Scala 2.12.13 includes general bug fixes and performance improvements to the collection libraries and the compiler backported from Scala 2.13.x. Scala 2.13.4 restores default global `ExecutionContext` to 2.12 behavior (to fix a perf regression in some use cases) and improves pattern matching (especially exhaustiveness checking). Most of the changes are related to the latter as I have enabled the newly introduced `-Xlint:strict-unsealed-patmat`. More details on the code changes: * Don't swallow exception in `ReassignPartitionsCommand.topicDescriptionFutureToState`. * `RequestChannel.Response` should be `sealed`. * Introduce sealed ClientQuotaManager.BaseUserEntity to avoid false positive exhaustiveness warning. * Handle a number of cases where pattern matches were not exhaustive: either by marking them with @unchecked or by adding a catch-all clause. * Workaround scalac bug related to exhaustiveness warnings in ZooKeeperClient * Remove warning suppression annotations related to the optimizer that are no longer needed in ConsumerGroupCommand and AclAuthorizer. * Use `forKeyValue` in `AclAuthorizer.acls` as the scala bug preventing us from using it seems to be fixed.
