Akka 2.4.1 Released!
November 27 2015
Johan Andrén

Dear hAkkers,

We—the Akka committers—are pleased to be able to announce the availability of Akka 2.4.1.

This release contains a few important fixes and improvements:

  • Shard region now kills shards more consistently on HandOff
  • An empty shard region now shuts down correctly on graceful shutdown
  • Using the distributed data mode the sharding coordinator updates correctly after leader downing
  • Possibility to provide a custom supervision strategy for the BackOffSupervisor
  • Problem with split brain on cluster startup under some circumstances solved
  • A new Supervisor that supports exponential restart back-off semantics for actors regardless of their lifecycle model (the BackoffSupervisor overloads the meaning of self-termination)

The complete list of closed tickets can be found in the 2.4.1 github issues milestone.

Akka 2.4.1 is released for Scala 2.11, 2.12.0-M3 and Java 8.

Additional Release Details

The artifacts comprising this release have been published to https://oss.sonatype.org/content/repositories/releases/ and also to Maven Central. In addition, we adopted the sbt standard of encoding the Scala binary version in the artifact name, i.e. the core actor package’s artifactId is “akka-actor_2.11”.
