    Upgrades from Fusion 5.8.0

    Fusion 5.8.1 fixed an issue with the Fusion 5.8.0 Helm chart that prevented horizontal pod autoscaling.

    If you are upgrading from Fusion 5.8.0 to any later version and use horizontal pod autoscaling, you must complete the procedure detailed in the Fusion 5.8.1 release notes.

    New Features

    • The new Consumption Dashboard tracks your request and document usage against the allotted consumption in your Fusion license. To access the dashboard, log into Fusion and go to Analytics > Consumption.



    • Fusion now supports Kubernetes 1.25 and 1.26. This applies to GKE, AKS, and EKS. It also applies to Rancher (RKE) and OpenShift 4 versions that are compatible with Kubernetes 1.25 and 1.26. Refer to Kubernetes documentation for versions 1.25 and 1.26 to decide which version to use for your deployment.

    • Added a new Admin button to the Rules Editor screen. Click on it to log out of Fusion.

    • Improved Spark Solr’s performance to ingest and transport data, as well as setting the most efficient sort for data export.

    Fusion Connectors

    • Updated the connectors-sdk library version to Java 11.

    • Updated Fusion to prevent automatically updating V2 connector plug-ins. Intentional updates allow you to verify related functions and operations.
