Bug fixes and updates

Breaking Changes

The following items create a breaking change in the behavior, response or operation of this release.

• Functions

  LogScale LTS version 1.258 will include a breaking change to subquery semantics for the worldMap() and sankey() functions. Result fields will no longer be automatically detected, and results must be assigned to a specific field - magnitude for worldMap() and weight for sankey() respectively.

  This change avoids unpredictable behavior in sub-queries, and allows further development on related systems. The following is an example of a query that is impacted by this change:

  logscale Reformat

  worldMap(lat=lat,lon=lon,magnitude={ w_squared := w*w | sum(w_squared) | magnitude := math:sqrt(_sum) })

  Currently, the query will be interpreted as:

  logscale Reformat

  worldMap(lat=lat,lon=lon,magnitude={ w_squared := w*w | magnitude := sum(w_squared) })

  From version 1.258, the math:sqrt part of the query will no longer be discarded.

Advance Warning

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

• Documentation

  Our documentation homepage, functionality, and content will undergo a series of improvements before the end of August 2026. As the volume of content on the site has grown significantly, we recognize that finding the right information can be challenging. These changes are designed to improve navigation, make content easier to find, and provide clearer distinctions between content areas.

  Functionality and Navigation

  • New Default Homepage — Improved navigation and organization to help you find information more quickly. The existing legacy homepage will remain available.

  • Curated Content Pages — Topic-specific pages that provide key resources tailored to different areas of the documentation. Each page includes:

    • Search scoped to that specific content area

    • Highlights of new and recently updated pages

  • Guided Workflow Pages — Step-by-step, page-by-page guides to help you learn about specific areas of LogScale.

  • Bookmark Groups — Organize bookmarks into custom groups to create your own categorized link collections.

  • Page Watching and Notifications — Monitor pages and content for changes, so you're always aware of updates to the content you use most.

  • Custom Homepage — Set a Curated Content page as your homepage, so visiting library.humio.com takes you directly to your preferred content area.

  Content Improvements

  • New CrowdStrike Query Language (CQL) Manual — A standalone manual covering:

    • Query structure and execution context

    • Internal data representation

    • Datatypes used in queries and functions

    • Function types, input and output values, and related functions

    • Common query patterns organized by use case and challenge

    • Guides for translating SQL to CQL

  • New Getting Data Out Manual — Covers the different ways to extract information from LogScale, including APIs, the search interface, dashboards, and automation.

  • New Getting Data In Manual — Covers the methods, tools, and integrations available for ingesting data into LogScale.

  • New Administration Manuals — Separate, dedicated manuals for Self-Hosted and Cloud customers.

  We will provide updates as each improvement becomes available — we welcome your feedback as the changes roll out.

• API

  Starting in version 1.258, the queryjobs endpoint will always use pagination, even when no pagination arguments have been given. When no arguments are provided, the endpoint will return the maximum page size and an offset of 0. Unless the dynamic configuration parameter QueryResultRowCountLimit has been raised from its default value, this will initially be the entire result.

  All clients should begin transitioning to use the paginated polling method ahead of version 1.258.

Deprecation

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

The GraphQL field meta has been deprecated and now requires authentication. It will be completely removed in LogScale 1.304. To achieve similar results, use the loginInfo and clusterConfig fields instead.

To temporarily opt out of the authentication requirement, the feature flag UnauthenticatedMeta can be enabled.

The userId parameter for the updateDashboardToken GraphQL mutation has been deprecated and will be removed in version 1.273.

Behavior Changes

Scripts or environment which make use of these tools should be checked and updated for the new configuration:

• GraphQL API

  After an organization is soft deleted using the removeOrganization mutation, you can now only call the following mutations on that organization:

  • recoverOrganization — Restores the organization to visible state.

  • rollbackOrganization — Fully deletes the organization under certain conditions and permissions.

  Previously, you could call any mutation on a soft-deleted organization.

Upgrades

Changes that may occur or be required during an upgrade.

• Security

  Apache Log4j has been updated to version 2.25.5 to address a medium severity Common Vulnerabilities and Exposures (CVE) item.

  Bouncy Castle Java dependencies have been upgraded to version 1.85.
