  We're going to go ahead and take both of those changes that were considered
  in /testing. GazL almost had me talked out of the autogroup change, but it's
  easy to disable if traditional "nice" behavior is important to someone.

  This update fixes bugs and the following security issue:
  The "lame-ttl" option is now forcibly set to 0. This effectively disables
  the lame server cache, as it could previously be abused by an attacker to
  significantly degrade resolver performance.
  For more information, see:
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-25219
