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.
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.
