 <p>Ranch 2.0 adds support for multiple connection supervisors.</p>
 <p>Ranch 1.x had a bottleneck because it used only a single connection supervisor. This was more evident when many connections were dropped at once as the supervisor couldn&apos;t keep up and failed to accept new connections while cleaning up the old ones. Ranch 2.0 behaves much better in this scenario by default. Multiple connection supervisors also helps with concurrently accepting new connections.</p>
 <p>Ranch 2.0 also adds experimental support for opening more than one listening socket on a single port.</p>
-<p>Starting with Ranch 2.0 we are also providing a Prometheus collector as a separate project as well as a Grafana dashboard.</p>

Numerous fixes were made that will also improve error recovery. Release upgrades will only be supported from Ranch 2.0 onward.
