GLib introduced macros that allows defining the lower and upper bounds of the API to be used by application code. The lower bound allows to define the minimum version that will trigger deprecation warnings; the upper bound defines the maximum version that will trigger compiler warnings for unavailable symbols. This scheme allows gradually porting application code to a new version of the API, especially in case of resynchronization after multiple development cycles.
