Akka 2.5.29 Released

Dear hakkers,

We are pleased to announce the 2.5.29 patch release of Akka 2.5. The release contains backports of a few important fixes.

Notable changes:

  • Improve performance of composite ByteString.toArray. #28137
  • Fix memory leak of restarting Artery outbound stream. #28390
  • Backport some of the SystemMaterializer API. #28494
  • Timestamp in EventEnvelope of Persistence Query. Persistence plugins should start using it. #28331

Version 2.5.28 was never announced because it included a major regression due to the the change of the EventEnvelope. Thanks to @nvollmar for finding and fixing. #28532
