Month: 2026-05. Summary: Delivered a major overhaul of Azure Resource Lease Management in azure-rest-api-specs, standardizing lease files across resource providers, updating start dates and durations, revising reviewers, and reorganizing PKI lease YAML for policy compliance. Implemented Resource Type Detection Enhancement to accurately identify new resource types from API paths via HTTP method validation. Strengthened governance and CI for ARM leases by updating CODEOWNERS and refining Actions comments to clarify modeling reviews and lease synchronization. Executed targeted lease fixes and restructurings (e.g., Microsoft.ErrorInsights lease, Program Enrollment path, Palo AltoNetworks lease, and ARM lease directory changes) to improve policy alignment, traceability, and operational efficiency. Business impact: reduced operational risk, faster onboarding of new resource providers, and clearer ownership with measurable CI improvements.

April 2026 — Mike Harder’s changes to mikeharder/azure-rest-api-specs focused on delivering an automated ARM leases validation workflow and tightening release governance. The ARM Leases Workflow Automation adds a GitHub Action to validate ARM leases, detect new Resource Provider Namespaces, validate lease content, updates documentation, and enables incremental TSP changes with auto-signoff logic for ARM changes when notReadyForARMReview is not present. The work also included stabilization of the workflow and documentation across reviews, improving consistency and review efficiency.
