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 43~~~~~~~~~~~~ 44 45- There are no new known issues with this release. See :ref:`above 46 <relnotes_known_issues>` for a list of all known issues affecting this 47 BIND 9 branch. 48
