Bug fixes and updates.

Advance Warning

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

  • Installation and Deployment

    • We are decommissioning the the Nexus server used to host Java-based LogScale installation binaries, with a tentative decommission date of August 14, 2026. To download Java-based LogScale installers, please send a request to logscalesuccess@crowdstrike.com to obtain a username & API token, which are required to download from our new distribution platform.

Deprecation

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

Upgrades

Changes that may occur or be required during an upgrade.

  • Security

    • Upgraded the dependency Jackson to version 2.21.3 to address a denial of service vulnerability.

      See their documentation here: Jackson: GitHub

    • Upgraded Netty to version 4.2.13 to address a number of security vulnerabilities. See Netty project for more information about Netty.

  • User Interface

    • The LogScale UI time zone database has been updated to the Internet Assigned Numbers Authority (IANA) 2026b release.

New features and improvements

  • Security

  • Automation and Triggers

    • The new Interval option has been added as an alternative to cron expressions or simple scheduling frequency for scheduled reports. This new option uses Relative Time Syntax modifiers (for example, @every 3h) allowing scheduled reports to run at regular intervals.

      For more information, see Create Scheduled Reports.

    • Email actions now support dynamic recipients using message templates. Most templates available in email subjects and bodies can also be used in the recipients list, including field references such as {field:fieldName} that resolve from event data at trigger time. Templates can constitute the entire recipient address (for example, {field:email}) or be embedded within an email address (for example, {field:username}@crowdstrike.com or {name}@example.com). This enables sending notifications directly to users referenced in log events, such as notifying a user whose login failed. Static and dynamic recipients can be mixed freely.

      Templates that produce large or multi-line output (such as {events}, {events_html}, or {url}) are not permitted in recipients. For filter alerts, which trigger on a single event, the recipient is calculated from that event. For other alert types, the recipient is calculated from the first event only, which may be problematic if events have different values for the field referenced in the recipient template.

      Warning: when using field references, ensure the query is scoped so that recipients only receive events relevant to them.

      For more information, see Dynamic Email Recipients.

  • GraphQL API

    • Added the new GraphQL endpoint removeFeatureOptInForAllOrgs. This endpoint allows cluster owners to remove feature flag opt-ins at the organization level for all organizations in the cluster for a specific feature flag.

      This simplifies cleanup after a feature flag rollout process that involved first enabling the feature flag on a subset of organizations before enabling it globally on the cluster.

  • API

    • An endpoint has been added to force a parser to recompile on a given node at /api/v1/invalidateParser. This endpoint requires the ManageCluster permission.

    • Added an ingest status endpoint at /api/v1/status/ingest. This endpoint exposes a node's ability to receive and handle incoming ingest requests.

      In the future, this endpoint will be used to signal whether all conditions necessary for ingesting have been met for recently-started nodes, such as whether lookup files have been synchronized. At present, no such conditions have been implemented and the endpoint always responds with 200 OK.

    • The following endpoint has been added:

      POST /api/v1/repositories/{repo}/queryjobs/{id}/newclient

      This endpoint creates a new client for an existing query, allowing multiple independent consumers to poll the same query session.

Fixed in this release

  • Security

    • Fixed an issue where BitBucket social login was failing due to Atlassian's CHANGE-3052 deprecation. BitBucket now requires OAuth2 access tokens to be sent as a Bearer token in the Authorization header rather than as a query parameter. This issue has now been resolved.

    • A discrepancy regarding organization name validation has been fixed. Previously, names could contain special characters and HTML tags when creating an organization. However, when updating said organization, stricter validation was applied that disallowed those characters and tags. The validation logic for creating and updating operations has now been properly aligned.

      Note

      Organization names can still contain the characters < and >.

  • Administration and Management

    • Fixed an issue where removing a node using the Cluster administration menu, with the REST endpoint DELETE /api/v1/clusterconfig/members/<node_id>, or with GraphQL API using the mutation clusterUnregisterNode could lead to data loss, even when the flag force/accept-data-loss was not set.

      A validation step has also been added that ensures data is properly replicated before allowing node removal, which may slightly slow the operation.

      The fix can be disabled via the feature flag RefreshClusterManagementStatsInUnregisterNode, which is scheduled for removal in version 1.252. If issues arise that lead to the need to disable the feature flag, inform support.

      For more information, see Best Practice: Contacting Support.

  • User Interface

    • Fixed an issue where syntax highlighting in the Query Editor could sometimes fail on large queries.

    • Fixed an issue where recalling a recent query would incorrectly display results as an event list instead of auto-selecting the appropriate visualization.

  • Storage

    • Fixed an issue where auxiliary files with no local segment were not included when calculating disk usage. Previously, the files would appear as system data for a node in the Cluster Overview page, when they are in fact LogScale data. As a result, the node would be able to fetch an auxiliary file without fetching the corresponding segment file as a valid part of execution.

    • Fixed an issue that could cause bucket storage uploads to throttle unnecessarily when lookup files were being deleted while LogScale attempted to upload them to bucket storage. LogScale was incorrectly treating this as an upload failure, causing exponential backoff to activate.

  • GraphQL API

    • Fixed an issue where saved queries could be created without a name, making them impossible to display in the UI. The name field in the GraphQL mutation createSavedQuery is now validated, and will fail when the value is empty or contains invalid characters.

  • Ingestion

    • A regression introduced in version 1.237 for parsers has been fixed. Previously, parsers were failing with the error message Parser failed with exception com.humio.jitrex.RegexCancelledException" despite previously operating above the timeout limit.

    • Fixed an issue where updating lookup files with more than one key column could cause an error that was reported to the user as an internal server error.

  • Dashboards and Widgets

    • The legend ordering for stacked bar charts now follows the order of the stack itself.

      For more information, see Bar Chart Widget.

  • Queries

    • Anchoring in regular expressions would produce incorrect prefilters. Specifically, this affected the $ anchor, which may optionally match a line terminator unless the multi-line flag is enabled. The resulting prefilter would incorrectly require anchoring at the end of the input, causing some valid values to be erroneously filtered out. This issue has now been resolved.

    • Fixed an issue in the Regular Expression Engine v2 where end-of-string anchors were not applied correctly in all cases, which could lead to incorrect query results.

    • Fixed an issue where, in rare cases, queries could go missing when reusing query sessions and submitting identical queries close together, causing a race condition.

    • Fixed an issue in the query scheduler where segments were not correctly closed when the feature flag AllowQuerySchedulerToBailOnSlowChunks was enabled, leading to occasional query starvation.

  • Auditing and Monitoring

    • An issue has been fixed where audit log entries exceeding 16KB would be truncated with an ellipsis character (...), causing the resulting JSON to be unparseable. The maximum string length for audit log JSON output has also been increased to 900KB.

  • Functions

    • The query function series() now correctly respects query memory limits.

    • The parseLEEF() function now correctly adds error messages to the @error_msg[] field when failing to parse. This aligns error reporting with other parse functions.

    • The parseCEF() function now correctly adds error messages to the @error_msg field when parsing fails, aligning error reporting with the behavior of other functions.

    • The sankey() function now displays a more specific warning when the number of source-target flows exceed the limit, instead of showing the more generic groupBy() function limit warning.

    • Fixed an issue where a recent feature that introduced the ability to look up files in other views using the syntax readFile(file://<path>), and to look up files in packages in other views using the syntax readFile("file://<otherview>/<scope>/<package>:<filename>") was not implemented for files served externally.

Known Issues

  • Storage

    • For clusters using secondary storage where the primary storage on some nodes in the cluster may be getting filled (that is, the storage usage on the primary disk is halfway between PRIMARY_STORAGE_PERCENTAGE and PRIMARY_STORAGE_MAX_FILL_PERCENTAGE), those nodes may fail to transfer segments from other nodes. The failure will be indicated by the error java.nio.file.AtomicMoveNotSupportedException with message "Invalid cross-device link".

      This does not corrupt data or cause data loss, but will prevent the cluster from being fully healthy, and could also prevent data from reaching adequate replication.

Improvement

  • Security

    • The default example text provided when setting up IP filters has been updated and deduplicated.

  • User Interface

    • The saved searches filter now matches against labels in addition to the search name.

    • Recent queries are now saved after the first results arrive rather than immediately after a search is initiated. This allows the system to correctly determine whether to store the current widget type for manually selected visualizations, or omit it for auto-detected visualizations, ensuring recalled queries display with the correct visualization.

  • Automation and Triggers

    • Labels are now one of the elements exported when exporting Amazon S3 actions to templates or packages. However, the field useProxyOption is no longer exported, in an effort to align consistently with other action types.

      For more information, see Action Type: S3.

    • Trigger errors and warnings are now shown and can be cleared regardless of whether the trigger is enabled or disabled.

      For more information, see Triggers.

  • Storage

    • A new environment variable, S3_STORAGE_STREAM_IDLE_TIMEOUT_SECONDS, has been introduced. The environment variable ensures that if an Amazon S3 provider fails to send any data for the configured time duration, the transfer is aborted instead of hanging indefinitely and blocking other transfers from being scheduled. When using this variable, it's important to note the following:

      • If not defined, the default duration value is 180 seconds.

      • This environment variable controls the stream idle timeout for both upload and download times.

      • While the timeout mechanism was already in place for S3 upload, it was not previously present for S3 download.

    • Segment fetches that perform segment merges and archving now each have the same priority as segment fetches for queries. As a result, they are prioritized on a first-come, first-served basis within this priority level.

      This change helps avoid starvation of segment merges and archiving processes in cases of slow bucket downloads, or large numbers of segment downloads for queries.

  • Configuration

    • The following environment variables have been added to control start rate limiting for the query coordinator:

      These environment variables allow for controlling an existing mechanism. No new mechanism is introduced. If these limits are reached, queries are delayed and do not start execution until later.

  • Ingestion

    • Improved the distribution of digest partitions onto nodes. The previous implementation would sometimes cause individual nodes to own clusters of partitions, causing hotspots. The new implementation distributes partitions across available nodes without this type of clustering.

  • Queries

    • Scheduled searches no longer start immediately when due to run. Instead, all scheduled searches due to start within a given minute are staggered over that minute, smoothing out the load on the query engine and improving overall query performance.

      For more information, see Automatic distribution within each minute.

    • LogScale's Search UI now populates events in subquery Table tabs using a direct lookup in the table used by the query. As a result, the subquery table tab is now populated with a single request, increasing its speed significantly.

      For more information, see Display tabs.

    • Added an optimization for OR character predicates in the Regular Expression Engine v2. Regexes such as the following are now significantly faster:

      regex
      [ab]{4}
      regex
      [Ee]xecution|[Mm]alware

      For more information, see Operators.

    • Added an optimization for case-insensitive regexes in the Regular Expression Engine v2. Many case-insensitive regexes are now up to approximately 30% faster than before.

    • Added an optimization for case-insensitive searching in the Regular Expression Engine v2. This optimization applies to most regular expressions containing a sequence of characters. For example, case-insensitive regular expressions such as /Twain/ and /(Tom|Sawyer|Huckleberry|Finn)/ are now up to twice as fast.

    • Segment reading has been optimized for certain scenarios, primarily where events contain a larger number of fields.

  • Fleet Management

    • The Fleet Management configuration editor has been upgraded and is now based on the extensible code editor CodeMirror. This improves page loading times across LogScale and NG-SIEM, and includes the following improvements:

      • Ingest tokens are hidden in the editor until actively selected.

      • Visual warnings are displayed for unused sinks.

      Note

      Auto-completion with all required fields automatically added is currently not available in the new editor.

  • Metrics and Monitoring

    • Three new utilization percentage fields have been added to the same logs that record queryCostPerMs:

      • queryUtilizationPercentage - approximates CPU time spent on the query as a percentage of worker capacity.

      • userUtilizationPercentage - approximates CPU time spent on the user's queries as a percentage of worker capacity.

      • orgUtilizationPercentage - approximates CPU time spent on the organization's queries as a percentage of worker capacity.

      These fields approximate how much CPU time is being spent within the time interval denoted by the corresponding queryCurrentTimespanMs, userCurrentTimespanMs, and orgCurrentTimespanMs fields. As the boundaries of this interval are approximate, it is possible for the utilization percentage to exceed 100%.

    • New logging fields have been added to make it easier to determine how much cost per millisecond a query is accumulating, as well as how much cost per millisecond the associated user and organization are accumulating across all their queries.

      The new fields are logged on query workers and measure cost per millisecond for the query, user, and organization respectively:

      • queryCostPerMs - cost per millisecond for the query.

      • userCostPerMs - cost per millisecond for the user across all their queries.

      • orgCostPerMs - cost per millisecond for the organization across all their queries.

      The time interval covered by each measurement is denoted by the queryCurrentTimespanMs, userCurrentTimespanMs, and orgCurrentTimespanMs fields. The interval can be controlled using the new QuerySchedulerCostMetricsLoggingIntervalSeconds dynamic configuration parameter, which defaults to 30 seconds.

      These fields are logged periodically when a measurement interval ends while a query is running, and are also included in the "Query Ended" logs produced by the worker.

  • Functions

    • Two improvements previously gated by cluster version for the correlate() function are now enabled by default, including for multi-cluster search scenarios where the minimum version is unknown:

      • The time bucket boundary off-by-one millisecond fix, previously applied only when all nodes in the cluster were running at least version 1.238.

      • Selective scanning, previously used only when all nodes in the cluster were running at least version 1.239.
