Thanks for the clarification, Phil, even though this is really bad news 
(for me at least).

Indeed, when it comes to compatibility, GPL v3.0 projects can include 
Apache v2.0 code, but the reverse is not true (see 
http://www.apache.org/licenses/GPL-compatibility.html).

In other words, by removing those exceptions in QScintilla 2.9 and 
later, you made Apache v2.0 projects unable to upgrade their copy of 
QScintilla, which I am sure must also apply to quite a few other open 
source licences.

Is there any chance you could do something similar to what the Qt 
Creator guys have done, i.e. release Qt Creator under GPL v3.0 with a 
couple of very simple excetions (see 
https://code.qt.io/cgit/qt-creator/qt-creator.git/tree/LICENSE.GPL3-EXCEPT)? 
Failing that, I guess I will have no choice but to revert to QScintilla 
2.8.4... :(
