Scala 2.10.0 Milestone 5

Created by admin on 2012-07-13. Updated: 2012-07-13, 18:14

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-M5 includes many fixes and improvements, listed below.

Improvements included in 2.10.0-M5:

new, faster, backend enabled by default (emitting 1.5 classfiles unless -target:jvm-1.6 or -target:jvm-1.7 is specified)
Scaladoc pages now contain inheritance diagrams for classes and traits and content diagrams for packages. Look for “Type Hierarchy” and “Content Hierarchy” on the scaladoc page header (-diagrams is the flag to generate diagrams and you need the graphviz package installed)

Here's a list of isssues that have been fixed since v2.10.0-M4:
