 # Changelog
 
+## 0.16.5
+
+- Shows an accessible "Where does this temperature come from?" explanation on each zone and dashboard thermostat: weighted GREE/room formula, rounded result, source fallback and sensor status.
+- Adds fail-safe automatic-heating control: missing, stale or excessively different HA room readings cannot start or boost heat from the GREE fallback. Existing automatic heating turns OFF once compressor minimum-on protection permits. Manual control, cooling and GREE-only configurations are unchanged.
+- Displays blocked heating in the live thermostat status and "Why the controller works this way" control plan, including logs on guard activation/recovery.
+- Uses Home Assistant `last_reported` for freshness when available (otherwise `last_updated`), to avoid treating repeatedly reported stable readings as stale.
+- Extends the zone API diagnostics and ships Rust/UI regression tests plus the three day/night Flow examples.
+
 ## 0.16.4
 
 - Fixes a race in stateful Flow checkpoint saving: no stale condition evaluation can re-enable, overwrite or resurrect a disabled/deleted/recompiled automation.
