We are happy to announce the first release candidate of the new Scala distribution: Scala 2.9.1 RC1 is now available from our Download Page. This is a maintenance release: several bugs have been fixed, and other improvements introduced. The new release is intended to be fully binary compatible with the existing version 2.9.0.1.

Please help us testing this new release candidate, and let us know of any issues you may detect, or of any binary incompatibility issue that you may encounter. A description of the improvements in Scala 2.9.1 is available below.

The Scala 2.9.1 distribution

This Release Candidate is made available for testing purposes only and is not intended for production environments. We will wait at least two weeks before issuing a final release, in order to allow developers and testers to send us their feedback.
