# The following version number definitions apply to GLib, GModule, GObject,
# GThread and GIO as a whole, so if changes occurred in any of them, they are
# all treated with the same interface and binary age.
#
# Making releases:
# glib_micro_version += 1;
# glib_interface_age += 1;
# glib_binary_age += 1;
# if any functions have been added, set glib_interface_age to 0.
# if backwards compatibility has been broken,
# set glib_binary_age _and_ glib_interface_age to 0.
#
# remember to add a GLIB_VERSION_2_xx macro every time the minor version is
# bumped, as well as the GLIB_DEPRECATED_IN and GLIB_AVAILABLE_IN macros
# for that version - see gversion.h for further information.
#
# in easier to understand terms:
#
# <mclasen> on the stable branch, interface age == micro
# <mclasen> on the unstable (ie master), interface age = 0
