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
