For example, many memory leaks have been fixed in PyGObject 3.8 Beta 2, making it much stable than the previous versions. Moreover, the GValue.get/set_value function has been optimized by settings GValue.g_type to a local.
Tests are now executed with G_SLICE=debug_blocks, compilation support on Visual C++ has been fixed, Widget.window, scroll_to_mark and window methods have been added to pygtkcompat, and original GTK/GDK functions are no longer clobbered with overrides.
