runner is no longer supported. [GL #4250]

6250. [bug] The wrong covered value was being set by
dns_ncache_current for RRSIG records in the returned

[GL #4154]

6204. [bug] Use NS records for relaxed QNAME-minimization mode.
This reduces the number of queries named makes when
resolving, as it allows the non-existence of NS RRsets
at non-referral nodes to be cached in addition to the
referrals that are normally cached. [GL #3325]
