Scala 2.7.3 RC2

Once again, a new release candidate for the next version of Scala is available: Scala 2.7.3 RC2 [1]. 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 [2]. An updated Scala plugin for Eclipse [3] is also available.
