Akka 2.3.11 Released!
May 12 2015

Dear hAkkers,

We—the Akka committers—are pleased to be able to announce the availability of Akka 2.3.11. This is the eleventh maintenance release of the 2.3 branch. This release contains a few important fixes:

  • a fix for BatchingExecutor (#16327; symptom is a requirement failure when using blocking{} in Future callbacks)
  • a fix for a performance regression caused by a previous bugfix in IO (#17391)
  • a revert of a performance optimization in 2.3.7 that caused actor starvation when multiple dispatchers were involved (#17341; critical)

This release also adds an additional configuration parameter for ForkJoinPool as well as a fix for a wrong setting path in Pinned Dispatcher configuration.

Akka 2.3.11 is released for Scala 2.10.4 and 2.11.5. 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 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_2.10” or “akka-actor_2.11”, respectively.

The complete list of closed tickets can be found in the 2.3.11 github issues milestone.
