Jun 1, 2025June 2025 — Focused on enabling safer FSM transitions in blazingmq by adding a configurable QLIST persistence option (doesFSMwriteQLIST) that controls whether the broker continues writing to the QList file when the FSM workflow is enabled. This delivers backward compatibility and operational flexibility during FSM transitions, reducing risk during upgrades and deployments. No major bug fixes recorded for this repo this month; main effort centered on feature delivery and code quality.

Nov 1, 2024November 2024: Implemented a critical data integrity fix in blazingmq by preserving purge records when an application with virtual storage is deleted. This prevents purge records from being removed prematurely, improving data integrity for purged queues and application keys and ensuring purge lifecycle aligns with application state.
