As promised, the latest version of GWT has been released. You can download it from here.

Here are some of the new features (from the readme):

• FileUpload widget
  The much-requested file upload widget
• FormPanel widget
  Easily submit traditional HTML forms from GWT apps
• RPC optimizations
  Client and server performance improvements and a more compact wire format
• Automatic Resource Injection
  Modules can contain references to external JavaScript and CSS files, causing them to be automatically loaded when the module itself is loaded
• Internationalization
  Easily localize strings and formatted messages
• XML classes
  An XML library based on the W3C DOM
• JSON classes
  JSON has moved into gwt-user.jar, and it’s much faster than the sample that shipped with 1.0.21
• JUnit enhancements
  Unit tests are much, much faster than in 1.0.21, easier to configure, and you can now test asynchronous things like RPCs and timers
• Javadoc
  Now included for your convenience, with sample code fragments
• gwt-servlet.jar
  Although you should continue to build against gwt-user.jar as always, you only need to deploy gwt-servlet.jar with your webapps; it contains the subset of gwt-user.jar you’ll need to support RPC
