Ubuntu previously was excepting Gnome point releases from major testing on the grounds that Gnome’s point releases are all big fixes and thus don’t require Ubuntu’s major testing process. Gnome shipped a new major feature in a point release and so Ubuntu said “oops, guess we gotta test their point releases after all”. Practically, it means Gnome point releases take longer to get into Ubuntu than they previously did (but are more tested for bugs).
