<p>Cowboy <code>2.0.0</code> has been released!</p>
<p>This is the new stable version of Cowboy. There are no new releases planned for the 1.x version of Cowboy.</p>
<p>The highlights from the release are:</p>
<ul><li>HTTP/2 support!
</li>
<li>Websocket compression!
</li>
<li>Much simpler, cleaner interface. No more weird errors just because you discard the Req object.
</li>
<li>A new low-level interface that receives all events from every set of request and response. This replaces the awkward hooks from 1.0.
</li>
<li><a href="https://ninenines.eu/docs/en/cowboy/2.0/manual/">A much more detailed manual !</a>
</li>
</ul>
<p>A more complete list of changes can be found in the migration guide: <a href="https://ninenines.eu/docs/en/cowboy/2.0/guide/migrating_from_1.0/">Migrating from Cowboy 1.0 to 2.0</a>.</p>
<p>There are two planned feature releases after 2.0. Some features were temporarily removed and will be added back in 2.1. In 2.2 new features will be added to allow users to support the gRPC protocol. Full details <a href="https://github.com/ninenines/cowboy/milestones">in tickets</a>.</p>
<p>Feeling good about this release? Send money one-time or monthly via <a href="https://salt.bountysource.com/teams/ninenines">BountySource</a>. Thanks in advance!</p>
<p>As usual, any feedback is appreciated, and any issues should be reported by opening a ticket. Thanks!</p>
