2025-08 monthly summary: Delivered a broad set of performance, reliability, and maintainability improvements across core server components and frontend tooling, with a strong emphasis on business value and scalable architecture. Key work included trash management enhancements (store folder hierarchy in trash and port Trashbin deletion to a node-based API), metadata deletion order fixes, and a targeted Trashbin N+1 fix in propfind, collectively reducing database load and improving data integrity. Continued scale and efficiency gains across data access patterns (filecache deletions, CalDAV/calendar properties, and preview pipelines), LDAP attribute refresh on login, and startup performance improvements via lazy Trashbin root initialization. Frontend modernization in profiler (Vue 3, Vite, Pinia) delivered a modern UI and improved developer experience. Substantial code quality and maintainability improvements and refactors (QueryBuilder migrations, Rector application, and CS fixer) plus CI/CD workflow enhancements further accelerate delivery and reliability across the codebase.
