The latest round of plugin updates have just been released and made available to those who use them.

TinyMCE Editor

This release is an attempt to keep other WP plugins and themes from directly adding more buttons to the Simple:Press editor. Plugins blindly adding buttons to all TinyMCE instances can cause duplication issues in the forum. Hopefully, this will keep them from doing so automatically. They really should be only adding the buttons to the desired instances of TinyMCE.

As admin of your forum, you can still add any buttons they make available to your Simple:Press editor by adding their button names to the SP list of buttons to be used.
