(released Oct 01, 2025)

Before upgrading read the technical changes and upgrade notes here.

Updated hardware requirements ​

To improve service reliability, system security, and prepare for upcoming enhancements, we have increased the default memory requests for several Hub components. As a result, the hardware requirements for new Business Hub installations have changed. Please review the updated specifications here: KNIME Business Hub Change and Upgrade Notes.

Infrastructure changes ​

  • Support for using external databases and storage

    • Hub is not responsible for backup/restore operations of external Postgres and S3. AWS cloud services already provide data protection and should be utilized by customers.

  • Elasticsearch updated to 8.19.3

  • Keycloak updated to 26.1.4

  • Postgres update to Postgres 17

  • Executor pods will change their QoS mode from Guaranteed to Burstable. This has no practical impact in environments with dedicated execution nodes, and only minimal impact otherwise. The executor container will continue to run with requests = limits, but running in Burstable mode allows us to configure higher limits for the sidecar, making it more resilient.

Improvements / New Features ​

  • New sharing experience with unified look and feel across all entities (spaces, deployments, secrets, execution contexts and teams). This also includes an improved invite dialog for faster and easier sharing with other users as well as simplified sharing of Data Apps.
  • New "Delete all jobs" menu entries for deployments and execution contexts

Additional Changes ​

  • Data Apps Portal now shows all data apps to which a user has access, even if only implicitly shared via team membership.

Notable Bug Fixes ​

  • Fixed an issue where shareable data app links were automatically created when editing access to a deployment.
  • Helm templating error when enabling tolerations.
  • Fixed error in Swagger API documentation of service deployments.
  • Fixed error where moving a workflow via AP context menu "Move to…" didn’t cause a trigger deployment to run anymore.
  • Fixed bug where it could appear that a swapped job is still loaded on an executor.
  • Fixed issue where configured "Call workflow actions" would disappear in AP after a deployment was edited in Hub UI.

Fixed Vulnerabilities ​

  • HUB-10890 (5.3 / Medium, CVSS 4.0 Vector)

    • Open redirection could be used to redirect users to other malicious websites, allowing phishing-based attacks.

  • HUB-10226 (2.3 / Low, CVSS 4.0 Vector)

    • Job details such as input and output data were accessible to team members with permission to list the job.

New or Improved Data Apps ​

  • Idle Users Cleanup (docs, workflow) Free license seats by removing inactive users from teams. Schedule this workflow to regularly go over all teams, identify users that have no active deployments and didn’t log in within a specified number of days, and remove them from their teams. This makes them consumers, which don’t require a license seat. They can be added back to the team at any time to revert the changes.
  • Workflow Validation (docs, workflows) Make sure uploaded workflows are compliant with your requirements. Establish an automatic, semi-automatic, or manual workflow review process via the “Workflow validator” trigger deployment and “Request approval” / “Review workflow” Data Apps. The Workflow validator automatically checks the uploaded workflow and assigns an appropriate version label with an explanation, and the Data Apps let workflow builders and reviewers communicate for a manual review of the workflow version.
  • Customization Profile Application (docs, workflow) Fixed issues with detaching and applying Customization Profiles, removed Python dependency, updated KNIME Hub Connector, and simplified customization profile updates.
  • Extract Node Usage Histogram of KNIME Hub (workflow) Extract the node usage histogram of your KNIME Business Hub workflow repository, which is the occurrence count of nodes in the workflows.
  • Updated admin workflows to handle pagination in accounts endpoint (see changes in accounts service):

REST API Changes ​

  • Accounts service made some breaking changes in the response structure, e.g., when listing teams or users. For instance, the account names in the response of /accounts?type=user and /accounts?type=team used to be parseable as [**]['name']** and now need to be parsed as ['accounts'][]['name'].
