The endpoint now returns room rates for shoulder dates in addition to core group stay dates. Shoulder dates are dates outside the main group stay window configured in the PMS. Each date in the response includes a new is_shoulder_date boolean flag to distinguish shoulder dates from core dates. If no shoulder dates are defined for the group, only core stay dates are returned.
