First Beta Release of PowerDNS Recursor 4.8.0

Oct 5, 2022 6:00:00 AM

We are proud to announce the first beta release of PowerDNS Recursor 4.8.0.

Compared to the previous major (4.7) release of PowerDNS Recursor, this release contains the following major changes:

  • Structured Logging has been implemented for almost all subsystems. This allows for improved (automated) analysis of logging information. We’ve posted a blog about this feature recently.
  • Optional Serve Stale functionality has been implemented, providing resilience against connectivity problems towards authoritative servers.
  • Optional Record Locking has been implemented, providing an extra layer of protection against spoofing attempts at the price of reduced cache efficiency.
  • Internal tables used to track information about authoritative servers are now shared instead of per-thread, resulting in better performance and lower memory usage.
  • EDNS padding of outgoing DoT queries has been implemented, providing better privacy protection.
  • Metrics have been added about the protobuf and dnstap logging subsystems and the rcodes received from authoritative servers.

As always, there are also many smaller bug fixes and improvements, please refer to the changelog for additional details. When upgrading do not forget to check the upgrade guide.

We are also announcing the removal of XPF support. If you are using this feature, switch to the proxy protocol.

Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.

The tarball (signature) is available from our download server and packages for several distributions are available from our repository.

With the final 4.8 release, the 4.5.x releases will be marked “End of Life” and the 4.6.x and 4.7.x releases will go into critical fixes only mode. Consult the EOL policy for more details.

We would also like to mention that with the 4.5 release we stopped supporting systems using 32-bit time. This includes many 32-bit Linux platforms.

We are grateful to the PowerDNS community for the reporting of bugs, issues, feature requests, and especially to the submitters of fixes and implementations of features.
