+  <h1>GNUnet 0.16.0 released</h1>
+<p>
+  We are pleased to announce the release of GNUnet 0.16.0.
+<br>
+  This is a new major release. It breaks protocol compatibility with the 0.15.x versions.
+  Please be aware that Git master is thus henceforth (and has been for a
+  while) <b>INCOMPATIBLE</b> with
+  the 0.15.x GNUnet network, and interactions between old and new peers
+  will result in issues.  0.15.x peers will be able to communicate with Git
+  master or 0.16.x peers, but some services - in particular GNS - will not be compatible.<br/>
+  In terms of usability, users should be aware that there are still
+  <b>a 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 0.16.0 release is still <b>only suitable for early adopters
+  with some reasonable pain tolerance</b>.
+</p>

+<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>
