[Plugin: The Welcomizer] Does 3.1 compatibility exist?

Hi there and thank you for an excellent and unique plugin.
The updates you provide keep pouring in. And most of them are additions and not bug fixes. That (to me at least) means good code knowledge.

But although wordpress 3.1 is in the air you have NOT changed the plugin’s compatibility. Is there a reason for that?
