General loss of class, method and namespace detection in version 8

Since upgrading to verion 8.0.1, PHPStorm seems to have lost the ability to properly detect namespaces, classes and methods for auto-complete and code navigation.

For instance, all of the items in the screenshot were correctly detected under v7.1 so I could just ctrl+click on them to navigate through the code:

What happened with the upgrade?

BTW, using Laravel 4.2 in this example.
