 ## Unreleased
 
 ### Fixed
+-Incorrect coverage for methods returning IAsyncEnumerable in generic classes [#1383](https://github.com/coverlet-coverage/coverlet/issues/1383)
 -Allign published nuget package version to github release version [#1413](https://github.com/coverlet-coverage/coverlet/issues/1413)  
 -Sync nuget and github release versions [#1122](https://github.com/coverlet-coverage/coverlet/issues/1122)
