PowerDNS Recursor 4.2.0 Beta 1 Released

May 7, 2019

The Beta 1 release comes with a lot of bug fixes, improvements and also some new features:

  • Add a new max-cache-bogus-ttl option to cap the TTL of a record that has been validated as Bogus in the query cache, so it is not kept around for days if the initial TTL is high,
  • Add options dont-throttle-names and dont-throttle-netmasks to throttle authoritative servers that do not answer queries or send responses the recursor does not like,
  • Add an option (pdns-distributes-queries) to make the distributor thread use a bounded load-balancing algorithm while distributing queries to worker threads, making sure that no thread is assigned more queries than distribution-load-factor times the average number of queries currently processed by all the workers.

Please see the changelog for details.

This release was made possible by contributions from: Aki Tuomi, Chris Hofstaedtler, Shane Kerr and Sebastian.

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