Scala 2.7.3 RC2

Once again, a new release candidate for the next version of Scala is available: Scala 2.7.3 RC2. This release candidate is almost identical to the previous RC1, except for a couple of last-minute bug fixes. We expect a final release very shortly. Scala 2.7.3 is a maintenance release, while work progresses towards the upcoming Scala 2.8. Please read below for further details.

You can download Scala 2.7.3.RC2, as usual, from our Download Page. An updated Scala plugin for Eclipse is also available.
