Scala IDE 4.0.0-M3

###### By Scala IDE team on Jul 24 2014 <h1 id="the-third-milestone-for-scala-ide-400">The third milestone for Scala-IDE 4.0.0</h1>

We are very happy to announce the third milestone release of Scala-IDE 4.0.0 ! We are making significant steps towards our Lithium release, with cool features along the way.

Don’t forget those milestone releases are there for you, users, to help work out the possible kinks. So, try them out, and let us know what you think ! You’ll find out how to do that on our community page.

There are two major new features in this milestone:

  • redesigned support to work with a “hot-swappable” Scala version. The IDE now lets you not only choose which Scala version you want building your projects, but it also lets you plug in your own custom Scala Installation. This integrates with the 2.10/2.11 Scala version support, so that a single version of the IDE lets you work on both Scala 2.10 and Scala 2.11 projects.

We have written a blog post detailing this feature.

  • a New Scala File Wizard! We have a new interface for creating new Scala Classes, Traits, … It’s minimalistic, and removes everything that’s not needed for hacking in Scala. It’s also more extensible. Have a look at the blog post to learn about it. We think you’ll like it !

Also, note have an updated documentation section for the upcoming 4.0.0.

Other Highlights

This release fixes many bugs, and we invite you to read the Changelog for a full description. Here are some interesting excerpts:

  • a redesigned Bug Report Dialog
  • new extraction refactorings, such as Extract Value, Local, Method, Parameter, Closure, …
  • the IDE now shows a value on variable hover in suspended Debug mode
  • a fix for auto-breaking comment lines
