In order to ensure a smooth migration of 3.x plug-ins running on top of a 4.x base, there are several things that need to be checked to prevent headaches further down the road.

APIs and Internals

As detailed on the limitations of the Compatibility Layer, the org.eclipse.ui.presentations API has been removed and the org.eclipse.ui.themes extension point is being ignored for some select cases. These references should be searched for to ensure that they have been refactored out into a separate bundle to prevent problems when using the original plug-in on a 4.x base.

The org.eclipse.ui.actionSets extension point has been deprecated in the 4.x stream. While they may still be used on 3.x, it is recommended to migrate code that uses the actionSets and objectContributions extension points to the Eclipse 3.3 org.eclipse.ui.menus extension point.
