Remove user from all roles not working

Hi,
Nice plugin but thought I would provide feedback on two items:
1. Any chance you can add support for the latest version of WP (as it does work in it)
2. I am not sure one of your FAQ is correct. I remove all roles and the update occurs but the User roles do not get updated. I suspect WP now requires at least one Group.
= Can you remove all roles from a user? =
Sure. The user will still be able to log in and out, but won’t be able to access any admin screens or see private pages. However, the user will still be able to see the WP Toolbar by default, which displays links to the Dashboard and Profile screens, so clicking on those will result in seeing a permission error.
