 ## Changed
 
-- Discovery in HomeAssistant don't work with custom base topic. [#596](https://github.com/emsesp/EMS-ESP32/issues/596)
+- Discovery in HomeAssistant don't work with custom base topic. [#596](https://github.com/emsesp/EMS-ESP32/issues/596) Base topic containing `/` are changed to `_`
+- RF room temperature sensor are shown as thermostat
 
 ## **BREAKING CHANGES:**
 
-- MQTT Discovery (Home Assistant) entity names are now prefixed with the hostname, e.g. `select.thermostat_hc1_mode` becomes `select.emsesp_thermostat_hc1_mode`. You will need to recreate any custom dashboards.

 - When upgrading from 3.4.x you may need to erase the flash on the ESP32 before uploading the firmware. Make sure you make a backup of the settings and customizations via the WebUI (System->Upload/Download)
