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.
