 Bug Fixes
 ~~~~~~~~~
 
-- Fix the default interface-interval from 60s to 60m.
+- Correct the default :any:`interface-interval` from 60s to 60m.
 
-  When the interface-interval parser was changed from uint32 parser to
-  duration parser, the default value stayed at plain number `60` which
-  now means 60 seconds instead of 60 minutes.  The documentation also
-  incorrectly states that the value is in minutes.  That has been fixed.

-- Fix purge-keys bug when using views.
+- Fix a :any:`purge-keys` bug when using multiple views of a zone.
 
   Previously, when a DNSSEC key was purged by one zone view, other zone
   views would return an error about missing key files. This has been
   fixed. :gl:`#5315`
 
-- Use IPv6 queries in delv +ns.
-
-  `delv +ns` invokes the same code to perform name resolution as
-  `named`, but it neglected to set up an IPv6 dispatch object first.
-  Consequently, it was behaving more like `named -4`. It now sets up
-  dispatch objects for both address families, and performs resolver
-  queries to both v4 and v6 addresses, except when one of the address
-  families has been suppressed by using `delv -4` or `delv -6`.
