GWT 1.5 isn't finished yet, but it is starting to get close. I'm happy to  report that the first milestone build of GWT 1.5 is now available. For milestone builds like this, please understand that there are still known  problems, and it is use-at-your-own-risk. It *definitely* isn't ready for
production use. For example, this milestone build is missing release notes,  and it doesn't include the developer guide documentation. So, you should expect some trial and error getting everything to work...

...I also have some good news about what's included in this milestone:

  • The Java 1.5 syntax is fully supported, including generics, enums, nice "for" loops, autoboxing, static imports, annotations, and so on
  • Support for generics in RPC (no more @gwt.typeArgs!)
  • The ability to subclass JavaScriptObject for very straightforward JavaScript interop
  • Standards mode is now supported by the UI library (though there may be a few remaining bugs)
