There is a new version of the GWT Widget Library out. This looks like mainly a bug fix release. From the homepage:

• Patch GWTSpringController for missing interface (George Georgovassilis)
• Patch LightBox for browser resize issue (Jason Paignigiannes)
• Patch LightBox for GWT 1.1.10 transparancy issue in IE (Robert Hanson)
• New constructors for CalendarPanel which take a date (Robert Hanson)
• New methods for CalendarPanel to set current month (Ilia Pritzker)
• Deprecated GWTSpringController, it is now part of the GWT Server Library

Robert Hanson has also announced the first release of the GWT Server Library.

This is our first release of a server only distribution for GWT. It currently contains the latest version of the GWTSpringController as well as the new GWTHandler, both of which are the work of George Georgovassilis.
