ContextMenuPlus 1.1 was released for recovering preferences that was stored by version 1.0. ContextMenuPlus 1.0 used Add-on SDK 1.4 which had a bug that stored preferences in the wrong place.
This recovery will be done automatically and does not require any action from users. If you are using ContextMenuPlus 1.0, the only thing you need to do is upgrading it to version 1.1.
