Hello,
I'm excited to announce second milestone of Scala+GWT project.
Download (and then follow README instructions) from here: http://goo.gl/93hsR
Release notes (included below) can be found here: http://goo.gl/H8san

Scala+GWT 0.1-M2----------------
The second official milestone release from the Scala+GWT project.
You can check release notes for Scala+GWT 0.1-M1 [here](http://scalagwt.github.com/releasenotes).
This release consists of just samples packaged along with snapshotof jars needed to build them. Those jars include our own versionof both GWT and Scala.
This release doesn't come with any official artifacts apart from the tarball you can download from [http://github.com/scalagwt/scalagwt-sample)" rel="nofollow">http://github.com/scalagwt/scalagwt-sample](http://github.com/scalagwt/scalagwt-sample).
### Changes since last release
  * Vastly improved compilation speed  * No more issues with GWT classpath thus build process for samples got simplified  * Development mode works
### Development mode
GWT's development mode is supported for Scala project now. You can get simple versionof development mode by running `ant devmode`. Then load your application using the url GWT provides. Change edit source code for Hello world sample and then type`ant scalac` in second terminal. Refresh your page in browser. You should see yourchanges.
Read more about [development mode](http://code.google.com/webtoolkit/doc/latest/DevGuideCompilingAndDebugging.html#DevGuideDevMode).
Watch [video](http://www.youtube.com/watch?v=w1nluQmkE8g) showing full-blown development mode for Scala.
### Known issues
  * many patterns in pattern matching logic are not supported (tough issue) examples include    * pattern alternatives (`|`)    * guard patterns (`if` guard)  * in some cases (like gwtdlx sample) optimizations enabled in gwt lead to broken JS code
### Reporting issues
We appreciate feedback. If you find something that doesn't work (e.g. crashes either Scala or GWT compiler)or JavaScript gives you weird results we'd love to hear about it. The most effective way of reporting issues is to modify `Hello World` sample to show your problem. Exact steps are:
  1. Fork `scalagwt-sample` repo from here: http://github.com/scalagwt/scalagwt-sample   2. Clone it: `git clone git://github.com/YOUR_USER_NAME/scalagwt-sample.git`  3. Modify hello world sample located in `src/com/google/gwt/sample/jribble/client`   4. Commit and publish your example.  5. File a ticket here: http://github.com/scalagwt/scalagwt-sample and mention your     fork while explaining your issue.
If you want to discuss your problem before reporting it, join[scalagwt [at] googlegroups [dot] com](http://groups.google.com/group/scalagwt).
### What if I don't know GWT?
That shouldn't be a big problem. You've got Scala source code for samples that show basic functionalityand provides basic setup. You may want to start with channging hello world sample, recompiling it and testing in a browser.
### What if I don't know Scala?
You might still want to check out samples to see how they might look like in other language than Java. We'll be cutting a lot more of boilerplate code once GWT libraries and APIs receive enough of Scala's[pimp-love](http://www.artima.com/weblogs/viewpost.jsp?thread=179766).
### Need help? Want to discuss something?

Happy playing!
