Logstash 6.0.1 Release Notes

edit
  • Elasticsearch Output: We now ignore an event’s type field for the purpose of setting the document _type if the cluster is Elasticsearch 6.x or above.
  • Fixed bug where plugins that used nested hashes for configuration would not work correctly
  • Improved shutdown process by ensuring that Logstash terminates on second SIGINT. Prior to this release, there were some situations where executing two SIGNINTs would not kill Logstash.
  • Fixed a bug where persistent queue could not be opened when in some states
  • Fixed an issue where the aggregate filter would not always shut down correctly
  • Fixed a large performance regression in the grok filter that has been with us since Logstash 5.x. Users should see a significant improvement in grok performance.
