As always, when upgrading from an earlier version, you should recompile any custom widget sets and refresh your project in Eclipse. Notice that Vaadin 6.2 uses GWT 2.0 (included in the installation package). See the
General Upgrade Notes
for more details on upgrading.

add-on. The long-awaited component was originally scheduled for Vaadin 6.4, but was left as a separate component until it matures. It may be incorporated into the core library in some later release.
