For example, if free disk space monitor had to stop reporting data because it could not parse external tool output that would break HTTP API <code>GET /api/overview</code> responses.</p> </li> </ul> <p>GitHub issue: <a href="/misc/goto?guid=4959005642780559650">rabbitmq-management#375</a>.</p> <ul> <li> <p>Stats are no longer emitted for connections that are not considered to be in the fully initialised state.</p> <p>GitHub issue: <a href="/misc/goto?guid=4959005642891030549">rabbitmq-management-agent#42</a></p> </li> <li> <p><code>POST</code> requests now instruct clients to close TCP connections.</p> <p>In some popular browsers (Chrome, Internet Explorer) a <code>POST</code> request followed by an immediate <code>GET</code>request<br /> would result in a 400 response. Other browsers do no exhibit this behaviour. Since HTTP API is not meant to be<br /> on the hot code path and most requests are <code>GET</code> ones, disabling persistent HTTP connections<br /> for <code>POST</code> requests is a reasonable trade-off.</p> <p>GitHub issue: <a href="/misc/goto?guid=4959006479684211793">rabbitmq-management#377</a></p> </li> <li> <p>Sample retention policies are now validated more strictly to avoid configurations that<br /> are not supported and will lead to exceptions.</p> <p>GitHub issue: <a href="/misc/goto?guid=4959005643000282168">rabbitmq-management-agent#41</a></p> </li> <li> <p>UI operation for binding deletion did not respect optional (extra) binding arguments.</p> <p>GitHub issue: <a href="/misc/goto?guid=4959005643127674765">rabbitmq-management#243</a></p> </li> </ul>
