[CalendarServer-users] Calendarserver Patch for New APNS HTTP/2 Protocol?

Does anyone have a calendarserver patch that addresses the new APNS API requirement for HTTP/2? I just swapped in new APNS certificates and see in the calendarserver logs that APNS connections are no longer going through. The legacy APNS binary protocol was deprecated in November 2020: https://developer.apple.com/news/?id=11042019a&1572897862
