<h3><a id="streams_api_changes_410"
href="#streams_api_changes_410">Streams API changes in 4.1.0</a></h3>
<p><b>Note:</b> Kafka Streams 4.1.0 contains a critical memory leak bug
(<a href="https://issues.apache.org/jira/browse/KAFKA-19748";>KAFKA-19748</a>)
that affects users of range scans and certain DSL operators (session windows,
sliding windows, stream-stream joins, foreign-key joins). Users running Kafka
Streams should consider upgrading directly to 4.1.1, which includes the fix for
it.</p>
