Dear Knot Resolver users,
Knot Resolver 6.0.9 (early-access) has been released!
Improvements:
- rate-limiting: add these options, mechanism, docs (!1624)
- manager: secret for TLS session resumption via ticket (RFC5077) (!1567)
The manager creates and sets the secret for all running 'kresd' workers.
The secret is created automatically if the user does not configure
their own secret in the configuration.
This means that the workers will be able to resume each other's TLS
sessions, regardless of whether the user has configured it to do so.
- answer NOTIMPL for meta-types and non-IN RR classes (!1589)
- views: improve interaction with old-style policies (!1576)
- stats: add stale answer counter 'answer.stale' (!1591)
- extended_errors: answer with EDE in more cases (!1585, !1588, !1590,
!1592)
- local-data: make DNAMEs work, i.e. generate CNAMEs (!1609)
- daemon: use connected UDP sockets by default (#326, !1618)
- docker: multiplatform builds (#922, !1623)
- docker: shared VOLUMEs are prepared for configuration and cache
(!1625, !1627)
Configuration path was changed to standard
'/etc/knot-resolver/config.yaml'.
Bugfixes:
- daemon/proxyv2: fix informing the engine about TCP/TLS from the actual
client (!1578)
- forward: fix wrong pin-sha256 length; also log pins on mismatch
(!1601, #813)
Incompatible changes:
- -f/--forks is removed (#631, !1602)
- gnutls < 3.4 support is dropped, released over 9 years ago (!1601)
- libuv < 1.27 support is dropped, released over 5 years ago (!1618)

Hello.
In case you're using our 5.x upstream repositories for Debian or Ubuntu,
as originally suggested on https://www.knot-resolver.cz/download/
<https://www.knot-resolver.cz/download/> you'll be running into an
expired signing key since yesterday. As we haven't updated in time
again, manual action is needed on every machine, I'm afraid.
Let's take this as an opportunity to migrate to our newer repositories
that should work better. You may already know them e.g. from version
6.x or Knot DNS. Setup is described at
https://pkg.labs.nic.cz/doc/?project=knot-resolver
<https://pkg.labs.nic.cz/doc/?project=knot-resolver>
You may want to also uninstall the original helper package by:
apt purge knot-resolver-release
Thanks for bearing with this inconvenience.
