GWT 1.2 RC1

The GWT team has announced the first release candidate for Google Web Toolkit 1.2 with Mac OS X support. As stated in the GWT blog, GWT 1.2 RC1 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 :-)
