[Pdns-announce] First Alpha Release of PowerDNS Recursor 4.8.0

[Otto Moerbeek]

Hello!

   We are proud to announce the first alpha 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.
     * Optional [2]Serve Stale functionality has been implemented,
       providing resilience against connectivity problems towards
       authoritative servers.
     * Optional [3]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 [4]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.

   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 final 4.8 release, the 4.5.x releases will be EOL and the
   4.6.x and 4.7.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 also like to announce the upcoming removal of [14]XPF support. If
   you are using this feature, plan switching to the [15]proxy protocol.

   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.
