We're happy to announce our first release candidate for Google Web Toolkit 1.2, which has a number of highly requested features and bug fixes:
  • Full support for OS X development
    Develop with GWT on OS X as easily as on Linux and Windows
  • Much faster hosted mode
    Debug your GWT apps much more quickly. Hosted mode startup time has improved significantly -- and even better, refreshes are now lightning-fast -- even when your source code changes.
  • New HTTP request module
    The HTTP functionality that you've been asking for (custom headers, status code, timeouts, and more), all wrapped up in an API that's easier to use than the JavaScript XMLHttpRequest object
  • Widgets in TreeItems
    Tree items can now contain arbitrary widgets -- finally, it's easy to create trees with checkboxes :-)
See the GWT issue tracker for the complete list of enhancements and bug fixes in this release. You can download GWT 1.2 RC1 and all previous versions of the product on the GWT website.

As I mentioned in my last post, we are launching this Release Candidate build of Version 1.2 so that we can get bug reports and feedback from GWT developers. We will follow up with the final 1.2 release in a few weeks once we have fixed all of the major issues in the Release Candidate. So keep those bug reports coming, and let us know if you have any issues with the release in the GWT Developer Forum.
