*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
   <https://github.com/akka/akka/issues/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 <https://github.com/akka/akka/issues/17391>)
   - a revert of a performance optimization in 2.3.9 that caused actor
   starvation when multiple dispatchers were involved (#17341
   <https://github.com/akka/akka/issues/17341>; critical)

This release also adds an additional configuration parameter
<https://github.com/akka/akka/issues/17274> for ForkJoinPool as well as a
fix for a wrong setting path <https://github.com/akka/akka/issues/17316> 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
<http://doc.akka.io/docs/akka/2.3.11/project/migration-guide-2.2.x-2.3.x.html>
.
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 <https://github.com/akka/akka/issues?q=milestone%3A2.3.11>.
