Despite the Tails Calendar page[1] which says the release will now be on 2022-11-22, the files appear to be uploaded already. This is an UNOFFICIAL REPORT.
Often Tails images have appeared on mirrors a day or more previous to the official release date, which seems to be the case here. While I recommend waiting for the official announcement, I couldn’t help but share this discovery.
