Google Web Toolkit 1.4 available

Google Web Toolkit 1.4 has been released. GWT is a tool to develop AJAX applications in Java. You don't write any Javascript: it gets generated from your Java code thanks to a Java to Javascript compiler. When in "hosted mode" your app runs on the Java Virtual Machine, which gives you access too all available Java debugging tools and techniques. This release is a major upgrade, and features improved performance.
