This year's release, internally being called the July 2010 release, is the most stable version yet, and Eclipse plugin makers should use it to test backward compatibility and migrate their plugins and RCP apps.
New in e4 0.10
Open Social - Parts of this spec have been implemented and many existing gadgets should work. These gadgets can now be opened as views in Eclipse.
XWT - The JFace viewer now has a simplified declaration and XWT provides a transparent "Declarative Data Binding" solution to hide the complexity of JFace data binding. XWT supports the creation of Eclipse forms, and the e4 workbench is now able to provide automatic state management. This release also includes initial integration with Trident (an animation engine for Java).
Here is the example Snippet017 of Jface Data binding ported in XWT:
XWT Tooling - The new XWT tooling includes a Visual Designer (WYSIWYG).
Workbench Tooling - This tooling comes with an advanced workbench model editor. You can edit the model at design time or edit a live model. It also has integration with JDT and a new WYSIWYG visual designer.
Resources - The Semantic File System (SFS) can now work with non-file-system-based content. SFS also integrates with aspects of the Eclipse Team support
