• Provide an ability to define the device name at initialization time.

0.11.0 (2025-06-14)

• Try to automatically connect to devices with Manufacturer TeensyToAny. This requires firmware version 0.13.0 and up.

0.10.2 (2025-06-02)

• Fix I2C scanning command line utility by absorping the errors when no device is detected on the bus. Tested with a Teensy 4.0 and Sparkfun ISM330DHCX QWIIC board.
