Dear hakkers,

We are pleased to announce a new patch release of Akka 2.5. Some notable improvements and bug fixes in 2.5.20 are:

  • Discovery and DNS APIs are now stable
  • New stream functionality: SourceWithContext and FlowWithContext allows for keeping a context object “on the side” while processing an element. #25951
  • Improvements of default shard rebalancing algorithm, #26012
  • The serializer manifest is now logged when a serializer is missing to help figuring out such errors #26217
  • The cluster join compatibility check now supports rolling upgrades #26194
  • An optimization to AtLeastOnceDelivery - only tick when there are unconfirmed deliveries #26216
  • Terminate StreamRef on node failure #25960
  • SelfUniqueAddress instead of Cluster parameter in some Distributed Data types (old signatures have been deprecated) #25746

A total of 72 issues were closed since 2.5.19. The complete list can be found on the 2.5.20 milestone on github.
