+=== Logstash 8.17.0 Release Notes
+
+[[known-issues-8-17-0]]
+==== Known issue
+
+When upgrading Logstash to 8.12.0 or earlier, if the `jvm.options` was previously modified and not overwritten with the newest version,
+users may see a "deserialize invocation error" message causing the pipeline to crash. Users are affected if the Persistent Queue
+is enabled and the pipeline is processing messages larger than 20MB.
+The solution is to apply the default change contained in the newer 'jvm.options' file, as seen https://github.com/elastic/logstash/blob/main/config/jvm.options#L66-L82[here].
