Google Web Toolkit Gets Update, Unofficial Leopard Build Also Released

Google has released Google Web Toolkit 1.4.61, a minor update to its open-source AJAX development environment. The company has also released an unofficial build for Mac OS X 10.5 ("Leopard").

Google Web Toolkit is an open-source Java development framework designed to provide a simple set of tools for building Web applications in AJAX. It provides libraries for use in various Java IDEs and a compiler for churning out JavaScript and HTML. The software provides reusable UI elements, debugging, browser history management, support for Google Gears, and JUnit integration, among other features.

The new 1.4.61 release updates the framework with minor bug fixes, including a security issue that was found in the previous release (related to the benchmark reporting system) and a fix for errors during startup on IE6/7.

In addition, Google has released an unofficial 1.4 build for Mac OS X Leopard that includes changes to the hosted mode browser "to account for differences between Tiger and Leopard," according to Google. The compiler for the Leopard version is the same as the production build, and Google said the unofficial release "will produce applications that can be safely deployed into production."

Google Web Toolkit is available free under the Apache 2.0 open-source license and supports Mac OS X, Windows, and Linux. (Users can also create their own builds from the source code.) A link to the unofficial release for Mac OS X 10.5 can also be found below.
