IT House December 23 news, this morning, Apple announced that the Apple Developer certificate is about to be updated. The media certificates for Apple Push Notification Services (APNs) and Developer IDs will be updated from January 27, 2022.

Among them, APNs SSL certificates will be issued by a new media certificate specifically for APNs (Worldwide Developer Relations G4 sub CA). When the new certificate is activated and available for download, developers can use it to send push notifications to apps (including VoIP), complications, safari websites, and Apple Wallet passes.
IT House understands that the digital certificates that developers use to sign software and installation packages on macOS will be issued by a new Developer ID media certificate that expires on September 16, 2031.
Newly issued Developer ID certificates associated with the new media certificate can be used to sign software on Xcode 11.4.1 and later. If the developer is running Xcode 13.2 or later, the updated certificate will be automatically downloaded when the software is signed after January 28, 2022. If the developer is using an earlier version of Xcode, they can download the certificate manually or create a certificate that is compatible with the previous version of Xcode.
Apple said the developer's existing certificate will remain valid until it expires or is revoked, whichever expires first.
