Akka 2.6.0-M2 released

Dear hakkers,

The second development milestone for Akka 2.6 is out.

It would be excellent if you can try the milestones out and give us feedback. Akka 2.6 is binary backwards compatible with 2.5 with the ordinary exceptions listed in the documentation. Some configuration changes may be needed, please read the migration guide as a first step.

Some notable changes in 2.6.0-M2:

  • Jackson serializer as replacement for Java serialization. It is not feature complete but good enough for first trial, see documentation #26870
  • Use standard fork join pool in the JDK instead of old embedded version #26180
  • Release for Scala 2.13.0-RC (and 2.12) #26964
  • Enable passivation of Cluster Sharding entities by default #25782
  • New Scheduler API in Akka Typed (only ActorSystem.scheduler) 26971
  • Router pool in Akka Typed changed to take behavior factory #26982
  • Expose event stream as an ActorRef in Akka Typed thanks to @vaslabs #21525
  • Add missing EventSourcedEntity.withEnforcedReplies in Akka Typed #26692
  • Promote some ApiMayChange features #26532
  • Some new deprecations, see migration guide
  • Fixes that were also backported to 2.5.23

A total of 54 issues were closed since 2.6.0-M1. The complete list can be found on the 2.6.0-M2 milestone on github.
