Version?Type?Release Date?Availability?End of Support







Req. Data







Bug fixes and updates.

Advanced Warning

The following items are due to change in a future release.

  • Installation and Deployment

    • We aim to stop publishing the jar distribution of LogScale (e.g. server-1.117.jar) as of LogScale version 1.130.0.

      Users deploying via Docker images are not affected. Users deploying on bare metal should ensure they deploy the tar artifact, and not the jar artifact.

      A migration guide for bare metal deployments is available at How-To: Migrating from server.jar to Launcher Startup.

    • We intend to drop support for Java 17, making Java 21 the minimum. We plan to make this change in March 2024.


Items that have been deprecated and may be removed in a future release.

  • The assetType GraphQL field on Alert, Dashboard, Parser, SavedQuery and ViewInteraction datatypes has been deprecated and will be removed in version 1.136 of LogScale.

  • In the GraphQL API, the ChangeTriggersAndAction enum value for both the Permission and ViewAction enum is now deprecated and will be removed in version 1.136 of LogScale.

  • The humio Docker image is deprecated in favor of humio-core. humio is no longer considered suitable for production use, as it runs Kafka and Zookeeper on the same host as LogScale, which our deployment guidelines no longer recommend. The final release of humio Docker image will be in version 1.130.0.

    The new humio-single-node-demo image is an all-in-one container suitable for quick and easy demonstration setups, but which is entirely unsupported for production use.

    For more information, see Installing Using Containers.

  • In the GraphQL API, the name argument to the parser field on the Repository datatype has been deprecated and will be removed in version 1.136 of LogScale.

Improvements, new features and functionality

  • UI Changes

    • Time zone data has been updated to IANA 2023d.

    • Deletion of a file that is actively used by live queries will now stop those queries.

      For more information, see Exporting or Deleting a File.

  • Automation and Alerts

    • The following changes affects the UI for Standard Alerts:

      • A minimum time window of 1 minute is introduced, since anything smaller will not produce reliable results. Any existing standard alert with a time window smaller than 1 minute will not run, instead an error notification will be shown.

      • It is no longer possible to specify the time window and the throttle period in milliseconds. Any existing standard alerts with a time window or throttle period specified in milliseconds will have it rounded to the nearest second.

      • When saving the alert, the query window is automatically changed to the largest unit in the Relative Time Syntax that can represent it. For example 24h is changed to 1d and 60s is changed to 1m.

  • Configuration

  • Dashboards and Widgets

    • A series of improvements has been added to the dashboard layout experience:

      • New widgets will be added in the topmost available space

      • When you drag widgets up, all widgets in the same column will move together

      • Improved experience when swapping the order of widgets (horizontally or vertically)

  • Other

    • Live query cost metrics corrections:

      • livequeries-rate metric has changed from long to double.

      • livequeries-rate-canceled-due-to-digest-delay metric has changed from long to double.
