+    Legacy Temperature Sensor Driver is Removed
+    -------------------------------------------
 
     The legacy temperature sensor driver ``driver/temp_sensor.h`` is deprecated since version 5.0 (see :ref:`deprecate_tsens_legacy_driver`). Starting from version 6.0, the legacy driver is completely removed. The new driver is placed in the :component:`esp_driver_tsens`, and the header file path is ``driver/temperature_sensor.h``.
