[Pdns-announce] Release of PowerDNS Recursor 5.1.0

[Otto Moerbeek]

Release of PowerDNS Recursor 5.1.0

   We are proud to announce the release of PowerDNS Recursor 5.1.0!

   Compared to the latest 5.0 release, this release adds the possibility
   to include settings previously set in the Lua configuration file in the
   YAML configuration format that was introduced in the previous release.
   See YAML settings[1] for details on the settings and the conversion of
   existing Lua configuration to the new YAML syntax. The existing Lua
   syntax is still supported.

   This release also includes the following changes:

     * The recursor.conf configuration file may contain YAML configuration
       syntax and new installs using our packages from repo.powerdns.com
       will install a configuration using YAML syntax. Note to third-party
       package maintainers: please start doing the same.
     * A feature to allow names (resolved by the system resolver[2]) in
       addition to IP addresses in the forwarding configuration . This is
       very useful in setups where where the forwarding target addresses
       are dynamic in nature.
     * Measures to handle slow authoritative servers have been improved.
       Under load, the Recursor will gradually reduce the time it is
       willing to wait for answers from authoritative servers.
     * A structured logging backend[3] that uses JSON representation has
       been added.
     * Notifies can now be used to trigger[4] RPZ freshness checks.
     * The Newly Observed Domain (and/or Unique Domain Response) database
       is now shared between threads, avoiding multiple copies in memory
       and on disk. It is now also possible to set the snapshot
       interval[5].
     * Structured logging is now enabled[6] always, it is no longer
       possible to switch to old style logging.
     * arm64 packages are being published for specific distributions.

   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.
