   We are proud to announce the second alpha release of PowerDNS Recursor
   5.5.0!

   Compared to the latest 5.4 release, this pre-release includes the
   following changes:

     * MLDSA44 (Module-Lattice Digital Signature Algorithm) is now
       supported if the OpenSSL library used provides it. See this [1]blog
       post for more details.
     * More (empty) [2]Special Use domains were added, see
     * A feature was added to keep a list of names in the record cache
       [3]up-to-date, independent of use.
     * [4]Named interfaces can be used to specify source addresses.
     * RPZ updates now [5]wipe relevant entries from the packet cache by
       default.
     * Protobuf [6]logging can now use a 4 byte framing format and a
       strategy when sending to multiple remote logging targets.
     * The embedded web server can now read its TLS key and certificate
       information from an encrypted [7]PKCS12 (pfx) file.
     * Outgoing DoT connections can optionally use a client [8]certificate
       to provide authentication to an authoritative server or forward
       target.
     * Optionally an [9]EDE can be emitted if a name is covered by an NTA,
       contributed by Babak Farrokhi (Quad9).

   As always, there are also many smaller bug fixes and improvements,
   please refer to the [10]changelog for additional details. When
   upgrading do not forget to check the [11]upgrade guide.

   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.

   Older release trains are supported for one year after the following
   major release. Consult the EOL [18]policy for more details.

   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.
