 Self-hosted controller for GREE-compatible air conditioners with a local Web UI, thermostat zones, schedules, Home Assistant integration, history, notifications and a documented HTTP/WebSocket API.
 
-**Version: 0.15.20**
+**Version: 0.16.0**
 
-Version 0.15.20 adds the Visual Flow heating-curve block with graphical X/Y points, selectable temperature sources, linear interpolation and dynamic setpoint binding for thermostats, GREE targets and Home Assistant service actions.
+Version 0.16.0 improves heating stability with Home Assistant room-temperature sensor control, reliable Flow ownership, and safer shutdown behavior.

+- `zone_thermostat` writes the existing persistent Zone intent and wakes the normal thermostat cycle. `power=false` sends an explicit physical OFF to the assigned unit but does **not** change the persistent Zone `enabled` flag; Zone enable/disable remains an administrative control gate. A concrete Flow mode (`heat`/`cool`) is also written with the OFF frame so a stale device `dry`/`fan` mode is not retained; Flow `auto` remains an ownership policy and is never mapped to physical GREE Auto on OFF. While a zone is owned by `automation.flow`, the global outdoor-assist bias is suppressed so the Flow's own room-temperature thresholds remain authoritative. It can also issue one-shot granular vertical/horizontal louver commands to the assigned unit; these auxiliary fields do not take over thermostat ownership.
 - `group_action` calls the existing `control_group` path, including custom group targets.
 - `device_action` uses the existing `DeviceCommand` / automatic-device path.
 - `device_feature_action` uses the same path but compiles exactly one selected `DeviceCommand` field, leaving all other unit settings untouched.

 # Changelog
 
+## 0.16.0
+
+- Improves heating stability when Visual Flow automations use Home Assistant room-temperature sensors; the updated Igor, Jan, and Sypialnia Flow definitions use HA room readings directly for ON/OFF thresholds rather than relying only on zone temperature.
+- Shortens temperature-reached shutdown stabilization in the updated heating flows from 30 minutes to 30 seconds to reduce overshoot; keeps start stabilization and separate ON/OFF thresholds.
+- Preserves `automation.flow` ownership across thermostat control cycles so the internal controller does not apply conflicting adjustments.
+- Prevents the global outdoor-temperature assist from boosting targets for zones currently controlled by Flow; standalone thermostat control retains its existing behavior.
+- Makes heating OFF commands set `power=false` with `heat` mode explicitly to avoid retaining an unintended dry/fan mode.
+- Removes humidity-driven/Turbo activation paths from the updated heating flows and adds guarded Turbo shutdown and missing-sensor safeguards.
+- Synchronizes core, Home Assistant add-on, and custom integration versions to 0.16.0.
+
 ## 0.15.20
