Graceful shutdown can be initiated on the client side by calling the new function <code>gun:shutdown/1</code> or when the owner process goes away; or on the peer side via the connection: close HTTP/1.1 header, the HTTP/2 GOAWAY frame or the Websocket close frame. Gun will try to complete existing streams when possible; other streams get canceled immediately. The <code>closing_timeout</code> option controls how long we are willing to wait at most before closing the connection. </li> +<li>Gun will better detect connection failures by checking the return value from sending data to the socket. This applies to all supported protocols. In addition, Gun now enables <code>send_timeout_close</code> with a <code>send_timeout</code> value defaulting to 15s. +</li> <li>Flow control has been added. It allows limiting the number of data/Websocket messages Gun sends to the calling process. Gun will stop reading from the socket or stop updating the protocol's flow control window when applicable as well, to apply some backpressure to the remote endpoint(s). It is disabled by default and can be applied on a per-request basis if necessary. </li> <li>An event handler interface has been added providing access to many internal Gun events. This can be used for a variety of purposes including logging, tracing or otherwise instrumenting a Gun connection. @@ -95,6 +97,10 @@ </li> <li>Many HTTP/2 options have been added, allowing great control over how Gun and the remote endpoint are using the HTTP/2 connection.
