First release candidate for dnsdist 1.6.0

Hi everyone,

We are happy to announce the first release candidate of what should become dnsdist 1.6.0. This release contains very few changes since the third alpha:

• Add missing getEDNSOptions and getDO bindings for DNSResponse
• Fix some issues reported by Thread Sanitizer
• Lua: don’t destroy keys during table iteration
• Disable PMTU for IPv6 as well
• Replace pthread_rwlock with std::shared_mutex

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.

We are grateful to the PowerDNS community for the reporting of bugs, issues, feature requests, and especially to the submitters of fixes and implementations of features.

Release tarballs are available on the downloads website, and packages for CentOS 7 and 8, Debian Buster and Ubuntu Bionic and Focal are available from our repository.

With the future 1.6.0 final release, the 1.3.x releases will be EOL and the 1.4.x releases will go into critical security fixes only mode.

We would also like to take this opportunity to announce that we will stop supporting systems using 32-bit time. This includes 32-bit Linux platforms like arm and i386 before kernel version 5.1.
