   Hello,

   We are proud to announce the release of PowerDNS Recursor 5.0.1! This
   is the first public release of the 5.0 branch.

   Compared to the latest 4.9 release, this release features the ability
   to read settings from YAML files, enhancing structure, processing and
   error-checking of settings.

   There is also an internal change: the code processing the YAML file is
   written in Rust and generated from a table. The former allows for more
   secure code and the latter has the big advantage that old-style
   settings, YAML settings and documentation[1] are automatically kept in
   sync.

   Current old-style settings are still supported without change. There is
   a semi-automatic process[2] to convert old setting files to the new
   format. A future release will remove support for the old-style
   settings.

   Introducing Rust code implies that the build procedure has changed. Our
   own package builds for various distributions are adapted.

   In addition to YAML settings, this pre-release  also includes the
   following changes

     * The Recursor now has dedicated thread[3](s) to process incoming TCP
       queries
     * Improvements to the handling of a few edge cases related to NS
       records
     * A few files that are generated are now packaged in the source
       tarball, so that package builds do not have to generate them
     * The Recursor now includes extended[4] errors in responses by
       default
     * By default, the Recursor now disallows queries without the
       Recursion Desired (RD) [5]bit set.
     * The default of nsec3-max-iterations[6] has been lowered to 50.

   As always, there are also many smaller bug fixes and improvements,
   please refer to the changelog[7] for additional details. When upgrading
   do not forget to check the upgrade guide.[8]

   Please send us all feedback and issues you might have via the mailing
   list[9], or in case of a bug, via GitHub[10].

   The tarball[11] (signature[12]) is available from our
   download server[13] and packages for several distributions are
   available from our repository[14].

   We also made changes to our Open Source End of Life policy. Older
   release trains are now supported for one year after the following major
   release. Consult the EOL policy[15] for more details.

   We would also like to mention that with the 4.5 release we stopped
   supporting systems using 32-bit time. This includes many 32-bit Linux
   platforms.

   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.
