October 2025 — OZ-Coding-School/oz_externship_be_03 monthly review focused on stabilizing and expanding the chat platform, while improving code quality and maintainability. Key features delivered include real-time chat with database persistence backed by an improved async ORM, plus new and updated APIs: Chat Room List, Message List with Read Receipts, and Message History. A WebSocket consumer and related tests were refactored per review feedback. Build and dependency stabilization was completed by adding channels-redis and unifying notification/chat dependencies and settings. Administrative cleanup (removing unused wiring), style/formatting cleanup (Black isort), and core model alignment with the develop branch were executed to reduce future CI risk and improve developer velocity. Cross-branch issues (Mypy path fixes, CI errors, and merge conflicts) were resolved to ensure smoother releases.
