EduMatcher v0.77.0

[v0.77.0] - 2026-11-08

Release Type: major

📋 Summary

This release changes drop-copy sequencing to support independent per-gateway gap detection and replay. It also improves event delivery and auction-expiry reporting, adds bulk alert acknowledgement, and refines training and index workflows.

⚠️ Breaking Changes

• Changed drop-copy sequence numbers from a process-wide counter to per-gateway counters and made gateway_id required for replay; consumers must track sequence state per gateway and provide the gateway ID when requesting replay

✨ Additions

• Added bulk acknowledgement for log GUI alerts
• Added an optional reason to order.expired events to identify opening- and closing-auction expiries

🚀 Improvements

• Increased API gateway WebSocket event buffering and filtered delivery to subscribed event types, avoiding queued events clients would discard
• Improved index history, listing and restored-session phase handling

🐛 Bug Fixes

• Returned HTTP 409 for illegal session transitions in the REST API

📚 Documentation

• Updated drop-copy protocol documentation and examples for per-gateway sequence tracking
• Clarified training guidance for API-key creation and C examples, and updated the index and risk-control exercises

🛠 Internal

• Added regression coverage for drop-copy sequencing, auction-expiry reasons, WebSocket delivery and index restoration
