Jive Update 2016.1 had some pretty cool updates called "Content Evolution" that make most content types look more modern and that introduced a few minor changes to functionality. We'll be turning it on May 5th. A few buttons and filtering options in the community will change. Content authors will have the option to go back and do things like adding mast images to blog posts but for the most part you and your clients probably won't need to do anything.
