Release notes

---

What's new

• We have introduced a LogToFile setting. The components no longer write their own log files by default, which removes disk writes from the trading path. All messages still appear in the MT5 journal.

---

Bug fixes

• We have resolved the spurious error messages reported by the MT5 External Order Listener plugin when it runs on a History (non-main) server after an upgrade, and hardened plugin startup to prevent a crash seen in certain builds.

---

Misc

• We have introduced Prometheus thread metrics for MT5ExternalOrderListener plugin. Component now collects per-thread latency histograms, memory usage gauges, and a component-level last_update timestamp, exposing them via the heartbeat response to the Configuration API every 5 seconds.

---

Bug fixes

We have fixed 2regressions in the MT5 ExternalOrderListener plugin:

   - the build version is once again reported correctly in the startup log;

   - the Use32BitSettlementDate setting is now preserved across plugin restarts 

---

Bug fixes

• We have fixed an issue introduced in v26.4.83 where, after the MT5 ExternalOrderListener plugin migrated its configuration to a local file, all external order sender logins were rejected as "does not have permissions" once the plugin restarted.
