+<div class="paragraph"><p>Cowboy 2.4 focused on improving the HTTP/2 implementation.
+All existing tests from RFC7540 and the h2spec test suite
+now all pass. Numerous options have been added to control
+SETTINGS and related behavior. In addition experimental
+support for Websocket over HTTP/2 was added.</p></div>
+<div class="sect1">
+<h2 id="_features_added">Features added</h2>
+<div class="sectionbody">
+<div class="ulist"><ul>
+<li>
+<p>
+Add experimental support for Websocket over HTTP/2.
+  You can use the <code>enable_connect_protocol</code> option to
+  enable. It implements the following draft:
+  <a href="https://tools.ietf.org/html/draft-ietf-httpbis-h2-websockets-01">https://tools.ietf.org/html/draft-ietf-httpbis-h2-websockets-01</a>
+</p>
+</li>
+<li>
+<p>
+Add options <code>max_decode_table_size</code> and
+  <code>max_encode_table_size</code> to restrict the size of the
+  HPACK compression dictionary.
+</p>
+</li>
+<li>
+<p>
+Add option <code>max_concurrent_streams</code> to restrict the
+  number of HTTP/2 streams that can be opened concurrently.
+</p>
+</li>
+<li>
+<p>
+Add options <code>initial_connection_window_size</code> and
+  <code>initial_stream_window_size</code> to restrict the size of
+  the HTTP/2 request body buffers for the whole connection
+  and per stream, respectively.
+</p>
+</li>
+<li>
+<p>
+Add options <code>max_frame_size_received</code> and
+  <code>max_frame_size_sent</code> to restrict the size of
+  HTTP/2 frames.
+</p>
+</li>
+<li>
+<p>
+Add option <code>settings_timeout</code> to reject clients that
+  did not send a SETTINGS ack. Note that this currently
+  may only occur at the beginning of the connection.
+</p>
+</li>
+<li>
+<p>
+Update Ranch to 1.5.0
+</p>
+</li>
+<li>
+<p>
+Update Cowlib to 2.3.0
+</p>
+</li>
+</ul></div>
+</div>
+</div>
+<div class="sect1">
+<h2 id="_bugs_fixed">Bugs fixed</h2>
+<div class="sectionbody">
+<div class="ulist"><ul>
+<li>
+<p>
+Fix the END_STREAM flag for informational responses
+  when using HTTP/2.
+</p>
+</li>
+<li>
+<p>
+Receive and ignore HTTP/2 request trailers if any
+  for HTTP/2 requests. Request trailer information will
+  be propagated to the user code in a future release.
+</p>
+</li>
+<li>
+<p>
+Reject WINDOW_UPDATE frames that are sent after the
+  client sent an RST_STREAM. Note that Cowboy will not
+  keep state information about terminated streams
+  forever and so the behavior might differ depending
+  on when the stream was reset.
+</p>
+</li>
+<li>
+<p>
+Reject streams that depend on themselves. Note that
+  Cowboy currently does not implement HTTP/2&#8217;s priority
+  mechanisms so this issue was harmless.
+</p>
+</li>
+<li>
+<p>
+Reject HTTP/2 requests where the body size is different
+  than the content-length value. Note that due to how Cowboy
+  works some requests might go through regardless, for
+  example when the user code does not read the request body.
+</p>
+</li>
+<li>
+<p>
+Fix all existing test failures from RFC7540. This was
+  mostly incorrect test cases or intermittent failures.
+</p>
+</li>
