Jan 1, 2026January 2026 (2026-01) performance summary for Siemens-Healthineers/K2s. Focused on reliability of the upgrade pathway and modernization of the monitoring stack. Delivered two impactful changes with clear business value: (1) upgrade installer enhancement to detect and manage duplicate executables, preventing conflicts and improving installation success rates; (2) monitoring addon migrated from Plutono to Grafana, updating deployment configurations, documentation, and related resources for a Grafana-based observability experience. Both initiatives involved code changes, documentation updates, and cross-team collaboration, contributing to more stable deployments and a modern, consistent monitoring footprint.

Dec 1, 2025December 2025: Strengthened security posture and deployment hygiene for Siemens-Healthineers/K2s. TLS verification enforcement across download and image workflows was implemented by removing insecure curl flags across scripts and commands, ensuring certificate validation for DICOM Web APIs, Debian checksums, base images, and related downloads. A security regression introducing SSL bypass was addressed by removing insecure SSL flags across components. TLS proxy certificate validation was implemented and SPDX licensing metadata added to the tls_proxy_check.go module. Documentation and registry naming were updated to Zot Registry and SSL flag usage guidance was enhanced. These changes reduce attack surface, ensure artifact integrity, and improve maintainability and compliance across the CI/CD and deployment pipelines.
