We released PowerDNS DNSdist 1.8.4 today, fixing a race condition in the handling of incoming DNS over TLS connections that can lead to a crash.
We also fixed two minor incompatibility issues preventing DNSdist from being built with newer versions of clang and the Boost library.
Please see the DNSdist website for the changelog and the current documentation.
Please send us all feedback and issues you might have via the mailing list, or in case of a bug, via GitHub.
The release tarball and its signature are available on the downloads website, and packages for several distributions are available from our repository.
