  * Rework rules.mk for keymaps to better handle arm vs avr support
* Start moving away from `matrix_*_*` functions.
  * `housekeeping_task_*` instead of `matrix_scan_*`
  * `keyboard_(pre|post)_init_*` instead of `matrix_init_*` 
* Add ℂℴmⅈℂ unicode input method.
* Clean up unicode code to be more compact and flexible.
* Remove/move Pro Micro LED commands to userspace and better filter them
* Fixup OLED code
  * Use newer quantum keycode functions/preprocessors rather than manual bit manipulation
  * Make unicode mode render much more compact/simple.
* Make qmk secrets more self contained
* Remove custom implementation of split watchdog
