  dnsmasq (2.86-1.1ubuntu0.2) jammy; urgency=medium

  * src/forward.c: Do not refuse retries from client DNS queries. Behaviour to
    stop infinite loops when all servers return REFUSED was wrongly activated
    on client retries, resulting in incorrect REFUSED replies to client
    retries. The code added here is a cherry pick released in upstream version
    2.87, originating at
    (LP: #1981794)
