New Features
* Zones may be dynamically added and removed with the "rndc addzone"
and "rndc delzone" commands. These dynamically added zones are
written to a per-view configuration file. Do not rely on the
configuration file name nor contents as this will change in a
future release. This is an experimental feature at this time.
* Added new "filter-aaaa-on-v4" access control list to select which
IPv4 clients have AAAA record filtering applied.
* A new command "rndc secroots" was added to dump a combined summary
of the currently managed keys combined with statically configured
trust anchors.
* Added support to load new keys into managed zones without signing
immediately with "rndc loadkeys". Added support to link keys with
"dnssec-keygen -S" and "dnssec-settime -S".
Changes
* Documentation improvements
* ORCHID prefixes were removed from the automatic empty zone list.
* Improved handling of GSSAPI security contexts. Specifically, better
memory management of cached contexts, limited lifetime of a context
to 1 hour, and added a "realm" command to nsupdate to allow
selection of a non-default realm name.
* The contributed tool "ztk" was updated to version 1.0.
Security Fixes
* If BIND, acting as a DNSSEC validating server, has two or more
trust anchors configured in named.conf for the same zone (such as
example.com) and the response for a record in that zone from the
authoritative server includes a bad signature, the validating
server will crash while trying to validate that query.
* A flaw where the wrong ACL was applied was fixed. This flaw allowed
access to a cache via recursion even though the ACL disallowed it.
Bug Fixes
* Removed a warning message when running BIND 9 under Windows for
when a TCP connection was aborted. This is a common occurrence and
the warning was extraneous.
* Worked around a race condition in the cache database memory
handling. Without this fix a DNS cache DB or ADB could incorrectly
stay in an over memory state, effectively refusing further caching,
which subsequently made a BIND 9 caching server unworkable.
* Partially disabled change 2864 because it would cause infinite
attempts of RRSIG queries.
* BIND did not properly handle non-cacheable negative responses from
insecure zones. This caused several non-protocol-compliant zones to
become unresolvable. BIND is now more accepting of responses it
receives from less strict servers.
* A bug, introduced in BIND 9.7.2, caused named to fail to start if a
master zone file was unreadable or missing. This has been corrected
in 9.7.2-P1.
* BIND previously accepted answers from authoritative servers that
did not provide a "proper" response, such as not setting AA bit.
BIND was changed to be more strict in what it accepted but this
caused operational issues. This new strictness has been backed out
in 9.7.2-P1.
* meta: Ensure that the url specified by xrds-location is absolute.
* attachment: Fix attachment file size display.
* Propigate PATH into wrapper.
* htmlbalance: Fix compatibility with HTML::Tree 4.0. (smcv)
Updating during the freeze for bugfixes to a leaf package.
