Scala 2.7.2 RC4

After some final ironing and bug fixing, a new release candidate
for the next version of Scala is available: version 2.7.2.RC4.
As usual, the updated Scala plugin for Eclipse is available
via the Eclipse software update facility; further information
is available at: http://www.scala-lang.org/node/94
The new Scala 2.7.2.RC4 is available for download from our
download page at: http://www.scala-lang.org/downloads

What's new in Scala 2.7.2?

* Generic Signatures

   The Scala compiler now generates Java's generic
   signatures, so that Scala generics are visible to Java.

* Java/Scala Combined Projects
   The compiler can now parse (but not translate) Java source
   files. This makes it possible to have mixed Java/Scala
   projects with recursive dependencies between them.
   In such a project, you can submit first all the Java and Scala
   sources to the Scala compiler. In a second step, the Java
   sources are compiled using the Scala generated .class files
   and the Scala sources are compiled again using the Java
   generated .class files.

* ScalaSwing
   Another major addition is the first beta version of the
   ScalaSwing library, which is now bundled with the distribution.

* Scala Collections
   There are new implementations of collection classes, contributed
   by David MacIver: IntMap, LongMap, and TreeHashMap (immutable),
   ArrayStack and OpenHashMap (mutable).
