Security Fixes

   Treat an all zero netmask as invalid when generating the localnets
   acl to work around a bug on the Windows platform.[CVE-2013-6230]
   [RT #34687]

   Fix crashes when serving some NSEC3 signed zones.  memcpy was
   incorrectly called with overlapping ranges, resulting in malformed
   names being generated on some platforms. This could cause INSIST
   failures. (CVE 2014-0591) [RT #35120] **

Feature Changes

   Add the ability to specify ndots to "nslookup". [RT #34711]

   Check that EDNS subnet client options are well formed. [RT #34718]

   "named" now preserves the capitalization of names when responding
   to queries. [RT #34737]

   Use separate rate limiting queues for refresh and notify requests.
   [RT #30589]

   Adjust when a master server is deemed unreachable to be less
   aggressive. [RT #27075]

   Create delegations for all "children" of empty zones except
   "forward first". [RT #34826]

   Include a comment in .nzf files (used for adding new zones via
   "rndc"), giving the name of the associated view. [RT #34765]

   Changed the name of "isc-config.sh" developers script (for
   outputting compiler and linker flags) to "bind9-config". [RT #23825]

   Add "dig" option to keep the TCP socket open between successive
   queries (+[no]keepopen).  [RT #34918]

   "named-checkconf -z" now checks zones of type hint as well as
   master. [RT #35046]

   Update config.guess and config.sub to add support for ppc64le
   (powerpc 64-bit Little Endian). [RT #35060]

   Update the Windows build system to support feature selection and
   WIN64 builds. This is a work in progress. [RT #34160]

   Add a more detailed "not found" message to "rndc" commands which
   specify a zone name. [RT #35059]

   named will now warn when a zone's configured "key-directory"
   does not exist or is not a directory. [RT #35108] **

   "named-checkconf" can now obscure shared secrets when printing
   by specifying '-x'. [RT #34465] **

Bug Fixes

   Treat type 65533 (KEYDATA) as opaque except when used in a key
   zone. [RT #34238]

   Fix "host" and "nslookup" so don't need dot after the domain by
   checking ndots when searching. Only continue searching on NXDOMAIN
   responses. [RT #34711]

   Handle changes to sig-validity-interval settings better. [RT
   #34625]

   Fix bug where journal filename string could be set incorrectly,
   causing garbage in log messages. [RT #34738]

   #34838]

   Fix "host" failure if a UDP query timed out. [RT #34870]

   Address bugs in dns_rdata_fromstruct and dns_rdata_tostruct for
   WKS and ISDN types. [RT #34910]

   Updated OpenSSL PKCS#11 patches to fix active list locking and
   other bugs. [RT #34855]

   Fix cast in lex.c which could see 0xff treated as EOF. This fixes
   issue with potential bad data in a database used by DLZ or SDB.
   [RT #34993]

   Fix build issue on newer FreeBSD needing -lhx509 for GSSAPI
   build. [RT #35001]

   zone to another to fail with a broken trust chain. [RT #35081]
   **

   were fatal if there was no data at the node. [RT #35080] **

   Fix a possible race and crash in the socket_search() function
   in dispatch.c. [RT #35107] **
