* --enable-gost : use the GOST algorithm (experimental).
* Added some missing options to drill manpage
* Some fixes to --without-ssl option
* Fixed quote parsing withing strings
* Bitmask fix in EDNS handling
* Fixed non-fqdn domain name completion for rdata field domain
names of length 1

1.6.0
Additions:
* Addition of an ldns-config script which gives cflags and libs
values, for use in configure scripts for applications that use
use ldns. Can be disabled with ./configure --disable-ldns-config
* Added direct sha1, sha256, and sha512 support in ldns.
With these functions, all NSEC3 functionality can still be
used, even if ldns is built without OpenSSL. Thanks to OpenBSD,
Steve Reid, and Aaron D. Gifford for the code.
* Added reading/writing support for the SPF Resource Record
* Base32 functions are now exported
Bugfixes:
* ldns_is_rrset did not go through the complete rrset, but
only compared the first two records. Thanks to Olafur
Gudmundsson for report and patch
* Fixed a small memory bug in ldns_rr_list_subtype_by_rdf(),
thanks to Marius Rieder for finding an patching this.
* --without-ssl should now work. Make sure that examples/ and
drill also get the --without-ssl flag on their configure, if
this is used.
* Some malloc() return value checks have been added
* NSEC3 creation has been improved wrt to empty nonterminals,
and opt-out.
* Fixed a bug in the parser when reading large NSEC3 salt
values.
* Made the allowed length for domain names on wire
and presentation format the same.
Example tools:
* ldns-key2ds can now also generate DS records for keys without
the SEP flag
* ldns-signzone now equalizes the TTL of the DNSKEY RRset (to
the first non-default DNSKEY TTL value it sees)
1.5.1
Example tools:
* ldns-signzone was broken in 1.5.0 for multiple keys, this
has been repaired
Build system:
* Removed a small erroneous output warning in
examples/configure and drill/configure
1.5.0
Bug fixes:
* fixed a possible memory overflow in the RR parser
* build flag fix for Sun Studio
* fixed a building race condition in the copying of header
files
* EDNS0 extended rcode; the correct assembled code number
is now printed (still in the EDNS0 field, though)
* ldns_pkt_rr no longer leaks memory (in fact, it no longer
copies anything all)
API addition:
* ldns_key now has support for 'external' data, in which
case the OpenSSL EVP structures are not used;
ldns_key_set_external_key() and ldns_key_external_key()
* added ldns_key_get_file_base_name() which creates a
'default' filename base string for key storage, of the
form "K<zone>+<algorithm>+<keytag>"
* the ldns_dnssec_* family of structures now have deep_free()
functions, which also free the ldns_rr's contained in them
* there is now an ldns_match_wildcard() function, which checks
whether a domain name matches a wildcard name
* ldns_sign_public has been split up; this resulted in the
addition of ldns_create_empty_rrsig() and
ldns_sign_public_buffer()
Examples:
* ldns-signzone can now automatically add DNSKEY records when
using an OpenSSL engine, as it already did when using key
files
* added new example tool: ldns-nsec3-hash
* ldns-dpa can now filter on specific query name and types
* ldnsd has fixes for the zone name, a fix for the return
value of recvfrom(), and an memory initialization fix
(Thanks to Colm MacCárthaigh for the patch)
* Fixed memory leaks in ldnsd
1.4.1
Bug fixes:
* fixed a build issue where ldns lib existence was done too early
* removed unnecessary check for pcap.h
* NSEC3 optout flag now correctly printed in string output
* inttypes.h moved to configured inclusion
* fixed NSEC3 type bitmaps for empty nonterminals and unsigned
delegations
API addition:
* for that last fix, we added a new function
ldns_dname_add_from() that can clone parts of a dname
1.4.0
Bug fixes:
* sig chase return code fix (patch from Rafael Justo, bug id 189)
* rdata.c memory leaks on error and allocation checks fixed (patch
from Shane Kerr, bug id 188)

* buffer2str() is now called ldns_buffer2str
* base32 and base64 function names are now also prepended with ldns_
* ldns_rr_new_frm_str() now returns an error on missing RDATA fields.
Since you cannot read QUESTION section RRs with this anymore,
there is now a function called ldns_rr_new_question_frm_str()
LIBRARY FEATURES:

1.3
Base library:
* Added a new family of functions based around ldns_dnssec_zone,
which is a new structure that keeps a zone sorted through an
rbtree and links signatures and NSEC(3) records directly to their
RRset. These functions all start with ldns_dnssec_
* ldns_zone_sign and ldns_zone_sign_nsec3 are now deprecated, but
have been changed to internally use the new
ldns_dnssec_zone_sign(_nsec3)
* Moved some ldns_buffer functions inline, so a clean rebuild of
applications relying on those is needed (otherwise you'll get
linker errors)
* ldns_dname_label now returns one extra (zero)
byte, so it can be seen as an fqdn.
* NSEC3 type code update for signing algorithms.
* DSA key generation of DNSKEY RRs fixed (one byte too small).
* Added support for RSA/SHA256 and RSA/SHA512, as specified in
draft-ietf-dnsext-dnssec-rsasha256-04. The typecodes are not
final, and this feature is not enabled by default. It can be
enabled at compilation time with the flag --with-sha2
* Added 2wire_canonical family of functions that lowercase dnames
in rdata fields in resource records of the types in the list in
rfc3597
* Added base32 conversion functions.
* Fixed DSA RRSIG conversion when calling OpenSSL
Drill:
* Chase output is completely different, it shows, in ascii, the
relations in the trust hierarchy.
Examples:
* Added ldns-verify-zone, that can verify the internal DNSSEC records
of a signed BIND-style zone file
* ldns-keygen now takes an -a argument specifying the algorithm,
instead of -R or -D. -a list show a list of supported algorithms
* ldns-keygen now defaults to the exponent RSA_F4 instead of RSA_3
for RSA key generation
* ldns-signzone now has support for HSMs
* ldns-signzone uses the new ldns_dnssec_ structures and functions
which improves its speed, and output; RRSIGS are now placed
directly after their RRset, NSEC(3) records directly after the
name they handle
Contrib:
* new contrib/ dir with user contributions
* added compilation script for solaris (thanks to Jakob Schlyter)
28 Nov 2007 1.2.2:
* Added support for HMAC-MD5 keys in generator
* Added a new example tool (written by Ondrej Sury): ldns-compare-zones
* ldns-keygen now checks key sizes for rfc conformance
* ldns-signzone outputs SSL error if present
* Fixed manpages (thanks to Ondrej Sury)
* Fixed Makefile for -j <x>
* Fixed a $ORIGIN error when reading zones
* Fixed another off-by-one error
03 Oct 2007 1.2.1:
* Fixed an offset error in rr comparison
* Fixed ldns-read-zone exit code
* Added check for availability of SHA256 hashing algorithm
* Fixed ldns-key2ds -2 argument
* Fixed $ORIGIN bug in .key files
* Output algorithms as an integer instead of their mnemonic
* Fixed a memory leak in dnssec code when SHA256 is not available
* Updated fedora .spec file
11 Apr 2007 1.2.0:
* canonicalization of rdata in DNSSEC functions now adheres to the
rr type list in rfc3597, not rfc4035, which will be updated
(see http://www.ops.ietf.org/lists/namedroppers/namedroppers.2007/msg00183.html)
* ldns-walk now support dnames with maximum label length
* ldnsd now takes an extra argument containing the address to listen on
* signing no longer signs every rrset with KSK's, but only the DNSKEY rrset
* ported to Solaris 10
* added ldns_send_buffer() function
* added ldns-testpkts fake packet server
* added ldns-notify to send NOTIFY packets
* ldns-dpa can now accurately calculate the number of matches per
second
* libtool is now used for compilation too (still gcc, but not directly)
* Bugfixes:
- TSIG signing buffer size
- resolv.conf reading (comments)
- dname comparison off by one error
- typo in keyfetchers output file name fixed (a . too much)
- fixed zone file parser when comments contain ( or )
- fixed LOC RR type
- fixed CERT RR type
Drill:
* drill prints error on failed axfr.
* drill now accepts mangled packets with -f
* old -c option (use tcp) changed to -t
* -c option to specify alternative resolv.conf file added
* feedback of signature chase improved
* chaser now stops at root when no trusted keys are found
instead of looping forever trying to find the DS for .
* Fixed bugs:
- wildcard on multiple labels signature verification
- error in -f packet writing for malformed packets
- made KSK check more resilient
7 Jul 2006: 1.1.0: ldns-team
* Added tutorials and an introduction to the documentation
* Added include/ and lib/ dirs so that you can compile against ldns
without installing ldns on your system
* Makefile updates
* Starting usage of assert throughout the library to catch illegal calls
* Solaris 9 testing was carried out. Ldns now compiles on that
platform; some gnuism were identified and fixed.
* The ldns_zone structure was stress tested. The current setup
(ie. just a list of rrs) can scale to zone file in order of
megabytes. Sorting such zone is still difficult.
* Reading multiline b64 encoded rdata works.
* OpenSSL was made optional, configure --without-ssl.
Ofcourse all dnssec/tsig related functions are disabled
* Building of examples and drill now happens with the same
defines as the building of ldns itself.
* Preliminary sha-256 support was added. Currently is your
OpenSSL supports it, it is supported in the DS creation.
* ldns_resolver_search was implemented
* Fixed a lot of bugs
Drill:
* -r was killed in favor of -o <header bit mnemonic> which
allows for a header bits setting (and maybe more in the
future)
* DNSSEC is never automaticaly set, even when you query
for DNSKEY/RRSIG or DS.
* Implement a crude RTT check, it now distinguishes between
reachable and unreachable.
* A form of secure tracing was added
* Secure Chasing has been improved
* -x does a reverse lookup for the given IP address
Examples:
* ldns-dpa was added to the examples - this is the Dns Packet
Analyzer tool.
* ldnsd - as very, very simple nameserver impl.
* ldns-zsplit - split zones for parallel signing
* ldns-zcat - cat split zones back together
* ldns-keyfetcher - Fetches DNSKEY records with a few (non-strong,
non-DNSSEC) anti-spoofing techniques.
* ldns-walk - 'Walks' a DNSSEC signed zone
* Added an all-static target to the makefile so you can use examples
without installing the library
* When building in the source tree or in a direct subdirectory of
the build dir, configure does not need --with-ldns=../ anymore
Code:
* All networking code was moved to net.c
* rdata.c: added asserts to the rdf set/get functions
* const keyword was added to pointer arguments that
aren't changed
API:
Changed:
* renamed ldns/dns.h to ldns/ldns.h
* ldns_rr_new_frm_str() is extended with an extra variable which
in common use may be NULL. This trickles through to:
o ldns_rr_new_frm_fp
o ldns_rr_new_frm_fp_l
Which also get an extra variable
Also the function has been changed to return a status message.
The compiled RR is returned in the first argument.
* ldns_zone_new_frm_fp_l() and ldns_zone_new_frm_fp() are
changed to return a status msg.
* ldns_key_new_frm_fp is changed to return ldns_status and
the actual key list in the first argument
* ldns_rdata_new_frm_fp[_l]() are changed to return a status.
the rdf is return in the first argument
* ldns_resolver_new_frm_fp: same treatment: return status and
the new resolver in the first argument
* ldns_pkt_query_new_frm_str(): same: return status and the
packet in the first arg
* tsig.h: internal used functions are now static:
ldns_digest_name and ldns_tsig_mac_new
* ldns_key_rr2ds has an extra argument to specify the hash to
use.
* ldns_pkt_rcode() is renamed to ldns_pkt_get_rcode, ldns_pkt_rcode
is now the rcode type, like ldns_pkt_opcode
New:
* ldns_resolver_searchlist_count: return the searchlist counter
* ldns_zone_sort: Sort a zone
* ldns_bgsend(): background send, returns a socket.
* ldns_pkt_empty(): check is a packet is empty
* ldns_rr_list_pop_rr_list(): pop multiple rr's from another rr_list
* ldns_rr_list_push_rr_list(): push multiple rr's to an rr_list
* ldns_rr_list_compare(): compare 2 ldns_rr_lists
