PowerDNS Recursor 5.1.3 Released

Today we have released PowerDNS Recursor 5.1.3.

This release is a maintenance releases that fixes a few bugs and has a few improvements. The most important ones are:

• RFC 6303 has been implemented, letting the recursor provide answers to some ipv6.arpa zones. This function is switched on by default.
• An issue where a burst of many identical queries on a non-cache hit could lead to intermittent failure to resolve has been fixed.
• The metrics now distinguish OS imposed limits from application imposed limits. Reaching the maximum chain size is now reported using the new chain-limits metric, while previously they would increase the resource-limits metric.

There are also a few other bug fixes and improvements, please refer to the changelog  (5.1.3) for additional details.

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

The tarball (5.1.3) (with signature file 5.1.3) are available from our download server and packages for several distributions are available from our repository.

Recently we made changes to our Open Source End of Life policy. Older release trains are now supported for one year after the following major release. 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.
