involved extensive restructuring of the reference counting of
zones and related objects.
Zones now attach to their views. To avoid a circular dependency that
would keep views from ever shutting down, this is done using the new
functions dns_view_weakattach() / dns_view_weakdetach() which
guarantee that the view will not be freed but still allow it
to be shut down.
The zones themselves now only have a single reference count, with
similar "weak" semantics. Managed zones must now be shut down
explicitly by calling dns_zone_shutdown(). To shut down all
zones in a zone table, call dns_zt_shutdown().
The zone manager is now reference counted, weakly. To shut down the
zone manager, you must explicitly call dns_zonemgr_shutdown().
statements.
- Post-load of named.conf check verifies a slave zone has non-empty list
of masters defined.
- New per-zone boolean:
enable-zone yes | no ;
- intended to let a zone be disabled without having to comment out the
entire zone statement.
- New global and per-view option:
max-cache-ttl number
- New global and per-view option:
addition-data internal | minimal | maximal;

command a bit more obvious.
Addition of TCP fallback on UDP failure. Will add option to disable this.
Further work on nslookup.
(nslookup is not built by default now, and is far from fully functional.
Interactive mode currently segfaults.)
allow-query ACL, subsequent accesses to the same zone were denied because
dbversion->queryok was not being set. This caused mandatory glue to be
omitted from referral responses, ultimately causing lookups to fail if all
authoritative servers for the parent zone were running bind9.
