QMK Breaking Changes - 2021 February 27 Changelog

Changes Requiring User Action

The following keyboards have had their source moved within QMK:

Old Keyboard Name New Keyboard Name
bear_65 jacky_studio/bear_65
s7_elephant/rev1 jacky_studio/s7_elephant/rev1
s7_elephant/rev2 jacky_studio/s7_elephant/rev2
aplx6 aplyard/aplx6/rev1
southpaw75 fr4/southpaw75

The Aplyard Aplx6 rev2 and the FR4Boards Unix60 have also been added as part of these changes.

Additionally, the handwired/bluepill/bluepill70 keyboard has been removed.

Core Changes

ChibiOS Update and Config Migration

QMK's ChibiOS and ChibiOS-Contrib submodules have been updated to version 20.3.2.

Along with this, QMK now provides default configuration files for all commonly-supported ARM microcontrollers running on ChibiOS. As such, keyboards are now only required to define settings which differ from the defaults, thereby reducing the size of pull requests for keyboards running atop ChibiOS.

QMK Infrastructure and Internals

Python is now required to build QMK. The minimum Python version has been increased to 3.7.

The power of info.json has been massively expanded. Most keyboard parameters can now be expressed in info.json instead of config.h/rules.mk. This should make maintaining keyboards easier, and will enable tooling that can allow non-technical users to add and maintain QMK keyboards without writing any code.

To ease migration a new command has been provided, qmk generate-info-json -kb <keyboard>. You can use this command to generate a complete info.json file for a keyboard and then remove the duplicate information from config.h and rules.mk.

Detailed example showing how to generate a new info.json and identify duplicate keys:

user@hostname:~/qmk_firmware/keyboards/lets_split:0$ qmk generate-info-json > new-info.json
user@hostname:~/qmk_firmware/keyboards/lets_split:0$ mv new-info.json info.json
