Changes from release announce:

Security Fixes

*  Windows binary packages distributed by ISC are now built and linked
   against OpenSSL 1.0.0i

New Features

*  None

Feature Changes

*  BIND now recognizes the TLSA resource record type, created to
   support IETF DANE (DNS-based Authentication of Named Entities)
   [RT #28989]

Bug Fixes

*  The locking strategy around the handling of iterative queries
   has been tuned to reduce unnecessary contention in a multi-threaded
   environment.  (Note that this may not provide a measurable
   improvement over previous versions of BIND, but it corrects the
   performance impact of change 3309 / RT #27995) [RT #29239]

*  Addresses a race condition that can cause named to to crash when
   the masters list for a zone is updated via rndc reload/reconfig
   [RT #26732]

*  named-checkconf now correctly validates dns64 clients acl
   definitions. [RT #27631]

*  Fixes a race condition in zone.c that can cause named to crash
   during the processing of rndc delzone [RT #29028]

*  Prevents a named segfault from resolver.c due to procedure
   fctx_finddone() not being thread-safe.  [RT #27995]

*  Improves DNS64 reverse zone performance. [RT #28563]

*  Adds wire format lookup method to sdb. [RT #28563]

*  Uses hmctx, not mctx when freeing rbtdb->heaps to avoid triggering
   an assertion when flushing cache data. [RT #28571]

*  Resolves inconsistencies in locating DNSSEC keys where zone names
   contain characters that require special mappings [RT #28600]

*  A new flag -R  has been added to queryperf for running tests
   using non-recursive queries.  It also now builds correctly on
   MacOS version 10.7 (darwin)  [RT #28565]

*  Named no longer crashes if gssapi is enabled in named.conf but
   was not compiled into the binary [RT #28338]

*  SDB now handles unexpected errors from back-end database drivers
   gracefully instead of exiting on an assert. [RT #28534]
