Change: Now, if only port without IP is specified (default value) in the acme_http_port directive and there are server blocks listening on that port, HTTP challenge handling for the port in ACME is working only on the IP addresses configured in the listen directives of these blocks; there will be no attempt to listen on all IP addresses, like it was before; this makes configuration more flexible and prevents the issue with updating from previous versions with configurations where there were only server blocks listening on port 80 and particular IP addresses.
Bugfix: HTTP/2 requests were not counted in server zone statistics; the bug had appeared in 1.11.0.
Bugfix: When an ACME client was disabled in the configuration and had no previously obtained certificate, a statistics API request for that client could crash a worker process.
Bugfix: If the $http_host or $cookie_* variables were used as keys in the status_zone directive within the server block, HTTP/3 requests might not be counted in this status zone.
