Bug fixes and updates.

Advanced Warning

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

  • Installation and Deployment

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


Changes that may occur or be required during an upgrade.

  • Configuration

    • We've migrated from Akka dependency component to Apache Pekko. This means that all internal logs referencing Akka will be substituted with the Pekko counterpart. Users will need to update any triggers or dashboards that rely on such logs.

      On Prem only: be aware that the Akka to Pekko migration also affects configuration field names in application.conf. Clusters that are using a custom application.conf will need to update their configuration to use the Pekko configuration names instead of the Akka configuration names.

Improvements, new features and functionality

  • Storage

    • Handling of IOExceptions in part of the segment reading code has been improved. Such exceptions will cause the segment to be excluded from the query, and potentially refetched from bucket storage, and a warning to be shown to the user, rather than cancelling the query.

  • Configuration

    • QueryMemoryLimit and LiveQueryMemoryLimit dynamic configurations have been replaced with QueryCoordinatorMemoryLimit, which controls the maximum memory usage of the coordinating node. This memory limit will, in turn, determine the limits of the static query state size and the live query state size. QueryCoordinatorMemoryLimit defaults to 400MB; QueryMemoryLimit and LiveQueryMemoryLimit defaults to 100MB regardless of their previous configuration.

      For more information, see General Limits & Parameters.

Bug Fixes

  • Dashboards and Widgets

    • The options for precision and thousands separators in Table widget have been fixed as they would not be saved correctly when editing other widgets on the Search page.

    • The hovered series in TimeChart widget have been fixed as they would not be highlighted in the tooltip.

    • The legend title in widget charts has been fixed as it would offset the content when positioned to the right.

  • Functions

    • The cidr() function would handle a validation error incorrectly. This issue has been fixed.

    • The count() function with distinct parameter would give an incorrect count for utf8 strings. This issue has been fixed.
