the new Coverage library feature for eval - See #1037. Thanks @mame!

Bugfixes

• Fix for making the test suite pass against the upcoming Ruby 3.2 - See #1035. Thanks @mame

v0.21.2

Bugfixes

• maximum_coverage_drop won't fail any more if .last_run.json is still in the old format. Thanks @petertellgren
• maximum_coverage_drop won't fail if an expectation is specified for a previous unrecorded criterion, it will just pass (there's nothing, so nothing to drop)
• fixed bug in maximum_coverage_drop calculation that could falsely report it had dropped for minimal differences

v0.21.1

Bugfixes

• minimum_coverage_by_file works again as expected (errored out before 😱)

v0.21.0

The "Collate++" release making it more viable for big CI setups by limiting memory consumption. Also includes some nice new additions for branch coverage settings.

Enhancements

• Performance of SimpleCov.collate improved - it should both run faster and consume much less memory esp. when run with many files (memory consumption should not increase with number of files any more)
• Can now define the minimum_coverage_by_file, maximum_coverage_drop and refuse_coverage_drop by branch as well as line coverage. Thanks to @jemmaissroff
• Can set primary coverage to something other than line by setting primary_coverage :branch in SimpleCov Configuration. Thanks to @jemmaissroff

Misc

• reduce gem size by splitting Changelog into Changelog.md and a pre 0.18 Changelog.old.md, the latter of which is not included in the gem
• The interface of ResultMeger.merge_and_store is changed to support the collate performance improvements mentioned above. It's not considered an official API, hence this is not in the breaking section. For people using it to merge results from different machines, it's recommended to migrate to collate.

v0.20.0

The "JSON formatter" release. Starting now a JSON formatter is included by default in the release. This is mostly done for Code Climate reasons, you can find more details in this issue.
Shipping with so much by default is sub-optimal, we know. It's the long term plan to also provide simplecov-core without the HTML or JSON formatters for those who don't need them/for other formatters to rely on.

Enhancements

• simplecov_json_formatter included by default (docs), this should enable the Code Climate test reporter to work again once it's updated
• invalidate internal cache after switching SimpleCov.root, should help with some bugs

v0.19.1

Bugfixes

• No more warnings triggered by enable_for_subprocesses. Thanks to @mame
• Avoid trying to patch Process.fork when it isn't available. Thanks to @MSP-Greg
