We’re proud to announce the third alpha release for the PowerDNS Recursor 4.3 release train. Note that a second alpha was tagged, but never released due to an issue found. A few major features are introduced:
- The recursor now processes a number of requests incoming over a TCP connection simultaneously and will return results (potentially) out-of-order.
- RFC 8020 “NXDOMAIN: There Really Is Nothing Underneath” has been implemented and is enabled by default.
- Newly Observed Domain (NOD) functionality is built and available by default.
- dnstap support for outgoing queries to authoritative servers and the corresponding replies is built and available by default.
We want to thank everyone that contributed to this and earlier releases, and invite you to contribute to the testing of this alpha release!
