June 2026: Delivered two feature-level improvements to expand testing capabilities and end-to-end coverage. Implemented an HTTP/2 cleartext probe server (agnhost-h2c-server) to support more comprehensive probe testing, and upgraded the agnhost end-to-end test image to 2.64.0 across all configuration files and manifests to ensure testing reflects the latest features and fixes. No major bugs fixed this month; focus was on feature delivery and test stability. These changes enhance testing reliability, reduce release risk, and demonstrate proficiency with HTTP/2, containerized test infrastructure, and manifest-driven CI.

May 2026 monthly summary for kubernetes/enhancements: Delivered TLS-enabled gRPC health probes (KEP-4939) to secure health checks for gRPC services directly in Kubernetes without extra binaries. Implemented with commit 1aa9acaf0cdb09b431bf690d152bfd84886052ca. No major bugs fixed this month for this repo.

Month: 2026-03 — Focused on reliability and observability improvements in Kubernetes. Delivered a critical bug fix to PSI metrics reporting: ensured PSI metrics are emitted even when the OS does not enable Pressure Stall Information, preventing zero metrics and improving observability of system performance metrics. This fixes metric gaps that could affect capacity planning and alerting. No feature releases this month; bug fix enhances monitoring fidelity across Kubernetes.
