    - `BrickletPtcV2()` takes an additional parameter to define the type of sensor. The options are `BrickletPtc.SensorType.PT_100` and `BrickletPtc.SensorType.PT_1000`. This only determines the resistance returned by the bricklet. The default is `BrickletPtc.SensorType.PT_100`.

    - `BrickletSegmentDisplay4x7V2.set_segments()` takes a `list`/`tuple` of 4 `int` instead of digit0, digit1, digit2, digit3. This is the same API as the older [Segment Display 4x7 Bricklet](https://www.tinkerforge.com/en/doc/Hardware/Bricklets/Segment_Display_4x7.html).
