This is the release of Authoritative Server 4.8.0.
In Authoritative Server 4.8, the LMDB backend gains a new Lightning
Stream-compatible schema, which requires a data migration (this is
automatic, and there is no migration back to the old schema). LMDB
backend users should pay extra attention to the Upgrade Notes.
Lightning Stream is an open source data syncer that allows
multiple nodes to sync LMDB (Lightning Memory-Mapped Database) data to
and from an S3 (compatible) bucket. This has particular advantages in
distributed and/or large-scale applications (i.e. ~1 million records),
making DNS replication much, much easier to manage.
We are excited about how Lightning Stream simplifies running multiple
distributed PowerDNS Authoritative servers, with full support for
keeping record data and DNSSEC keys in sync, from multiple writers.
4.8.0 improves on the logic for dealing with domains existing twice in the database when two Lightning Stream nodes manage to add it at the same time. It also contains a few other fixes. A full list of changes can be found in the changelog.
Please make sure to read the Upgrade Notes before upgrading.
The tarball (signature) is available
at downloads.powerdns.com. Packages for various distributions are
available from repo.powerdns.com.
Please send us all feedback and issues you might have via
the mailing list, or in case of a bug, via GitHub.
