Update to 4.3.0: 

  A lot of internals have been reworked, with some visible changes
  for users. If you read the upgrade notes for a beta or RC, please
  read them again!

  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.
