Sep 1, 2025September 2025: Implemented E2E test configuration standardization for apache/shardingsphere by renaming the database image property from 'image' to 'images' across test configurations and workflows, consolidating naming conventions, and improving test infra maintainability. This aligns with CI/CD practices and reduces misconfiguration risk.

Jan 1, 2025January 2025 monthly summary for apache/shardingsphere focusing on API simplification for metadata refresh. Delivered Database Metadata Refresh API Simplification by consolidating forceRefreshDatabaseMetaData into refreshDatabaseMetaData and removing the force flag, reducing API surface area and improving maintainability. This lays groundwork for more robust metadata refresh workflows and project health.
