Logstash 8.4.0 Release Notes

edit

New features and enhancements

edit

Improvements to the dead letter queue (DLQ)

edit

This release brings significant improvements to help users manage their dead letter queues, including:

  • A new clean_consumed option on the Dead Letter Queue input plugin. It can automatically delete segments from a dead letter queue after all events in the segment have been consumed by a Logstash pipeline.
  • A new age retention policy, enabling the automatic removal of segments from a dead letter queue based on the age of events within those segments.
  • Additional dead letter queue metrics available from the monitoring API #14324

New AWS integration plugin

edit

Several AWS plugins are now bundled in a single AWS integration plugin, enabling easier maintenance and upgrades of AWS-based plugins. They all use version 3 of the AWS Ruby SDK.

JDK17 support

edit

Logstash now comes bundled with JDK17, while still providing compatibility with user-supplied JDK11. The new JDK includes an update pertaining to a potential security vulnerability. Please see our security statement for details.

Logstash M1 download

edit

Logstash is now available for download on M1 equipped MacOS devices, and comes bundled with M1 native JDK17.

Notable issues fixed

edit
  • Remove /etc/systemd/system/logstash.service only when file is installed by Logstash #14200
  • Fix Arcsight module compatibility with Elasticsearch 8.x #13874
  • Ensure that timestamp values are serialized with a minimum of 3 decimal places to guarantee that millisecond precision timestamps match those from Logstash 7.x #14299
  • Fix issue with native Java plugin thread-safety and concurrency #14360
  • Allow the ability to use Ruby codecs inside native Java plugins #13523
