[Pdns-announce] First release candicate of PowerDNS Recursor 5.2.0

[Otto Moerbeek]

   We are proud to announce the first release candidate of PowerDNS
   Recursor 5.2.0!

   Compared to the latest 5.1 release, this pre-release deprecates the old
   settings file format in favor of the new YAML format. Old-style
   settings are only accepted if --enable-old-settings[1] is specified on
   the command line.

   This release also includes the following changes:

     * Forward zones can now be populated using catalog zones[2].
     * The authoritative servers to transfer RPZs or catalog zones from
       can now be specified by hostname.
     * Lua functions[3] to create threads running Lua code, dump and
       restore (parts of) the record cache and to invoke Lua hooks[4] on
       startup and shutdown have been added.
     * Metrics related code for the various ways to export metrics and the
       related documentation is now generated from a single source,
       providing better maintainability and consistency.
     * The trust anchor of the new root zone key scheduled to be used for
       signing the root zone starting October 2026 has been added.
     * Infrastructure to build using Meson instead of auto-tools has been
       introduced. We plan to make the meson build the default in a future
       release.
     * The default maximum number of incoming TCP connections has been
       raised to 1024.

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

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

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

   Older release trains are supported for one year after the following
   major release. Consult the EOL policy[13] 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.
