 # Changelog
 
+## 0.15.15
+
+- Adds a persistent emergency STOP to Dashboard → Global power. Activating it stores a restart-resistant safety gate, clears queued automatic compressor actions, pauses schedules/thermostat automation and makes a one-time attempt to power off enabled units; startup does not replay the OFF command.
+- Adds a green return-to-normal action that releases the safety gate and immediately re-evaluates current conditions without forcing devices ON.
+- Expands Control plan with a full-width “why the controller is acting this way” section showing per-zone control source/reason and the most recently triggered automations with trigger context.
+- Keeps emergency-stop state operationally separate from configuration backup/import, and documents the new `POST /api/house/emergency-stop` endpoint in the API/OpenAPI contract.

 ## 0.15.14
 
 - Fixes Home Assistant energy sampling in the packaged add-on when authentication comes from `SUPERVISOR_TOKEN`; background sampling no longer requires persisted manual URL/token fields.

 Local GREE HVAC controller packaged as a Home Assistant add-on, with Web UI, HTTP/WebSocket API, built-in Swagger API documentation, UDP discovery/control, `amd64` and `aarch64` support, ingress, and database backup from `/data/gree-controller.db`.
 
-Version 0.15.14 fixes Home Assistant Supervisor authentication detection for background energy sampling and centralizes runtime HA readiness checks, so the add-on uses Supervisor credentials consistently across entity discovery, sensor reads, Flow integrations and energy collection.
+Version 0.15.15 adds a persistent emergency STOP in Global power and expands Control plan with per-zone reasons and recent automation trigger context, so the add-on clearly shows why climate control is running, waiting or paused.
