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[1].
This feature is enabled by default. See the documentation[2] for more
details.
* Dnstap support for outgoing queries to authoritative servers and the
corresponding replies. See the documentation[3] 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[4] for more details on how to tune
this feature.
* Newly Observed Domain (NOD) functionality. See the documentation[5]
for information on how to make use of this feature.
* When the recursor is started by systemd, the recursor will no longer
run as the root user. Instead, it will start as the pdns-recursor user.
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[6] contains more information.

As usual, there were also many other smaller enhancements and bugfixes.
Please refer to the changelog[7] for details.

We want to thank everyone that contributed to the testing of the release
candidates.

The tarball[8] (signature[9]) is available at downloads.powerdns.com[10]
and packages for CentOS 6, 7 and 8, Debian Stretch and Buster, Ubuntu
Xenial and Bionic are available from repo.powerdns.com[11].

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[12].

Please send us all feedback and issues you might have via the
