Hello!
We are proud to announce the first beta release of what should become PowerDNS Recursor 4.3.0.
Compared to the third alpha release, this release enables QName-Minimization by default and introduces a less strict version of RFC 8020 “NXDOMAIN: There Really Is Nothing Underneath” functionality. This solves some failures to resolve specific names (as seen in the third alpha release) that are strictly speaking invalid .
Some bugs were fixed, in particular, a very slow creeping memory leak is plugged and a bug in the maintenance of the cached root zone information is fixed. As always, internal improvements to data structures and code are included as well.
Please refer to the changelog for details.
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.
Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.
