available, and we recommend upgrading to it. Please read 
http://doc.powerdns.com/from3.2to3.3.html before you do, however!

Please see http://doc.powerdns.com/changelog.html#changelog-auth-3-3 for full
release notes and all download links.

These files also come with GPG signatures (append .sig).

Additionaly, Kees Monshouwer has kindly provided native builds for RHEL/CentOS
5 and 6 at http://www.monshouwer.eu/download/3rd_party/pdns-server/

This a stability, bugfix and conformity update to 3.2. It improves
interoperability with various validators, either through bugfixes or by
catering to their needs beyond the specifications.

Changes between RC2 and final:

  * pdnssec rectify-zone now refuses to operate on presigned zones, as
    rectification already happens during incoming transfer. Patch by Kees
    Monshouwer in commit 9bd211e.

  * We now handle zones with a mix of NSEC3 opt-out and non-opt-out ranges
    correctly during inbound and outbound AXFR. Many thanks to Kees Monshouwer.
    Code in commit 5aa7003 and commit d3e7b17.

  * More remotebackend fixes (commit 32d4f44, commit 44c2ee8, commit 1fcc7b7,
    commit 0b1a3b2, commit 9a319b1), thanks Aki Tuomi.

  * Some compiler warnings were squashed (commit ed554db), thanks Morten

  * Fix broken memory access in LOC parser (commit 4eec51b, commit bea513c),
    thanks Aki Tuomi.

  * DNSSEC: DS queries at the apex of a zone for which we are not hosting the
    parent, would wrongly get an 'unauth NOERROR'. Fixed by Kees Monshouwer in
    commit 34479a6.

Changes between RC1 and RC2:

  * Added dnstcpbench tool, by popular demand.

  * We always shipped a static tools RPM; we now have a similar Debian package.
    All packages have been cleaned up a bit, and the binary collections are now
    consistent between RPM and Deb. New: pass --enable-tools to configure to
    have the tools included in 'make all' and 'make install'.

  * commit 4d2e3f5: add selinux policy files

  * We would sometimes send a single NULL byte, or nothing at all, instead of
    an OPT record. Fixed in commit bf7f822, commit 063076b, commit 90d361d.

  * commit 2ee9ba2: expand any-to-tcp to direct RRSIG queries

  * commit 5fff084, commit e38ef51: drop no-op flag strict-rfc-axfrs, thanks
    Jelte Jansen.

  * commit f3d8902, commit 7c0b859, commit 5eea730: Implement MINFO qtype for
    better interaction when slaving zones from NSD (that contain MINFO). Thanks
    to Jelte Jansen.

  * commit 8655a42, commit bf79c6a, commit 38c941b: SRV record can have a '.'
    as final field, from which we would dutifully strip the trailing ., leaving
    void, confusing everything. We now remove the trailing . in the right
    place, and not if we are trying to server '.'. Again thanks to Jelte & SIDN
    for catching this.

  * commit 70d5a66: improve error message in ill formed unknown record type,
    thanks Jelte Jansen for reporting.

  * commit 3640473: Built in webserver can now listen on IPv6, fixes ticket 843
    . Also silences some useless messages about timeouts.

  * commit 7db735c, commit d72166c: CHANGES BEHAVIOUR: before we launch, check
    if we can connect to the controlsocket we are about to obliterate. If it
    works, abort. Fixes ticket 841 and changes standing behaviour. There might
    be circumstances where PowerDNS now refuses to start, where it previously
    would. However, starting and making our previous instance mute wasn't good.

  * commit 9130f9e: correctly refuse out-of-zone data in bindbackend, closes
    ticket 845

  * commit 3363ef7: initialise server-id after all parsing is done, instead of
    half way through. Fixes situations where server-id was emptied explicitly.
    Reported by Wouter de Jong

  * commit cd4f253: bump boost requirement, thanks Wouter de Jong

  * commit 58cad74: Update pdns auth init script so it works on wheezy

  * commit 8714c9c: clang fixes by Aki Tuomi, thanks!

  * commit 146601d: stretch supermasters.ip for IPv6, thanks Dennis Krul

  * commit 1a5c5f9: various remotebackend improvements by Aki Tuomi

  * commit 6ab1a11: make sure systemd starts PowerDNS after relevant databases
    have been started, thanks Morten Stevens.

  * commit 606018f, commit ee5e175, commit c76f6f4: check scopeMask of answer
    packet, not of query packet!

  * commit 2b18bcf: Added warning if trailing dot is used, thanks Aki Tuomi.

  * commit 16cf913: make superfluous 'bind' NSEC3 record optional

New features and important changes since 3.2 (these changes are in RC1 and up):

  * commit 04576ee, commit b0e15c8: Implement pdnssec increase-serial, thanks
    Ruben d'Arco.

  * commit cee857b: PowerDNS now sets additional groups while dropping

  * commit 7796a3b: Merge support for include-dir directive, thanks Aki Tuomi!

  * commit d725755: make pdns-static Conflict with pdns-server, closes ticket

  * commit c0d5504: pdnssec now emits 'INSERT INTO domain ..' queries when
    running without named.conf, thanks Ruben d'Arco.

  * commit a1d6b0c: Older versions of the BIND 9 validating recursor need a
    superfluous NSEC3 record on positive wildcard responses. We now send this
    extra NSEC3. Closes ticket 814.

  * commit 07bf35d: catch a lot more errors in pdnssec and report them. Fixes
    ticket 588.

  * commit 032e390: make pdnssec exit with 1 on some error conditions, closes
    ticket 677

  * commit 4af49b8, commit 4cec6ac: add ability to create an 'active' or
    inactive key using add-zone-key and import-zone-key, plus silenced some
    debugging. Fixes ticket 707.

  * commit fae4167: Compiling against Lua 5.2 (--with-lua=lua5.2) now disables
    some code used for regression testing, instead of breaking during compile.
    This means that Lua 5.2 can be used in production.

  * commit abc8f3f, 357f6a7: Implement the new any-to-tcp option that, when
    set, always replies with a truncated response (TC=1) to ANY queries,
    forcing them to use TCP.

  * commit 496073b: Since 3.0, pdnssec secure-zone has always generated 3 keys:
    one KSK and two ZSK, with one ZSK active. For most, if not almost all,
    users, this inactive ZSK is never used. We now no longer generate this
    useless ZSK. The resulting smaller DNSKEY RRset improves interoperability
    with certain validators. Closes ticket 824.

  * commit df55450: Non-DNSSEC ANY queries no longer get sent DNSSEC records.
    This improves interoperability with some old resolvers. Patch by Kees

  * commit 04b4bf6: Merge support for not using opt-out with NSEC3. Many thanks
    to Kees Monshouwer.

  * commit 8db49a6: We now try not to NOTIFY ourselves. In convoluted cases
    involving REUSE_PORT and binding to and ::, it might be possible
    that we guess wrong, in which case you can set prevent-self-notification to

Important bug fixes:

  * commit 63e365d: don't mess up encoding when copying qname from question to
    answer in packetcache. Based on reports&debugging by Jimmy Bergman
    (sigint), Daniel Norman (Loopia) and the fine people at ISC. This avoids
    most issues related to BIND 9 erroneously blacklisting PowerDNS for lack of
    EDNS support.

  * commit 3526186: fix backslash handling in TXT parser, includes test. Thanks
    Jan-Piet Mens.

  * commit 830281f, aef7330: Accept chars >127 ('high ASCII') in TXT records,
    closing ticket 541 and 723.

  * commit feef1ec: fix missing NSEC3 for secure delegation, thanks Kees
    Monshouwer, closes ticket 682

  * commit b61e407: around Thursday midnight, during signature rollovers, we
    would update the SOA serial too early. Fixed by reverting commit d90efbf,
    adding 7 days margin to inception. Fix by Kees Monshouwer.

  * commit ff64750: make sure mixed-case queries get a correct apex NSEC3 type

  * commit 4b153d8: always lowercase next name in NSEC to avoid interop
    troubles with validators, thanks Marco Davids&Matthijs Mekking.

Other changes:

  * commit 49977c6: fix bug in boost.m4 where it insists on setting -L, causing
    useless RPATH in our binaries. Closes ticket 728

  * commit 62ac758: use PolarSSL for MD5 hashing instead of shipping our own
    copy of md5 hashing code, thanks Aki Tuomi.

  * commit 775acd9: give a better error on trying to add nsec3 parameters to a
    weird zone like "1 0 1 ab" (which indicates that you forgot to specify a
    zone name on the command line). Fixes ticket 800.

  * commit 315dd2e: Simplify socket listening code, and make sure we always set
    the nonblocking flag correctly. Patch by Mark Zealey, closes ticket 664.

  * commit b35da1b: if_ether.h is in netinet/ not net/ on OpenBSD, thanks
    Florian Obser.

  * commit 71301b6: Replicate gsql backend feature of having separate -auth
