        Dear developers,


        A new certificate for server-based Game Center verification is available via the publicKeyUrl property of generateIdentifyVerificationSignature, and the previous certificate will no longer be available after September 17, 2019.


        The new X.509 certificate URL returned by publicKeyUrl will be https://static.gc.apple.com/public-key/3rd-party-auth-prod-19824d.cer. Both the new certificate and prior certificates use SHA256withRSA.


        Avoid storing the certificate or hardcoding the certificate URL, as this will require an app update when the certificate expires. Instead, make sure your app always retrieves and uses the current publicKeyUrl value so it automatically uses the latest certificate.
