[dnsdist] First release release of dnsdist 1.7.0

[Remi Gacogne]

Hi everyone!

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 [1] for the more complete changelog [2] 
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 [3].

The release tarball [4] and its signature [5] are available on the 
downloads website, and packages for several distributions are available 
from our repository [6].

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.

Finally, we would like to thank the PowerDNS community and all external 
contributors for their great work in this release!
