This is the eleventh major release in the Cats Effect 3.x lineage. It is fully binary compatible with every 3.x release, and fully source-compatible with every 3.2.x release.
This release fixes a regression in the work-stealing fiber scheduler. In addition, it reverts a change to the Async#fromPromise and IO.fromPromise signatures which was source-incompatible in numerous common scenarios due to limitations in Scala's type inference.
