Jul 1, 2025July 2025 highlights for GoogleCloudPlatform/k8s-config-connector: key features delivered include the MCP integration and evaluation framework for KCC, enabling MCP-enabled tasks, prompts, and reports with structured evaluation around GEMINI; comprehensive documentation updates with a README describing MCP evaluation workflow; and targeted maintenance that improved code quality (formatting, boilerplate cleanup) and maintainability through a rename of the MCP evaluation module to llm-eval. In addition, CRD versioning work established multi-version support, version comparison/backport readiness, and related tests, along with a controlled immutability adjustment for a GCP field. The LLM-eval surface was expanded with core enhancements (working directory handling, new flags, task-name handling, beta promote tasks, controller prompts) and Gemini path robustness, complemented by fixes in import handling and config resolution. Broader tooling improvements were completed for API promotion, sample handling, and promote-candidate workflows, with several quality fixes across the codebase.

Apr 1, 2025April 2025 monthly summary for GoogleCloudPlatform/k8s-config-connector. The team stabilized the feature surface while advancing security and release-readiness. Key outcomes include the introduction of read-only access for the cnrm-viewer role across Config Connector resources, plus updates to release notes and beta documentation to improve onboarding and release governance. At the same time, stability was preserved by rolling back two experimental changes that could compromise reliability: EdgeContainerVpnConnection CRD/mapper changes and SecretManagerSecret labeling features. These actions reduce risk for production deployments and set the stage for safer feature rollouts in future sprints.
