ScalaTest 1.7.2 and 1.8.RC1 released
Hi All, I made two ScalaTest releases this week, 1.7.2 and 1.8.RC1, for Scala 2.8.1+ and 2.9.0+. 1.7.2 fixes a bug in our sbt integration which caused a thread to leak, and includes a small change to facilitate use with Play 2.0. ScalaTest 1.7.2 should be binary compatible with 1.7.1, so you can just drop it in. Info on how to get it is here: http://www.scalatest.org/download ScalaTest 1.8.RC1 is the first release candidate of a fairly major release. Much of what 1.8 contains was originally planned for ScalaTest 2.0, but since 2.0 has taken a long time to complete I decided to release 1.7 and 1.8 as milestones on the road to 2.0. ScalaTest 1.8.RC1 should be source compatible with ScalaTest 1.7.1 (and 1.7.2), so please let me know if something breaks for you. It is not binary compatible, so you'll need to do a clean build, but that should be all that's required to upgrade. Please post on scalatest-users if you encounter a problem. ScalaDoc for the 2.9.0+ variant is here: http://www.artima.com/docs-scalatest-1.8.RC1/ This release includes quite a few enhancements, and some bug fixes and deprecations. Best place to see a rundown is on the release notes, which includes links to the relevant ScalaDoc: http://www.scalatest.org/release_notes#release18(Continue reading)

Eclipse Scala IDE 2.1 Milestone 1 released!
Today we released an early preview of the Scala IDE V2.1 for Eclipse! While the goal of V2.0 was to provide a reliable environment for your Scala coding, with V2.1 we want to bring your Scala development experience to a whole new level.
In this milestone there are a whole lot of new features for you to try out: implicit highlight, move refactoring, scala debugger and semantic highlight are the most exciting ones. If you are like us, once you start using them you will no longer be able go back. They are simply too addictive!
Let’s have a quick round at the new available features.
Implicit Highlight
Implicits are a powerful Scala construct, but it is often hard to guess when they are applied. With implicit highlight you get immediate visual feedback in the editor and, by pressing Cmd/Ctrl+1, you can turn an implicit conversion into an explicit call. Read more…
Mantra: de-obfuscate code!
Move Refactoring
There is a new refactoring available in your toolbox. Move refactoring will let you move a source file between packages or extract a class/object/trait definition (from a file with multiple definitions) and move it to a new location. And, of course, it will make sure to keep your imports sane. Read more…
Forget copy/paste!
Scala Debugger
You have been asking for better debugging support, we have been listening.
A few weeks ago we started to work on a full-fledged Scala Debugger and today you can have an early look at what is going to offer. As of now, you can already step through closures and have a Scala-aware display of debugging information. Read more…
Profit.
Semantic Highlight
Semantic highlight colors identifiers based on their meaning, which goes a long way into improving readability. All the contextual information about identifiers are available right at the usage site, which means you no longer need to jump to the declaration to tell what kind of Scala element you are looking at. Read more…
Embrace semantic highlight and say “au revoir” to the old habit!
A glance at the future
While we are really excited about this milestone, we are already working on the next “big things” planned for V2.1. One important addition is the creation of an API to ease the development of plugins on top of the Scala IDE. We are confident that this will incentivize developers, and hopefully we will soon have an exciting plugins’ ecosystem.
Have a look at the Roadmap and see what is planned next.
Install it now!
Follow this link and grab the update-site!
This milestone is available only for Scala 2.9 and it works with Eclipse 3.7 (Indigo). We developed and tested it using Java 6, but Java 7 can be used with some caveats.
We hope you will enjoy using it and, please, let us know what you think. This is the perfect time to help us with ideas and improvement suggestions, or just contribute them.
Thanks
We would like to take the opportunity to thank all contributors for the amazing work they have done to make this milestone possible. Special thanks go to David Bernard, Luc Bourlier, Mirco Dotta, Iulian Dragos, Jeremy Heiner, Dan Kilman, Heather Miller, Jin Mingjian, Eric Molitor, Martin Odersky, Hubert Plociniczak, Matt Russell and Mirko Stocker.

MapperDao ORM 1.0.0-rc5a with lazy loading, memory caching
MapperDao is an ORM library for Scala with drivers for the following databases:
- oracle
- postgresql

- sql server
- h2
The new version includes configurable lazy loading (along with skip-loading) of related data, configurable memory caching via EHCache and simplifications to entity mappings.
Other features of the library include persistence of immutable entities, mapping legacy code (hibernate, jdbc etc) via "external entities", type safe queries via a dsl that resembles select statements and it can also be used as an ORM tool for Java projects.

Eclipse Scala IDE 2.0.1 released!
We are very happy to announce the final release of the Scala IDE for Eclipse V2.0.1.
This is a maintenance release containing only bug fixes, upgrade is recommended for all users.
What is new in 2.0.1?
Builder improvements
In 2.0.0 the IDE delivered better incremental compilation by building on the already proven Sbt incremental compiler. In 2.0.1 we improve on the Eclipse builder by following Sbt more closely when dealing with dependent projects:
- when a project has build errors, dependent projects are not rebuilt
- fine-grained information about changes in a project are propagated to downstream dependent projects, leading to even less files being recompiled
In 2.0.1, the Eclipse builder compiles exactly the same number of files at the command line Sbt.
Editor improvements
We fixed a couple of small, but annoying editor issues: double braces are inserted and deleted together, completions that need an additional import won’t mess up the file, and Open Declaration works when called from the contextual menu.
Compiler improvements
This release is based on Scala 2.9.2, and includes a couple of improvements in the way compiler plugins are loaded, including the continuations plugin. Now you can have several compiler plugins loaded side-by-side, and properly use the Xpluginsdir option.
For a complete list of changes, please see the Changelog
The fine print
This version works with both Eclipse 3.6 (Helios) and 3.7 (Indigo). We developed and tested it using Java 6, but Java 7 can be used with some caveats.
