Akka 2.6.2 Released

Important Note A show stopping bug in Akka Persistence was introduced in this release, but has since been fixed, please skip 2.6.2 and move directly to 2.6.3

Dear hakkers,

We are pleased to announce a new patch release of Akka 2.6. Notable changes relative to 2.6.1 include:

  • New external shard allocation strategy. The canonical use case is to match up Kafka Partition consumption with shard locations to avoid network hops. #28175
  • Improve performance of composite ByteString.toArray. #28137
  • Streams filter changed behavior to eagerly filter out elements without demand from downstream. #28467
  • Timestamp in EventEnvelope of Persistence Query. Persistence plugins should start using it. #28331
  • Support JDK Flight Recorder for Artery events. #26282
  • Fix memory leak of restarting Artery outbound stream. #28390
  • Fix wrong logging “Marking node as REACHABLE” #28393
  • Fix ReceiveTimeout not triggered after actor restart. #28266
  • Fix EventSourcedBehavior not failing with DeathPactException for unhandled Terminated signals #28297
  • LevelDB live persistence query stream should no complete when no events. #28428
  • API for defining dispatcher of pool routees. Thanks to @CodeLionX #28370
  • Publish operations (events) from InmemJournal. #28332
  • Update to ScalaTest 3.1.0, which means that users of ScalaTestWithActorTestKit in akka-actor-testkit need to migrate, or create their own copy of the old ScalaTestWithActorTestKit. 28289.
