--- features: - | Add support for providing catalog zones. Designate can now optionally provide catalog zones for pools. Defined in `RFC 9432 `_, catalog zones allow for provisioning of DNS zones on secondary nameservers through the sole means of DNS. A special zone, the catalog zone, serves as a list of all zones the secondary nameservers should serve and for which they will set themselves up automatically. The synchronization of zones via a catalog zone happens via known and proven AXFR, just like for a zone's DNS records. Provisioning via catalog zones is already supported by popular DNS implementations, such as BIND9, Knot and PowerDNS (and likely others). Apart from being a standardized provisioning model, the main advantage of catalog zones is the scalability and robustness of keeping secondary nameservers in sync.
