PowerDNS Authoritative Server 4.0.4 released!

Jun 23, 2017

Today we are releasing version 4.0.4 of the PowerDNS Authoritative Server.

This release features a fix for the ed25519 signer. This signer hashed the message before signing, resulting in unverifiable signatures. Also on the Elliptic Curve front, support was added for ED448 (DNSSEC algorithm 16) by using libdecaf.

The full changelog is as follows:

  • #4911: Fix negative port detection for IPv6 addresses on 32-bit

  • #5297: Create additional reuseport sockets before dropping privileges; remove transaction in pgpsql backend
