Vaadin 6.2.0 is a major release that adds new widget packaging system, JSR-286 support and many new features. In parallel with the 6.2.0 version, a new version 1.1 of the Eclipse plugin is released.
Vaadin 6.2 makes packaging and integrating new widgets a breeze. Integration is as simple as dropping a widget.jar into your project. No more copying code, compiling manually with GWT, adding widget to a widgetset or editing XML.
Creating and packaging a new widget can be done with the help of new Eclipse plugin. You can practically create a widget and package it for use in other projects in 1 minute.
Other new features include Portlet 2.0 (JSR-286) support, OSGi support, generic client side event listening support, new Maven plugin, UI enhancements like Tabsheet closing and better tree styling, upgraded Sampler demo - and many others. For a complete list, see release notes.
Although the next generation of Vaadin Testbench is not officially released yet, we are using it internally to test Vaadin itself. Our automated nightly tests include currently over 1500 screenshot-based tests running on 7 different web browsers and 14 server environments. They ensure that all the UI widgets in Vaadin are kept pixel perfect regardless of changes to the other parts of the product.
