First release candidate of dnsdist 1.7.0

Hello!

We are happy to announce the first release candidate of what will become dnsdist 1.7.0, with only one fix and one improvement since the second beta.

We fixed a crash introduced in 1.7.0-alpha1 that could occur when a DoH query was forwarded to a backend over TCP, DoT or DoH and the response was dropped by a rule.

We also improved the health-checks queries done over DoT so that we could use any cached TLS ticket when connecting to the server, but also save new tickets so that they can be used for later connections. That reduces the CPU load and improves response time on devices dealing with a low number of queries per second.

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.

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

With the future 1.7.0 final release, the 1.4.x releases will be EOL and the 1.5.x and 1.6.x releases will go into critical security fixes only mode.
