 ## Added
 
 - new command called `commands` which lists all available commands. `ems-esp/api/{device}/commands`
+- Home Assistant icons for memory and time
 
 ## Fixed
 
 ## Changed
 
 - new API. Using secure access tokens and OpenAPI standard. See `doc/EMS-ESP32 API.md` and [#50](https://github.com/emsesp/EMS-ESP32/issues/50)
+- `info` command always shows full names in API. For short names query the device or name directly, e.g. `http://ems-esp/api/boiler`
+- free memory is shown in kilobytes
 
 ## Removed
