For inline-signed zones, the value of "ixfr-from-differences" is
hardcoded to:
- "yes" for the raw version of the zone,
- "no" for the signed version of the zone.
In other words, any user-provided "ixfr-from-differences" setting is
effectively ignored for an inline-signed zone. Ensure the user is aware
of that by adding a note to the ARM and logging a message when an
"ixfr-from-differences" option is found at the zone level.
- added new 'validate-except' option, which configures an NTA with
expiry of 0xffffffff. NTAs with that value in the expiry field do not
expire, are are not written out when saving the NTA table and are not
dumped by rndc secroots
- the default setting for dnssec-validation is now "auto", which
activates DNSSEC validation using the IANA root key. The old behavior
can be restored by explicitly setting "dnssec-validation yes", which
"yes", which activates DNSSEC validation only if keys are explicitly
configured in named.conf.
- the ARM has been updated to describe the new behavior
- added a 1-second floor to max-stale-ttl similar to stale-answer-ttl;
if set to 0, it will be silently updated to 1.
- fixed the ARM entry on max-stale-ttl, which incorrectly suggested that
the default was 0 instead of 1 week.
- clarified rndc serve-stale documentation.
- mark the 'geoip-use-ecs' option obsolete; warn when it is used
in named.conf
- prohibit 'ecs' ACL tags in named.conf; note that this is a fatal error
since simply ignoring the tags could make ACLs behave unpredictably
- re-simplify the radix and iptable code
- clean up dns_acl_match(), dns_aclelement_match(), dns_acl_allowed()
and dns_geoip_match() so they no longer take ecs options
- remove the ECS-specific unit and system test cases
- remove references to ECS from the ARM
- tidy up release notes, removing the existing "security fixes" and
"bug fixes" sections
- add a section in the release notes to discuss the new version
numbering
- update version, CHANGES, api, and mapapi files
