MINOR: Mention in release notes
Reviewers: Mickael Maison Bruno Cadonna
by default in a future major release.</li>
<li>Kafka has replaced log4j and slf4j-log4j12 with reload4j and slf4j-reload4j due to security concerns.
More information can be found at <a href"https://reload4j.qos.ch">reload4j</a>.</li>
+ <li>The example connectors, <code>FileStreamSourceConnector</code> and <code>FileStreamSinkConnector</code>, have been
+ removed from the default classpath. To use them in Kafka Connect standalone or distributed mode they need to be
+ explicitly added, for example <code>CLASSPATH=./lib/connect-file-3.2.0.jar ./bin/connect-distributed.sh</code>.</li>
</ul>
