[Pdns-announce] First beta release of PowerDNS Recursor 5.0.0

[Otto Moerbeek]

   Hello!

   We are proud to announce the first beta release of PowerDNS Recursor
   5.0.0.

   Compared the the latest 4.9 release, this pre-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 [1]documentation are automatically kept in
   sync.

   Current old-style settings are still supported without change. There is
   a semi-automatic [2]process 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. We
   encourage third-party package maintainers to take this alpha release
   and adapt their builds and provide feedback on this conversion. Our own
   package builds for various distributions are already adapted.

   We invite everybody to test this beta release. Some suggestions of
   things to test:

     * Reading an existing old-style configuration works as expected
     * Converting existing settings file(s) to YAML using the conversion
       guide
     * Running a converted or newly created YAML configuration
     * (Automatic) conversion of configuration files managed by the
       Recursor through its REST API

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

     * The recursor now has dedicated [3]thread(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 [4]extended errors in responses by
       default

   As always, there are also many smaller bug fixes and improvements,
   please refer to the [5]changelog for additional details. When upgrading
   do not forget to check the [6]upgrade guide.

   Please send us all feedback and issues you might have via
   the [7]mailing list, or in case of a bug, via [8]GitHub.

   The [9]tarball ([10]signature) is available from our
   download [11]server and packages for several distributions are
   available from our [12]repository.

   With the upcoming final 5.0.0 release, the 4.7.x releases will be EOL
   and the 4.8.x and 4.9.x releases will go into critical fixes only mode.
   Consult the EOL [13]policy 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.
