Version 2.7.5 of Scala
Release Notes: This release fixes bug #1999 (a starvation problem when many tasks are created from an FJTaskRunner thread). This could result in the JVM running out of memory. It fixes bug #2000 (Linked actors do not always terminate properly). This could result in memory leaking in applications that create many linked actors. It disables reference-counting actors using WeakReferences, since this could lead to memory leaks; a different scheme is used. A NullPointerException bug in Scheduler.restart has been fixed.
Other releases

The Scala Swing libraries, the REPL, implicits, equality, the XML library, annotations, Sbaz and Scalap, and compiler speed were improved. Actors were enhanced. Packrat parser combinators, continuations, a new build manager, and a new Scaladoc tool were added.

Release Notes: This minor maintenance release addresses one rare issue that could result in a "malformed Scala signature" message. No other fixes or changes are included; if you have never encountered the message above, you will not notice any difference by upgrading.
