Apologies.  I got so excited about the upgrade, I prematurely sent the email.

The gerrit server on review.trustedfirmware.org will be offline for a 2 hour maintenance window starting today (Oct 3, 2023) at 19:00 UTC.

This downtime is needed in order to upgrade gerrit to the current version.

Changelog is available at:
