In reply to Justin Tadlock.

Apologies, I missed that it was the Post tab - that does seem a little overzealous. At least it's related to the settings for the post itself, or at least what the settings could be if you upgraded, and there's a way to turn it off (at least until you do a hard refresh).

I definitely try not to be that in your face and only put upgrade messages in the context of settings for the plugin itself. I don't want to risk the potential 1-star reviews :)
