苹果推送通知服务器证书更新

过完年回来收到了这封邮件：

On March 29, 2021, token and certificate-based HTTP/2 connections to the Apple Push Notification service must incorporate the new root certificate (AAACertificateServices 5/12/2020) which replaces the old GeoTrust Global CA root certificate. To ensure a seamless transition and to avoid push notification delivery failures, verify that both the old and new root certificates for the HTTP/2 interface are included in the Trust Store of each of your notification servers before March 29. 

Note that Apple Push Notification service SSL provider certificates issued to you by Apple do not need be to updated at this time. 

咨询了下第三方推送平台。
移动端不需要重新生成推送证书，极光推送已经对HTTP/2做了支持。
