A while back, someone reported that maybe WP NoteUp wasn’t working in the latest 4.7. Turns out there was major thing going wonky. First off, the content was totally lost when the metabox was moved from the side panel to the “normal” section.
But, that’s been fixed and now the NoteUp panel simply isn’t draggable to the side anymore, leaving your content un-harmed. Minor change, but should be working in WP 4.7.2!
Also there were some activation issues, code cleanup, and cleaner code deployed to SVN. You can read all about it. Thanks to @WebDevStudios (who I work for) for allowing us to give back 5% of our time to WordPress for #5ftf!
