At long last, Google Web Toolkit (GWT) 1.4 Release Candidate 2 is now available for download. Though it has taken some time since 1.4 RC1 was released, we've fixed nearly 100 bugs since then. This may well be the best and most solid GWT release to date, and we expect this build will become the final 1.4 release. Still, until we designate a "final" 1.4 release, we strongly recommend against using it in production applications. If you run into problems, please let us know in the issue tracker. And if you don't run into any problems, please take a moment to thank all of the GWT open source contributors who have made such a big impact on GWT 1.4. :)
Looking ahead, we plan to start on GWT 1.5 quickly, the main thrust of which will be Java 5.0 language support and all that entails. We intend to make a wholesale shift to 5.0 syntax for all GWT client code; with luck this won't be problematic, since Java 5.0 syntax is largely backwards compatible. An open question is whether we will continue to produce Java 1.4-compatible server-side components. Feel free to join in the discussions on the Developer Forum.
