Scala 2.10.0 Milestone 6

Created by admin on 2012-07-31. Updated: 2012-07-31, 17:00

A new milestone release for Scala is available. This release is cut directly from current development and is not intended for production environments, but is a great chance to try out the up and coming features for Scala 2.10.0. The milestone 2.10.0-M6 includes many fixes and improvements, listed below.

 

New in this milestone:

  • Akka actors jar now included in distribution.
  • Backend emits Java 1.6 class files by default. Generation of Java 1.5 class files has been deprecated. Non-default class file formats can be emitted via -target:jvm-1.5 and -target:jvm-1.7.

 

Here's a list of isssues that have been fixed since v2.10.0-M5
