<p>We highly recommend all users upgrade to Flink 1.18.1.</p>
<p><strong>Note: Users that have <a href="https://nightlies.apache.org/flink/flink-docs-release-1.18/docs/ops/state/large_state_tuning/#compression">state compression</a>
should not migrate to 1.18.1 (nor 1.18.0) due to a critical bug that could lead to data loss. Please refer to <a href="https://issues.apache.org/jira/browse/FLINK-3406
