EduMatcher v0.13.5

[v0.13.5] - 2026-07-04

Release Type: patch

📋 Summary

This patch release tightens API gateway configuration handling and strengthens pm-cverifier checks for gateway-related sections.
It also standardizes the API gateway process command name to match the gateway naming convention used across the project.

⚠️ Breaking Changes

• Renamed the API gateway process command from pm-api-gateway to pm-api-gwy; update scripts, automation, and operational runbooks that invoke the old command name
• Removed legacy singular api_gateway config compatibility and now require top-level api_gateways in engine_config.yaml

🚀 Improvements

• Improved pm-cverifier schema coverage for API gateway sections by validating api_gateways with runtime-loader semantics
• Improved config verification parity for post-trade and market-data gateway sections and tightened market-maker schema checks

📚 Documentation

• Updated user-guide, training, architecture, and design documents to consistently use pm-api-gwy
• Updated configuration and verifier documentation to reflect api_gateways-only support

🛠 Internal

• Expanded regression tests for API gateway config loading and verifier behavior around gateway section validation and legacy-key rejection

EduMatcher v0.13.0

[v0.13.0] - 2026-07-02

Release Type: minor

📋 Summary

This release introduces two new external-facing TCP gateways

1. pm-alf-gwy (text ALF1 protocol) and
2. pm-balf-gwy (binary BALF protocol).
   These new Gateways enable third-party trading systems to connect from external hosts over defined protocols without using the internal ZMQ bus.
   The internal trading console is renamed from pm-gateway to pm-alf-console to claify its role.

⚠️ Breaking Changes

• Renamed pm-gateway to pm-alf-console; any scripts, aliases, or systemd units invoking pm-gateway must be updated

✨ Additions

• Added pm-alf-gwy: new external-facing TCP gateway implementing the text-based ALF1 session protocol, with configurable gateway roles, rate limiting, heartbeat/idle timeouts, and disconnect_behaviour support
• Added pm-balf-gwy: new external-facing TCP gateway implementing the BALF binary protocol using fixed-size little-endian frames, full order lifecycle (new/cancel/amend), engine event delivery (ack/fill/cancelled/amended/expired), and deterministic reject-code classification
• Added reference C client (alf_client.c, alf_parser.c) and Python client (alf_client.py, alf_parser.py) for external ALF1 connections
• Added docs/user-guide/24-alf-gateway.md: full ALF gateway user-guide chapter with protocol reference and operator runbook
• Added BALF support to pm-config-gen and pm-cverifier

📚 Documentation

• Updated user guide to cover the new BALF and ALF gateways
