PowerDNS Authoritative Server 4.0.0
===================================
- Moved to C++ 2011, a cleaner more powerful version of C++ that has
allowed us to improve the quality of implementation in many places.
- Implemented dedicated infrastructure for dealing with DNS names that
is fully "DNS Native" and needs less escaping and unescaping.
- Due to this, the PowerDNS Authoritative Server can now serve
DNSSEC-enabled root-zones.
- All backends derived from the Generic SQL backend use prepared
statements.
- Both the server and pdns_control do the right thing when chroot'ed.
- Caches are now fully canonically ordered, which means entries can be
wiped on suffix in all places
- A revived and supported ODBC backend (godbc).
- A revived and supported LDAP backend (ldap).
- Support for CDS/CDNSKEY and RFC 7344 key-rollovers.
- Support for the ALIAS record.
- The webserver and API are no longer experimental.
- The API-path has moved to /api/v1
- DNSUpdate is no longer experimental.
- ECDSA (algorithm 13 and 14) supported without in-tree cryptographic
libraries (provided by OpenSSL).
- Experimental support for ed25519 DNSSEC signatures (when compiled with
libsodium support).
- Many new pdnsutil commands.
- GeoIP backend has gained many features, and can now e.g. run based on
explicit netmasks not present in the GeoIP databases
- Removed support for LMDB.
- Removed the Geo backened (use the improved GeoIP instead).
- pdnssec has been renamed to pdnsutil.
- Support for the PolarSSL/MbedTLS, Crypto++ and Botan cryptographic
libraries have been dropped in favor of the (faster) OpenSSL libcrypto
(except for GOST, which is still provided by Botan).
- ECDSA P256 SHA256 (algorithm 13) is now the default algorithm when
securing zones.
- The PowerDNS Authoritative Server now listens by default on all IPv6
addresses.
- Several superfluous queries have been dropped from the Generic SQL
backends.
- The INCEPTION, INCEPTION-WEEK and EPOCH SOA-EDIT metadata values are
marked as deprecated and will be removed in 4.1.0
PowerDNS Authoritative Server 3.4.9
===================================
This is a minor bugfix and performance release. Two contributions
by Kees Monshouwer make 3.4.9 fully compatible with the new single
key ECDSA default that is coming in version 4.0.0.
Changes since 3.4.8:
- use OpenSSL for ECDSA signing where available (Kees Monshouwer)

3.4.8 have been built against Botan 1.10.11 instead of Botan
1.10.3 like previous packages. Please see the Botan Security page
for more information on the fixes in Botan 1.10.11. As a PowerDNS
user, these issues only affect you if you ran our -static packages
and allowed your users to upload private keys to your
configuration.

pkgsrc changes:
- SQLite 2.x support no longer exists
- SQLite 3.x support cannot be compiled outside the main package because
of how symbols are distributed, so making it a compile time option
for net/powerdns now.
Too many changes since 2.9.22.5 (over 2 years ago), see the full changelog:
http://doc.powerdns.com/md/changelog/
Upgrade notes:
- PowerDNS 3.4 comes with a mandatory database schema upgrade coming from
any previous 3.x release.
- PowerDNS 3.1 introduces native SQLite3 support for storing key material for
DNSSEC in the bindbackend. With this change, support for bind+gsql-setups
('hybrid mode') has been dropped.
- PowerDNS 3.0 introduces full DNSSEC support which requires changes
to database schemas. By default, old non-DNSSEC schema is assumed.
Please see the docs on upgrading for particular steps that need to be taken:
http://doc.powerdns.com/md/authoritative/upgrading/
The PowerDNS nameserver is a modern, advanced and high performance
authoritative-only nameserver. It is written from scratch and conforms
to all the relevant DNS standards documents. PowerDNS is open source.
The PowerDNS nameserver utilizes a flexible backend architecture that
can access DNS information from any data source. This includes file
formats, Bind zone files, relational databases or LDAP directories.
See the net/powerdns-* packages for additional backend modules.
