Typesafe Stack 1.1

We are proud to announce the release of Typesafe Stack 1.1.

The Typesafe Stack is a distribution of the Scala language and core tools, along with Akka event-driven middleware. Commercial support and maintenance for the Typesafe Stack is available via the optional Typesafe Subscription.

Typesafe Stack 1.1 includes Scala 2.9.1 and Akka 1.2.

Scala 2.9.1 is a maintenance release with many bug fixes and performance improvements, in particular to the interpreter. The full release notes for Scala 2.9.1 are available at the Scala language community site.

Akka 1.2 is also partly maintenance release paving the way for the upcoming Akka 2.0 release, but adds some new features as well. Highlights include:

  • Durable actor mailboxes (File-based transaction log, Redis-based, MongoDB-based, ZooKeeper-based and Beanstalk-based)
  • Richer API for Actor life-cycle management and invocation tracing
  • Improved Future API
  • Improved TestKit for testing Actor-based systems
  • Some API changes. For example 'sendRequestReplyFuture'/'!!!' renamed to 'ask'/'?' and 'sendOneWay' renamed to 'tell'

The full release notes for Akka 1.2 are available at the Akka project community site.

You can download the Typesafe Stack 1.1 from the Typesafe download page.

Finally, if you are at the JavaOne conference in San Francisco this week, be sure to stop by the Typesafe booth in the Java Pavilion in the Hilton East Lounge Lobby to learn more about Typesafe Stack 1.1 and other news from Typesafe.
