    Improvements

    • Fusion now supports Kubernetes 1.27. This applies to GKE, AKS, and EKS. It also applies to Rancher (RKE) and OpenShift 4 versions that are compatible with Kubernetes 1.27. Refer to Kubernetes documentation for version 1.27.

    • Query service replica scaling has been improved.

    Fusion Connectors

    • Updated the Web V1 (classic) connector library to resolve issues for certain JavaScript-enabled web pages. While Fusion was not vulnerable to the Common Vulnerabilities and Exposures (CVE) 2023-4863, the connector updates allowed Lucidworks to also acknowledge and resolve that publicly-reported CVE.

    Bug Fixes

    • The connectors-backend service no longer fails to start when deploying to Openshift 4.12.

    • Fixed an issue where the Transport Layer Security (TLS) for Fusion Microservices could not be enabled and used.

    Known issues

    • New Kerberos security realms cannot be configured successfully in this version of Fusion.
