[2018-01-05] api2, api4 TLS certificate renewal

On Friday 5th January 2018, we will renew the TLS certificates for api2.yubico.com and api4.yubico.com.

No service interruption is expected. If you have hard coded the CA or certificate fingerprint (not recommended), you will need to update your hard coded information.

We will write a new post once the renewal has taken place.
