+title: "TemperatureConverter.convert_interval deprecation"
+---
+
+The method `convert_interval` in `TemperatureConverter` (allowing conversions between °F and °C intervals) has been deprecated in favor of `TemperatureDeltaConverter.convert`.
+The new converter and device class are now the preferred way to deal with temperature intervals.
