Logstash 8.15.2 Release Notes

Known issue

Logstash may fail to shut down under some circumstances when you are using Pipeline-to-pipeline communication. Check out issue #16657 for details.

Workaround: Add -Dlogstash.pipelinebus.implementation=v1 to config/jvm.options. This change reverts the PipelineBus to v1, a version that does not exhibit this issue, but may impact performance in pipeline-to-pipeline scenarios.

Notable issues fixed

Fixed a regression from Logstash 8.15.1 in which Logstash removes all quotes from docker env variables, possibly causing Logstash not to start #16456
