Support for Erlang/OTP 21 has been removed.</p> +<h2 id="_features_added">Features added</h2> +<ul><li>Metrics are now provided by <code>ranch:info/0,1</code>. Currently includes accepted/terminated connection counts per connection supervisor. +</li> +<li>Alarms can now be configured. The only alarm currently available is <code>num_connections</code>. When the number of connections goes over a configurable threshold Ranch will call the given callback. This can be used to programmatically shut down idle connections to make up space for new connections, for example. +</li> +<li>A <code>post_listen_callback</code> option has been added. It receives sockets immediately after the <code>Transport:listen/1</code> call. It can be used for some additional initialization of the socket, such as setting file permissions on Unix domain sockets. +</li> +<li>It is now possible to use TLS-PSK authentication without having to specify a default certificate for TLS < 1.3. +</li> +</ul> +<h2 id="_experimental_features_added">Experimental features added</h2> +<ul><li>The <code>inet_backend</code> option is now properly handled and tested for TCP listeners. This allows using the experimental <code>socket</code> backend. The <code>socket</code> backend is now tested with Ranch. Note that there are known issues and Windows support is not currently implemented. +</li> +</ul> +<h2 id="_changed_behaviors">Changed behaviors</h2> +<ul><li>Ranch will now remove unsupported SSL/TLS options where applicable. A warning will be logged when this happens. Options are only removed when they are not compatible with the selected TLS version and leaving them would prevent the listener from starting. +<p>The following options are removed when using TLS 1.1, 1.2 or 1.3: <code>beast_mitigation</code> and <code>padding_check</code>.</p> +<p>The following options are removed when using TLS 1.3 exclusively: <code>client_renegotiation</code>, <code>next_protocols_advertised</code>, <code>psk_identity</code>, <code>reuse_session</code>, <code>reuse_sessions</code>, <code>secure_renegotiate</code> and <code>user_lookup_fun</code>.</p> +</li> +</ul> +<h2 id="_added_functions">Added functions</h2> +<ul><li>The function <code>ranch_proxy_header:to_connection_info/1</code> converts PROXY protocol information to the same format as <code>ssl:connection_information/1</code>. Because there is little overlap only the <code>protocol</code>, <code>selected_cipher_suite</code> and <code>sni_hostname</code> will be available, however. +</li> +</ul> + + + + + + + + + + + + <nav style="margin:1em 0"> + + <a style="float:left" href="https://ninenines.eu/docs/en/ranch/2.2/guide/migrating_from_2.1/"> + Migrating from Ranch 2.1 to Ranch 2.2 + </a> + + + + <a style="float:right" href="https://ninenines.eu/docs/en/ranch/2.2/guide/migrating_from_1.7/"> + Migrating from Ranch 1.7+ to Ranch 2.0 + </a> + + </nav> + + + + +</div> + +<div class="span3 sidecol"> + + +<h3> + Ranch + 2.2 + + User Guide +</h3> + +<ul> + + <li><a href="/docs/en/ranch/2.2/guide">User Guide</a></li> + + + <li><a href="/docs/en/ranch/2.2/manual">Function Reference</a></li> + + +</ul> + +<h4 id="docs-nav">Navigation</h4> + +<h4>Version select</h4> +<ul> + + + + <li><a href="/docs/en/ranch/2.2/guide">2.2</a></li> + + <li><a href="/docs/en/ranch/2.1/guide">2.1</a></li> + + <li><a href="/docs/en/ranch/2.0/guide">2.0</a></li> + + <li><a href="/docs/en/ranch/1.8/guide">1.8</a></li> + + <li><a href="/docs/en/ranch/1.7/guide">1.7</a></li> + + <li><a href="/docs/en/ranch/1.6/guide">1.6</a></li> + +</ul> + +<h3 id="_like_my_work__donate">Like my work?
