User pings are PING frames sent by the user, with the corresponding PING_ACK resulting in a <code>gun_notify</code> message being sent to the user process. They can be used to measure latency or do other checks. +</li> +<li>The <code>reply_to</code> request option has been extended to accept a fun or an MFA that will be called when a reply must be sent to the user process. +</li> +<li>The <code>state_name</code>, <code>event_handler</code> and <code>event_handler_state</code> fields were added to <code>gun:info/1</code>. +</li> +<li>Update Cowlib to 2.15.0. +</li> +</ul> +<h2 id="_experimental_features_added">Experimental features added</h2> +<ul><li>Experimental support for HTTP/3 has been added. Websocket over HTTP/3 is not currently implemented. HTTP/3 support is disabled by default; to enable, the environment variable GUN_QUICER must be set at compile-time. +</li> +</ul> +<h2 id="_bugs_fixed">Bugs fixed</h2> +<ul><li>TLS 1.3 performs certificate validation independently from the handshake, which means that certificate errors can arrive after the handshake has completed. This is in part to support post-handshake authentication. Gun will now replace <code>{error, closed}</code> and similar socket errors with the TLS alert when possible, including for TLS over TLS and TLS over HTTP/2 scenarios. +</li> +<li>HTTP/2 tunneling has been improved: WINDOW_UPDATE frames are now properly sent, and flow control is handled. In addition closing the stream is better handled. This impacts both proxying scenarios as well as Websocket over HTTP/2. +</li> +<li>HTTP/2 will now properly send a NO_ERROR "error" code when initiating graceful shutdown. +</li> +<li>HTTP/2 will now properly track the number of streams currently running and immediately fail when the user tries to open a stream too many compared to what the server allows. +</li> +<li>Sometimes stray HTTP/2 timeout messages could be received, producing a log message. This was because they were not cleaned up on disconnect. Now they are. +</li> +<li>Socket errors were not properly handled when sending Websocket PONG frames. This has been corrected. +</li> +<li>Trying to send a Websocket frame over an HTTP connection (before the Websocket upgrade) will now result in an error sent to the user process. +</li> +<li>When connecting to HTTP via a Unix domain socket, Gun will now set the host header to "localhost" by default. Previously an invalid host header was sent. +</li> +<li>Data could be lost when switching to the raw protocol. This has been corrected. +</li> +<li>Documentation has been updated to describe the <code>notify_settings_changed</code> option; as well as to recommend disabling automatic reconnect when Websocket is used; and to provide context around potential security risks due to HTTP/2 compressed headers. +</li> +</ul> + + + + + + + + + + + + <nav style="margin:1em 0"> + + <a style="float:left" href="https://ninenines.eu/docs/en/gun/2.2/guide/internals_tls_over_tls/"> + Internals: TLS over TLS + </a> + + + + <a style="float:right" href="https://ninenines.eu/docs/en/gun/2.2/guide/migrating_from_2.0/"> + Migrating from Gun 2.0 to 2.1 + </a> + + </nav> + + + + +</div> + +<div class="span3 sidecol"> + + +<h3> + Gun + 2.2 + + User Guide +</h3> + +<ul> + + <li><a href="/docs/en/gun/2.2/guide">User Guide</a></li> + + + <li><a href="/docs/en/gun/2.2/manual">Function Reference</a></li> + + +</ul> + +<h4 id="docs-nav">Navigation</h4> + +<h4>Version select</h4> +<ul> + + + + <li><a href="/docs/en/gun/2.2/guide">2.2</a></li> + + <li><a href="/docs/en/gun/2.1/guide">2.1</a></li> + + <li><a href="/docs/en/gun/2.0/guide">2.0</a></li> + + <li><a href="/docs/en/gun/1.3/guide">1.3</a></li> + + <li><a href="/docs/en/gun/1.2/guide">1.2</a></li> + + <li><a href="/docs/en/gun/1.1/guide">1.1</a></li> + + <li><a href="/docs/en/gun/1.0/guide">1.0</a></li> + +</ul> + +<h3 id="_like_my_work__donate">Like my work?
