We are proud to announce the first, and hopefully last, release candidate of what should become PowerDNS Authoritative 4.3.0. So far this is mostly a maintenance release, but there are a few interesting changes. A lot of internals have been reworked, with some visible changes for users.
Due to a bug found in 4.3.0-beta2 right -after- we tagged RC1, this first release candidate, confusingly, is called RC2 in package versions.
If you read the upgrading notes for beta1, please see them again for an important change in NSEC(3) TTLs handling in beta2.
A notable new feature in 4.3 is support for hiding DNSSEC keys, which makes it possible to do algorithm rollovers. This feature was contributed by Robin Geuze of TransIP, thanks! Another interesting new feature is support for automatically publishing CDS/CDNSKEY records with a single pdns.conf setting.
Please note that 4.3.0 comes with a mandatory database schema upgrade.
Please see the changelog for an almost complete list of changes since the last 4.2.x release.
We want to thank everyone that contributed to this and earlier releases, and invite you to contribute to the testing of this beta release!
