Improvements, new features and functionality

  • UI Changes

    • Toggle switches anywhere in the UI are now tabbable and can be accessed using the keyboard.

    • Improved keyboard accessibility for creating repositories and views.

  • Configuration

    • Default value of configuration variable S3_ARCHIVING_WORKERCOUNT raised from 1 to (vCPU/4).

    • Introduced new dynamic configuration flag JoinRowLimit. It can be set using GraphQL. The flag can be used as an alternative to the environment variable MAX_JOIN_LIMIT. If the join-row-limit flag is set, then its value will be used instead of MAX_JOIN_LIMIT. If it is not set, then MAX_JOIN_LIMIT will be used.

    • Introduced the new dynamic configuration QueryMemoryLimit. It can be set using GraphQL. The flag replaces the environment variable MAX_MEMORY_FOR_REDUCE, so if you have changed the value of MAX_MEMORY_FOR_REDUCE, please use QueryMemoryLimit now instead. See Limits & Standards for more details.

    • Added a link to humio-activity repository for debugging IDP configurations to the page for setting up the same.

    • Introduced the new dynamic configuration StateRowLimit. It can be set using GraphQL.

      • The Y-axis can now start at smaller values than 1 for logarithmic scales, when the data contain small enough values.

      • Isolated data points are now visualised as dots on the sparkline.

    • The Normalize option for the World Map widget has been replaced by a third magnitude mode named None, which results in fixed size and opacity for all marks.

  • Other

    • Fix a bug where changing a role for a user under a repository would trigger infinite network requests.
