Feb 1, 2026February 2026 summary for edgelesssys/contrast: Delivered two key improvements that drive deployment isolation and test reliability. Implementations include dynamic Kubernetes namespace creation driven by a configuration file, enabling automated per-deployment namespace setup, and a major test stability improvement by moving E2E test caching to a temporary directory to prevent cross-test interference. These changes reduce manual steps, shorten feedback loops, and improve overall CI reliability and deployment isolation.
