Month 2025-11 summary: Focused on reliability and observability improvements for the Tongyi Qianwen upload flow in the dify-official-plugins repository. Implemented a temporary file tracking mechanism and robust cleanup to prevent file leaks during base64 uploads, and enhanced logging for easier debugging and monitoring. The changes were applied across upload handling paths (generate_response and generate_stream_response) with a dedicated cleanup routine and safer finally blocks. This work improves long-running service stability and disk space management while enabling better incident diagnosis. The work aligns with ongoing quality and release goals, and includes updates to versioning as part of the release cycle. Key features delivered and major bugs fixed are driven by a single critical fix with broad reliability impact: Temporary File Leak Mitigation in Tongyi Qianwen Upload Handling.
