ANN: Scala 2.11.0-RC3 is out!

[Adriaan Moors]

We are very pleased to announce Scala 2.11.0-RC3, the second (sic) release candidate of Scala 2.11.0! Download it now from scala-lang.org or via Maven Central.

Please see GitHub or scala-lang for the full release notes. A summary is included below.

There won't be an RC2 release because we missed a blocker issue (thanks for the reminder, Chee Seng!). Unfortunately, the mistake wasn't caught until after the tag was pushed. Jason quickly fixed the bug, which is the only difference between RC3 and RC2.

Please do try out this release candidate to help us find any serious regressions before the final release. The next release candidate (or the final) will be cut on Friday March 28, if there are no unresolved blocker bugs at noon (PST). Our goal is to have the next release be the final -- please help us make sure there are no important regressions!

Code that compiled on 2.10.x without deprecation warnings should compile on 2.11.x (we do no guarantee this for experimental APIs, such as reflection). If not, please file a regression. We are working with the community to ensure availability of the core projects of the Scala 2.11.x eco-system, please see below for a list. This release is not binary compatible with the 2.10.x series, to allow us to keep improving the Scala standard library.

For production use, we recommend the latest stable release, 2.10.4.

The Scala 2.11.x series targets Java 6, with (evolving) experimental support for Java 8. In 2.11.0, Java 8 support is mostly limited to reading Java 8 bytecode and parsing Java 8 source. Stay tuned for more complete (experimental) Java 8 support.

The Scala team and contributors fixed 601 bugs that are exclusive to Scala 2.11.0-RC3! We also backported as many as possible. With the release of 2.11, 2.10 backports will be dialed back.

Since the last RC, we fixed 54 issues via 37 merged pull requests.

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 -- of course -- submitting and reviewing pull requests! You are all awesome.
