PowerDNS Recursor 4.2.1 Released

This is a maintenance release that fixes a few issues. In particular, a very slow creeping memory leak is plugged and an rare failure to resolve specific names when the dnssec configuration is set to validate has been fixed.

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.
