Dear hAkkers,

We—the Akka committers—are pleased to be able to announce the availability
of Akka 2.3.3. This is the third maintenance release of the 2.3 branch. It
contains fixes for several issue*s and performance
optimizations*<https://github.com/akka/akka/issues?milestone=2&state=closed>
.

This version of Akka is released for both Scala 2.10.4 and 2.11.1. We are
coordinating this release with Scala 2.11.1 public announcement. For now
Akka 2.3.3 is being announced only on Akka mailing lists for your immediate
use. Please try it out and report your experience. Akka website will be
updated as Scala 2.11.1 is publicly announced.

Special actions should be taken if you were using Akka for Scala 2.11.0.
Here is the excerpt from the Scala mailing list:

Serialization was broken in Scala 2.11.0. The fix in 2.11.1 necessarily
breaks serialization compatibility between 2.11.0 and 2.11.1 (this is
separate from binary compatibility, which is maintained).

Users of distributed systems that rely on serialization to exchange objects
(such as akka) should upgrade to Scala 2.11.1 (and akka 2.3.3)
immediately. We also strongly recommend that libraries that themselves
declare classes with @SerialVersionUID annotations release a new version
and ask their Scala 2.11 users to upgrade.

We apologize for the breakage. We have included a new suite of tests that
will ensure stability of serialization for the remainder of the 2.11.x
series.
