gi-gstvideo-1.0.16: ChangeLog.md

### 1.0.16

+ Do not generate bindings for `VideoOverlay.installProperties`, since we don't support class structures yet.

### 1.0.15

+ Remove enable-overloading flags, and use instead explicit CPP checks for 'haskell-gi-overloading-1.0', see [how to disable overloading](https://github.com/haskell-gi/haskell-gi/wiki/Overloading\#disabling-overloading).
