    Improvements

    • Fusion now supports Kubernetes 1.29. This applies to GKE, AKS, and EKS. It also applies to Rancher (RKE) and OpenShift 4 versions that are compatible with Kubernetes 1.29. Refer to Kubernetes documentation at Kubernetes v1.29 for more information.

    • The Jira and Confluence classic connectors now support GDPR mode.

    • The Graph Security Trimming query pipeline stage now supports two new types of access control lists (ACLs) in addition to the main ACL represented by the _lw_acl_ss field:

      • A "deny" ACL list (_lw_deny_acl_ss).

      • A "share" ACL list (_lw_share_acl_ss) for connectors such as SMB that support it.

    Bug fixes

    • Fixed an issue that caused counters from discarded query-service instances to be propagated to subsequent days, leading to inaccurate numbers on the Consumption Dashboard.

    • Fixed an issue that caused an NRT replica to be created even when nrtReplicas is set to 0.

    • Fixed an issue that caused Kafka poll timeouts and commit errors, primarily impacting the Sharepoint Optimized V2 connector.

    • This release fixes issues with several V1 connectors:

      • Fixed an issue that prevented the Jira Cloud V1 connector from handling 429 errors correctly.

      • Fixed an issue that prevented the Jira V1 connector from indexing attachments.

      • Fixed an issue that prevented the Salesforce V1 connector from indexing data and applying security trimming.

    • Fixed an issue that caused datasource jobs to time out prematurely when data takes some time to process.

    • Fixed an issue that sometimes led to connector crawls becoming stuck in an infinite loop.

    Deprecations

    • The Fusion Search Domain-Specific Language (DSL) is deprecated in this release. Be aware that it can cause significant performance degradation in queries.
