KNIME Business Hub 1.2 Release Notes

KNIME Business Hub 1.2.0

(released March 13, 2023)

KNIME Business Hub 1.1.1 to 1.2.0 Upgrade

• KNIME Business Hub 1.2.0 is expected to run in a Kubernetes 1.23.x cluster. Prior versions of KNIME Business Hub ran in Kubernetes 1.21.x clusters.
• For embedded kurl cluster installations, the cluster update process is to:
  • First, check for updates in KOTS Admin Console.
  • Once the KNIME Business Hub 1.2.0 update has been identified and preflight checks have been run, trigger the deployment.
  • After the deployment process has completed, run the following command in the terminal of the host machine to upgrade the Kubernetes cluster version (among other components):
    • curl -sSL [https://kurl.sh/knime-hub](https://kurl.sh/knime-hub) | sudo bash
    • You will have to enter y to various yes/no prompts during this upgrade process.
