⚠️ This version contains breaking changes ⚠️

What's Changed

• New option labels-to-remove-when-stale enables users to specify list of comma delimited labels that will be removed when the issue or PR becomes stale by @​panticmilos https://github.com/actions/stale/issues/770
• Skip deleting the branch in the upstream of a forked repo by @​dsame https://github.com/actions/stale/pull/913
• abort the build on the error by @​dsame in https://github.com/actions/stale/pull/935

Breaking Changes

• In this release we prevent scenarios when the build is not interrupted on some exceptions, which led to successful builds when they are supposed to fail
