## Changes
20220407: The default color order for pca9632 LEDs is now "RGBW". Add
an explicit `color_order: RBGW` setting to the pca9632 config section
to obtain the previous behavior.
20220330: The format of the `printer.neopixel.color_data` status
information for neopixel and dotstar modules has changed. The
information is now stored as a list of color lists (instead of a list
