   We are proud to announce the release of PowerDNS Recursor 4.8.0.

   Compared to the previous major (4.7) release of PowerDNS Recursor, this
   release contains the following major changes:

     * [1]Structured Logging has been implemented for almost all
       subsystems. This allows for improved (automated) analysis of
       logging information. We've posted a [2]blog about this feature
     * Optional [3]Serve Stale functionality has been implemented,
       providing resilience against connectivity problems towards
       authoritative servers.
     * Optional [4]Record Locking has been implemented, providing an extra
       layer of protection against spoofing attempts at the price of
       reduced cache efficiency.
     * Internal tables used to track information about authoritative
       servers are now [5]shared instead of per-thread, resulting in
       better performance and lower memory usage.
     * EDNS padding of outgoing DoT queries has been implemented,
       providing better privacy protection.
     * Metrics have been added about the protobuf and dnstap logging
       [6]subsystems and the [7]rcodes received from authoritative

   As always, there are also many smaller bug fixes and improvements,
   please refer to the [8]changelog for additional details. When upgrading
   do not forget to check the [9]upgrade guide.

   We are also announcing the removal of [10]XPF support. If you are using
   this feature, switch to the [11]Proxy Protocol.

   Please send us all feedback and issues you might have via
   the [12]mailing list, or in case of a bug, via [13]GitHub.

   The [14]tarball ([15]signature) is available from our download
   [16]server and packages for several distributions are available from
   our [17]repository.

   With the 4.8.0 release, the 4.5.x releases will be marked "End of Life"
   and the 4.6.x and 4.7.x releases will go into critical fixes only mode.
   Consult the EOL [18]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

   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.
