releases</a>.</em></p>
<blockquote>
<h2>Release 1.82.1</h2>
<h1>Security</h1>
<ul>
<li>server: Stop reading from the connection when flooded by HTTP/2
frames. The default value for this limit is 100 frames, excluding DATA
and HEADERS, and may be changed by setting environment variable
<code>GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT</code>.</li>
<li>xds/rbac: Support <code>Metadata</code> and
<code>RequestedServerName</code> permissions matcher fields. If present
in a DENY rule, previously these would be ignored and fail-open.</li>
<li>xds/rbac: Fix panic when parsing unsupported fields in
<code>NotRule</code>/<code>NotId</code> permissions.</li>
<li>xds/rbac: Support the deprecated <code>source_ip</code> principal
identifier by treating it as equivalent to
<code>direct_remote_ip</code>.</li>
</ul>
