KNIME Business Hub 1.18 Release Notes ​

KNIME Business Hub 1.18.0 ​

(released March 05, 2026)

Infrastructure Changes ​

  • Ingress-NGINX has been replaced by Istio Ingress Gateway as the ingress controller for KNIME Business Hub. (see Technical Upgrade Notes and Migration Playbook)
  • Secret store now stores secrets in Postgres by default (replaces default Vault/OpenBao on Replicated, and default MinIO on ArgoCD) (see Technical Upgrade Notes)
  • Azure Blob Storage Integration: Enable external cloud storage for Hub deployments on Azure via Azure Blob Storage, bringing feature parity with the existing AWS S3 integration and supporting ArgoCD/Helm-based deployments. (see Documentation)
  • MinIO “v2” Update: Hub installations now ship with minio-v2, based on a newer MinIO version, for improved stability and security.
    • Automatic migration from existing MinIO installations is not yet supported therefore existing installations upgrading to this version will continue using the previous MinIO version until a migration is performed.
    • Manual migration is supported, and KNIME will provide guidance and assistance for the process.
  • Istio Update
    • The bundled version of istio has been updated to 1.28.3. Clusters that have an externally managed installation of istio are recommended to update when possible to stay in sync with our tested version.

New Features ​

  • Remote Execution for KNIME Business Hub: Run and manage executors outside the Hub cluster (including on-prem, cross-region, or specialized hardware like GPUs/Windows) to ensure data residency, security, and maximum execution flexibility. (see Documentation)

Notable Bugfixes ​

  • Fixed an issue where jobs were not canceled after reaching the configured maximum execution time.
  • Fixed an issue where unexpected error pages were occasionally displayed when executing data apps.
  • Updated the default Azure OpenAI API version to 2024-08-01-preview to fix K-AI Q&A mode errors.
  • Fixed an input validation issue in executor management endpoints that could lead to unintended executor targeting.
  • Fixed an issue where updated license features were not immediately reflected due to caching in the accounts service.
