None of the problems you reported pertained to extra parameters
required during initialisation _and_ GTK.  I was referring to the
problems you reported that referenced GTK.

The NEWS file in git is the source of the news files.

The commits in git are more detailed, but there are many of them.
I've briefly iterated through them but haven't found anything
obvious.  Perhaps it is changes to GObject that caused some of these
problems.
