Hello!
We are proud to announce the release of PowerDNS Recursor 4.3.0.
Compared to the last release candidate, only two very minor issues were fixed.
Compared to the 4.2 release of PowerDNS Recursor, the most important features that were added are:
- A relaxed form of QName Minimization as described in rfc7816bis-01. This feature is enabled by default. See the documentation for more details.
- Dnstap support for outgoing queries to authoritative servers and the corresponding replies. See the documentation for more details.
- The recursor now processes a number of requests incoming over a TCP connection simultaneously and will return results (potentially) out-of-order. See the documentation for more details on how to tune this feature.
- Newly Observed Domain (NOD) functionality. See the documentation for information on how to make use of this feature.
- When the recursor is started by
systemd, the recursor will no longer run as therootuser. Instead, it will start as thepdns-recursoruser. Make sure directories and files needed by your specific recursor setup are readable by this user. For non-systemd and non-chroot cases, the default directory for the control socket and pid file has changed to/var/run/pdns-recursor. The upgrade guide contains more information.
As usual, there were also many other smaller enhancements and bugfixes. Please refer to the changelog for details.
We want to thank everyone that contributed to the testing of the release candidates.
The tarball (signature) is available at downloads.powerdns.com and packages for CentOS 6, 7 and 8, Debian Stretch and Buster, Ubuntu Xenial and Bionic are available from repo.powerdns.com.
With this release, PowerDNS Recursor 4.0 will be become End-of-Life and PowerDNS Recursor 4.1 will only receive critical security updates. For details, see the our EOL statement.
Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.
