12Notes for BIND 9.18.18
13----------------------
14
15Feature Changes
16~~~~~~~~~~~~~~~
17
18- When a primary server for a zone responds to an SOA query, but the
19  subsequent TCP connection required to transfer the zone is refused,
20  that server is marked as temporarily unreachable. This now also
21  happens if the TCP connection attempt times out, preventing too many
22  zones from queuing up on an unreachable server and allowing the
23  refresh process to move on to the next configured primary more
24  quickly. :gl:`#4215`
25
26- The :any:`dialup` and :any:`heartbeat-interval` options have been
27  deprecated and will be removed in a future BIND 9 release. :gl:`#3700`
28
29Bug Fixes
30~~~~~~~~~
31
32- Processing already-queued queries received over TCP could cause an
33  assertion failure, when the server was reconfigured at the same time
34  or the cache was being flushed. This has been fixed. :gl:`#4200`
35
36- Setting :any:`dnssec-policy` to ``insecure`` prevented zones
37  containing resource records with a TTL value larger than 86400 seconds
38  (1 day) from being loaded. This has been fixed by ignoring the TTL
39  values in the zone and using a value of 604800 seconds (1 week) as the
40  maximum zone TTL in key rollover timing calculations. :gl:`#4032`
41
42Known Issues
