Have the best of both worlds. Construct elegant class hierarchies for maximum code reuse and extensibility, implement their behavior using higher-order functions. Or anything in-between.Learn More

Scala runs on the JVM, so Java and Scala stacks can be freely mixed for totally seamless integration.
So the type system doesn’t feel so static. Don’t work for the type system. Let the type system work for you!
Use data-parallel operations on collections, use actors for concurrency and distribution, or futures for asynchronous programming.
Combine the flexibility of Java-style interfaces with the power of classes. Think principled multiple-inheritance.
Think “switch” on steroids. Match against class hierarchies, sequences, and more.
Functions are first-class objects. Compose them with guaranteed type safety. Use them anywhere, pass them to anything.
We are very pleased to announce the release of Scala 2.11.4!
Scala 2.11.4 is a bugfix release that is binary compatible with previous releases in the Scala 2.11 series. The changes include:
:quitthe next time (see #3902). Kudos to @gourlaysama!
-Dscala.colorto enable that behavior (see #3993). Thanks to @puffnfresh!
The next minor Scala 2.11 release will be available before the end of the year, or sooner if prompted by a serious issue.
Serialization of anonymous functions in Scala 2.11.1 to 2.11.4 is affected by issue SI-8960. Normally, all anonymous function classes generated by the compiler have a
SerialVersionUID field of value
0l. The issue causes the
SerialVersionUID to be missing. This in turn causes the JVM to compute the UID from the class signature on deserialization, which may trigger a
ClassNotFoundException if the outer class of the function is not on the classpath.
Due to a binary incompatibility in Scala 2.11.3, we recommend upgrading to Scala 2.11.4, which resolves the incompatibility, as well as another blocker issue that was discovered in the days after the 2.11.3 release.
We have analyzed the mistakes that lead to the breakage (human error), and are taking measures to prevent this from happening again. We apologize for the inconvenience, and thank everyone who was involved in reporting and diagnosing these critical issues.
A large number of Scala projects have been released against Scala 2.11. Please refer to the list of libraries and frameworks available for Scala 2.11.
A release of the Scala IDE that includes Scala 2.11.4 is available on their download site.
The release notes for the Scala 2.11 series, which also apply to the current minor release, are available in the release notes for Scala 2.11.1. They contain important information such as:
A big thank you to everyone who’s helped improve Scala by reporting bugs, improving our documentation, participating in mailing lists and other public fora, and submitting and reviewing pull requests! You are all awesome.
