Akka 2.3.8 Released!

Dear hAkkers,

We—the Akka committers—are pleased to be able to announce the availability of Akka 2.3.8. This is the eighth maintenance release of the 2.3 branch. This release contains a few improvements and one new feature:

  • fix a bug in Clustering that could lead to Terminated being fired for remote actors without removing that remote node from the cluster
  • improve validation of actor names to work even for extremely long ones (several kilobytes)
  • fix a wrong link in the Remoting documentation, thanks hepin1989!
  • allow suppression of dead letter warnings for certain message types (mostly internal feature, see here for details)

Akka 2.3.8 is released for Scala 2.10.4 and 2.11.4. This release is backwards binary compatible with all previous 2.3.x versions which means that the new JARs are a drop-in replacement for the old one (but not the other way around) as long as your build does not enable the inliner (Scala-only restriction). Always make sure to use at least the latest version required by any of your project’s dependencies.

Migrating from Older Relases

When migrating an existing project from Akka 2.2.x please have a look at the migration guide.

Additional Release Details

The artifacts comprising this release have been published to 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_2.10” or “akka-actor_2.11”, respectively.

The complete list of closed tickets can be found in the 2.3.8 github issues milestone.
