PowerDNS Recursor 5.0.0-alpha1 Released

Sep 13, 2023

We are proud to announce the first alpha release of PowerDNS Recursor 5.0.0.

This pre-release features the ability to read settings from YAML files, enhancing structure, processing and error-checking of settings.

There is also an internal change: the code processing the YAML file is written in Rust and generated from a table. The former allows for more secure code and the latter has the big advantage that old-style settings, YAML settings and documentation are automatically kept in sync.

Current old-style settings are still supported without change. There is a semi-automatic process to convert old setting files to the new format. A future release will remove support for the old-style settings.

Introducing Rust code implies that the build procedure has changed. We encourage third-party package maintainers to take this alpha release and adapt their builds and provide feedback on this conversion. Our own package builds for various distributions are already adapted.

We invite everybody to test this alpha release. Some suggestions of things to test:

  • Reading an existing old-style configuration works as expected
  • Converting existing settings file(s) to YAML using the conversion guide
  • Running a converted or newly created YAML configuration

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.

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 upcoming final 5.0.0 release, the 4.7.x releases will be EOL and the 4.8.x and 4.9.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.
