Feature Description

As the major release 3.0.0 will remove almost all modules in favor of their standalone plugins and a new UI exposing controls for them, we should notify administrators already before the update that the release will include this major change. This can be accomplished by adding an upgrade notice for that release to the readme.txt file.

Requirements

• An == Upgrade Notice == section should be added to the readme.txt, with a = 3.0.0 = sub section that includes a message informing about the upcoming change and that the user will be asked to install/activate the standalone plugins instead of the previously used PL modules.
