Fourth alpha release of PowerDNS DNSdist 1.9.0

Dec 14, 2023

We are thrilled to release the fourth alpha release of what will become PowerDNS DNSdist 1.9.0!

The most exciting new feature in this latest alpha is support for DNS over HTTP/3! Like DNS over QUIC for which we announced support in the previous alpha, DNS over HTTP/3 uses QUIC to provide excellent performance in challenging environments. We are again leveraging Cloudflare's Quiche for this new feature, keeping the number of DNSdist dependencies small.

We also added a few new, smaller features since alpha 3:

  • support for setting Extended DNS Error statuses
  • a cache-miss ratio dynamic block rule
  • getAddressInfo for asynchronous DNS resolution
  • a rings endpoint to the REST API
  • NetmaskGroup:addNMG to merge Netmask groups
  • an option to set the SSL proxy protocol TLV
  • Proxy Protocol v2 support to TeeAction
  • enabling incoming PROXY protocol on a per-bind basis
  •  the maximum size of entries in the packet cache is now configurable
  • raw response spoofing for ANY queries
  • QNameSuffixRule, PayloadSizeRule and TCResponseAction
  • DynBlockRulesGroup:removeRange
  • setting the action from setSuffixMatchRule's visitor is now supported
  •  we now send a HTTP 400 response to legacy HTTP/1.1 clients with nghttp2

We also fixed a few issues:

  • Kees Monshouwer removed legacy terms from the codebase
  • building without DoH but with nghttp2 was broken
  • Quiche detection did not properly check the version
  • DNS over QUIC latency metrics were missing
  • removing the last rule by its name or UUID was broken
  • building with DNS over QUIC but without DNS over HTTPS or DNS over TLS was broken

Please see the DNSdist website for the more complete 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.

We are grateful to the PowerDNS community for the reporting of bugs, issues, feature requests, and especially to the submitters of fixes and implementations of features.

The release tarball and its signature are available on the downloads website, and packages for several distributions are available from our repository.
