Logstash 8.17.0 Release Notes

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 here.
