Oh. Never mind. The update notification went away after a few minutes.
Though the issue about the licence key in wp-config with no UI enabled may catch a few people out.
@elliot. Thanks. That seems to have fixed the problem, but you really should have updated the version number!
I need to keep old versions of plugins around in case there are issues with a newer version and I need to revert (you don’t seem to provide links to old versions). Having two different version of the plugin with the same version number does not help.
