We have released a variety of Add-On updates today. New versions of the AWeber, Campaign Monitor, FreshBooks, MailChimp, and Signature add-Ons being released via automatic update. The Signature Add-On has graduated from beta release status to full v1.0 release status.
One important update that has been made to all of these Add-Ons is they have been updated to provide support for the ManageWP service to make automatic updates fully compatible with ManageWP's update management system. ManageWP is a fantastic service for remotely managing and administering multiple WordPress installations.
