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
Supervisorthat 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.
