During August 2025, Mingfei Fang updated documentation in the welovej/azure-rest-api-specs repository to guide users through the deprecation of the RetainedData feature. Mingfei clarified the migration path by recommending TaskCompletion for uploading task data to Azure Storage, ensuring backward compatibility and minimizing disruption. The work focused on API specification and documentation using TypeScript, emphasizing clear deprecation strategy and change management. No functional code changes were introduced, but the update reduced future support risks and aligned with established deprecation policies. Mingfei’s contribution demonstrated disciplined version control and provided customers with actionable guidance for adapting to evolving Azure API standards.
