This release reworks NeoPixel to use PixelBuf for the internal pixel buffer. On Blinka and CircuitPython < 5 it now requires the pypixelbuf (2.0.0+) library to run. It implements the same API as _pixelbuf in CircuitPython 5.x. NeoPixels manipulation should be faster when using the native implementation.

So, if you are still using CircuitPython < 5, then either 1) upgrade to CircuitPython 5.x, 2)use NeoPixel < 6, or 3) install pypixelbuf.

If you are Blinka, please make sure you have adafruit-circuitpython-pypixelbuf >= 2.0.0 installed as well.

To use in CircuitPython, simply install the Adafruit CircuitPython bundle.

To use in CPython, pip3 install adafruit-circuitpython-neopixel.

Read the docs for info on how to use it.
