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.
Please see the changelog for details about other improvements and bug fixes and the documentation for more details about setting up the recursor.
We want to thank everyone that contributed to this and earlier releases, and invite you to contribute to the testing of this alpha release!
The tarball (signature) is available at downloads.powerdns.com and packages for CentOS 6, 7 and 8, Debian Stretch and Buster and Ubuntu Xenial and Bionic 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.
