PowerDNS Recursor 4.1.12 Released

This is a maintenance release with improvements for high-performance sites (and a wild bug fix appeared).

The changelog:

  • #7634: Use a bounded load-balancing algo to distribute queries.
  • #7651: Implement a configurable ECS cache limit so responses with an ECS scope more specific than a certain threshold and a TTL smaller than a specific threshold are not inserted into the records cache at all.
  • #7647: Provide CPU usage statistics per thread (worker & distributor).
  • #7495: Correctly interpret an empty AXFR response to an IXFR query.

The tarball (signature) is available at downloads.powerdns.com and packages for CentOS 6 and 7, Debian Jessie and Stretch, Ubuntu Trusty, 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.
