  <h1>GNUnet 0.13.0 released</h1>
<p>
  We are pleased to announce the release of GNUnet 0.13.0.
<br>
  This is a new major release. It breaks protocol compatibility with the 0.12.x versions.
  Please be aware that Git master is thus henceforth <b>INCOMPATIBLE</b> with
  the 0.12.x GNUnet network, and interactions between old and new peers
  will result in signature verification failures.  0.12.x peers will <b>NOT</b>
  be able to communicate with Git master or 0.13.x peers.<br/>
  In terms of usability, users should be aware that there are still
  <b>a large number of known open issues</b> in particular with respect to ease
  of use, but also some critical privacy issues especially for mobile users.
  Also, the nascent network is tiny and thus unlikely to
  provide good anonymity or extensive amounts of interesting information.
  As a result, the 0.13.0 release is still <b>only suitable for early adopters
  with some reasonable pain tolerance</b>.
</p>

<h4>Noteworthy changes in 0.13.0 (since 0.12.2)</h4>
<ul>
  <li><tt>GNS</tt>:
    <ul>
      <li>Aligned with specification <a href="https://lsd.gnunet.org/lsd0001/">LSD001</a>.
      <li>NSS plugin "block" fixed. <a href="https://bugs.gnunet.org/view.php?id=5782">#5782</a></li>
      <li>Broken set NICK API removed.<a href="https://bugs.gnunet.org/view.php?id=6092">#6092</a></li>
      <li>New record flags: SUPPLEMENTAL. Records which are not explicitly
       configured/published under a specific label but which are still
       informational are returned by the resolver and flagged accordingly. <a href="https://bugs.gnunet.org/view.php?id=6103">#6103</a></li>
      <li><tt>gnunet-namestore</tt> now complains when adding TLSA or SRV records outside of a BOX</li>
    </ul>
  </li>
  <li>
    <tt>CADET</tt>: Fixed tunnel establishment as well as an outstanding bug regarding tunnel destruction. <a href="https://bugs.gnunet.org/view.php?id=5822">#5822</a>
  </li>
  <li><tt>GNS/REVOCATION</tt>: Revocation proof of work has function changed to
  argon2 and modified to reduce variance.</li>
  <li><tt>RECLAIM</tt>: Increased ticket length to 256 bit. <a href="https://bugs.gnunet.org/view.php?id=6047">#6047</a></li>
  <li><tt>TRANSPORT</tt>: UDP plugin moved to experimental as it is known to be unstable.</li>
  <li><tt>UTIL</tt>:
    <ul>
      <li>Serialization / file format of ECDSA private keys harmonized with
      other libraries. Old private keys will no longer work! <a href="https://bugs.gnunet.org/view.php?id=6070">#6070</a></li>
      <li>Now using <a href="https://doc.libsodium.org/">libsodium</a> for EC
      cryptography.</li>
      <li>Builds against cURL which is not linked against gnutls are now possible but still not recommended.
      Configure will warn that this will impede the GNS functionality. This change will make hostlist discovery
      work more reliable for some distributions.</li>
      <li><tt>GNUNET_free_non_null</tt> removed. <tt>GNUNET_free</tt> changed to not assert that the pointer is not NULL.
      For reference see the <a href="https://taler.net/papers/codeblau-report-2020-q2.pdf">Taler security audit</a>.</li>
      <li>AGPL request handlers added GNUnet and extension templates.</li>
    </ul>
  </li>
  <li><b>(NEW) </b><tt>GANA Registry</tt>: We have established a registry to be used for names and numbers in GNUnet.
  This includes constants for protocols including GNS record types and GNUnet peer-to-peer messages. See <a href="https://gana.gnunet.org">GANA</a>.</li>
  <li><b>(NEW) </b><tt>Living Standards</tt>: LSD subdomain and LSD0001 website: <a href="https://lsd.gnunet.org/lsd0001">LSD0001</a></li>
  <li><b>(NEW) </b><tt>Continuous integration</tt>: <a href="https://buildbot.gnunet.org">Buildbot</a> is back.</li>
  <li><tt>Buildsystem</tt>: A significant number of build system changes:
    <ul>
      <li>libmicrohttpd and libjansson are now required dependencies.</li>
      <li>New dependency: <a href="https://doc.libsodium.org/">libsodium</a>.</li>
      <li>Fixed an issue with libidn(2) detection.</tt>
    </ul>
  </li>
</ul>

<h4>Known Issues</h4>
<ul>
  <li>There are known major design issues in the TRANSPORT, ATS and CORE subsystems which will need to be addressed in the future to achieve acceptable usability, performance and security.</li>
  <li>There are known moderate implementation limitations in CADET that negatively impact performance.</li>
  <li>There are known moderate design issues in FS that also impact usability and performance.</li>
  <li>There are minor implementation limitations in SET that create unnecessary attack surface for availability.</li>
  <li>The RPS subsystem remains experimental.</li>
  <li>Some high-level tests in the test-suite fail non-deterministically due to the low-level TRANSPORT issues.</li>
</ul>
