I received the following email from the plugin:
Automatic Updater just ran on your site, http://www.limecanvas.com, with the following result:
We found a plugin upgrade!

Thanks for using the Automatic Updater plugin!
However, the plugin remains at the old version ( see http://awesomescreenshot.com/037pzmo16 )
