Updated the distribution version of Seamless Donations from 3.3.4 to 3.3.5. This version added an upgrade warning admin message and a very big and very red box on the main Seamless Donations admin page letting folks know come here to get update information on the plugin as 4.0 coding progresses. Also added a MailChimp signup form to the 3.3.5 plugin so that current site operators can subscribe to this site and get notifications prior to when big changes are about to happen.
The 3.3.5 update propagates through the WordPress.org update mechanism and so existing plugin users will see a notice asking them to upgrade the plugin.
