2.0.15

• Remove enable-overloading flags, and use instead explicit CPP checks for 'haskell-gi-overloading-1.0', see how to disable overloading.

2.0.15

• Fix introspection info for pixbufNew, pixbufCopy, pixbufCompositeColorSimple and pixbufScaleSimple. The return values in all these cases can be null, but were not marked as such. See https://github.com/haskell-gi/haskell-gi/issues/127.
