Upgrade gpa from GTK+ 2.2 to 2.4?

Hi gpa developers,

I wonder whether there is any reason not to upgrade the minimum version
of GTK+ 2.2 to 2.4. With 2.4 various new interesting methods have been
introduced.
Getting rid of any deprecated methods is also interesting, I guess.
Or is even GTK+ 2.6 something we can assume to be everywhere where gpa
aims for?

Best

	Jan
