Along the lines of what AlexPM said - It does feel a little strange that Lithium is "strongly recommend testing your message editor" without giving more guidance on what to test. I just copied out the list of changes from TinyMCE v4.4.3 --> v4.7.13, and it spans 27 pages (feel free to take a look at this list; here's the Google doc)
Lithium, what did you test when you upgraded TinyMCE? Are there specific areas that seemed like they might be problematic based on different custom themes? A bit of guidance here would be appreciated. I totally understand that you got a "balloon payment" of TinyMCE code - but at the same time, if you "strongly recommend we test," I'd like to have some idea of what to test / what you tested.
