A fairly minor milestone on the road to Scala’s next version, but check out the number of projects popping up

The next milestone in Scala’s long road to the 2.10 version has
arrived, showing signs of a general cleanup for the language as it
prepares for the full release.

We won’t have to wait too long now for the big day with only two
new features present this time round, indicating that it’s nearly
ready for us to test out. As ever, this release is cut
directly from current development and is not intended for
production environments. The Akka actors jar is now included in the
distribution, whilst the backend emits Java 1.6 class files by
default, with Java 1.5 class files deprecated.

The majority of Scala developers have been entrusted to go on a
bughunt, with 60 bug fixes tackled, all of which can be found
here in the
announcement
.

The multi-paradigm language is on the cusp of breaking
free of its ‘hipster’-ish shackles for an assault on the
mainstream. The best indication of that is the amount of Scala
projects now cropping up, all 22 of them offering a release
alongside this version. There seems to be an audio theme of the
ones listed below:

  • scala-arm - provides automated resource
    management to ensure all your resources are closed without all the
    extra work!
  • scalaz - for type classes and pure functional
    data structures
  • ScalaInterpreterPane - the Swing based
    front-end for the Scala REPL (interpreter)
  • AudioWidgets - specialized Swing widgets for
    audio applications in Scala
  • ScalaAudioWidgets - wrappers for the library
    above
  • ScalaAudioFile - read and write uncompresed
    audio files
  • ScalaOSC – a library for OSC, a message
    protocol used in multimedia apps.
  • ScalaCollider - a sound synthesis library
    for the SuperCollider server
  • ScalaColliderSwing - Swing and REPL
    front-end
  • FingerTree - a Scala implementation of the
    data structure
  • Scala-IO Core - speaks for itself
  • Scala-IO File – idomatic filesystem
  • shapeless - an exploration of generic
    programming in Scala
  • SLICK - Scala Language Integrated
    Connection Kit
  • specs2 - library for executable
    specifications in Scala
  • ScalaTest - the established method for testing
    Scala applications
  • ScalaMock - native mocking with macros added
    in
  • Scales Xml
  • parboiled -  lightweight yet powerful
    parsing 
  • scalalogging - performant logging
  • scala-stm - transactional memory

Add to that the jewel in the crown, the Akka platform for
building superb event-driven applications on the JVM, and you’ve
got a pretty thriving community. This is no thanks in part down to
the last version where big strides were made but now many more
developers are seeing the charms of the language. Looks like Scala
is making the right noises moving forward.
