   We are proud to announce the first beta 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 final 4.8 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 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.
