This leads to error retries\n        of 30s, 1 minute, 2, 4, etc. up to daily attempts.\n     - Checking that configuring `MDRetryDelay` will result in a positive\n       duration. A delay of 0 is not accepted.\n     - Fix a bug in checking Content-Type of responses from the ACME server.\n     - Added ACME ARI support (rfc9773) to the module. Enabled by default. New\n       directive \"MDRenewViaARI on|off\" for controlling this.\n     - Removing tailscale support. It has not been working for a long time\n       as the company decided to change their APIs.
