[dnsdist] Second beta release of dnsdist 1.7.0

[Remi Gacogne]

Hi everyone!

We are happy to announce the second beta release of dnsdist 1.7.0, with 
few fixes since the first beta, the most important one being a memory 
leak when reusing TLS sessions for outgoing DNS over TLS and DNS over 
HTTPS connections. During that work we stumbled upon a memory leak in 
some setups using GnuTLS which will have to be fixed in the library 
itself. After reporting it upstream we added a warning in dnsdist which 
will be removed when a fixed version of GnuTLS has been released.

We also fixed an error in the way we check for integer overflows in 
configuration values, which could have refused valid configurations.

Finally we added a function to see the current configuration of the 
internal web server.

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!
