QMK Breaking Changes - 2021 May 29 Changelog

Notable Changes :id=notable-changes

RGB Matrix support for split common (#11055) :id=rgb-matrix-split-common

Split boards can now use RGB Matrix without defining a custom matrix.

Teensy 3.6 support (#12258) :id=teensy-3-6-support

Added support for MK66F18 (Teensy 3.6) microcontroller.

New command: qmk console (#12828) :id=new-command-qmk-console

A new qmk console command has been added for attaching to your keyboard's console. It operates similiarly to QMK Toolbox by allowing you to connect to one or more keyboard consoles to display debugging messages.

Improved command: qmk config :id=improve-command-qmk-config

We've updated the qmk config command to show only the configuration items you have actually set. You can now display (almost) all of the available configuration options, along with their default values, using qmk config -a.

LED Matrix Improvements (#12509, #12580, #12588, #12633, #12651, #12685) :id=led-matrix-improvements

LED Matrix has been improved with effects, CIE1931 curves, and a task system.

Changes Requiring User Action :id=changes-requiring-user-action

Updated Keyboard Codebases :id=updated-keyboard-codebases

• Durgod keyboard refactor in preparation for adding additional durgod keyboards (#11978)
• Updated Function96 with V2 files and removed chconf.h and halconf.h (#12613)
• [Keyboard] updated a vendor name / fixed minor keymap issues (#12881)
• [Keyboard] Corne - Remove legacy revision support (#12226)

The following keyboards have had their source moved within QMK:

Old Keyboard Name	New Keyboard Name
crkbd/rev1/common	crkbd/rev1
function96	function96/v1
nckiibs/flatbread60	delikeeb/flatbread60
nckiibs/vaguettelite	delikeeb/vaguettelite
nckiibs/vanana/rev1	delikeeb/vanana/rev1
nckiibs/vanana/rev2	delikeeb/vanana/rev2
nckiibs/vaneela	delikeeb/vaneela
nckiibs/vaneelaex	delikeeb/vaneelaex
nckiibs/waaffle/rev3/elite_c	delikeeb/waaffle/rev3/elite_c
nckiibs/waaffle/rev3/pro_micro	delikeeb/waaffle/rev3/pro_micro

The Function96 V2 has also been added as part of these changes.

The codebase for the Durgod K320 has been reworked in anticipation of additional Durgod keyboards gaining QMK support.

Additionally, the crkbd/rev1/legacy keyboard has been removed.

Bootmagic Deprecation and Refactor (#12172) :id=bootmagic-deprecation-and-refactor

QMK has decided to deprecate the full Bootmagic feature and leave Bootmagic Lite as the only remaining option.

This pull request changes the behavior of BOOTMAGIC_ENABLE such that specifying BOOTMAGIC_ENABLE = yes enables Bootmagic Lite instead of full Bootmagic.

If attempts to use Bootmagic functionality result in unexpected behavior, check your rules.mk file and change the BOOTMAGIC_ENABLE setting to specify either lite or full.

Tentative Deprecation Schedule

This is the current planned roadmap for the behavior of BOOTMAGIC_ENABLE:

• From 2021 May 29, setting BOOTMAGIC_ENABLE = yes will enable Bootmagic Lite instead of full Bootmagic.
• From 2021 Aug 28, BOOTMAGIC_ENABLE must be either yes, lite, or no – setting BOOTMAGIC_ENABLE = full will cause compilation to fail.
• From 2021 Nov 27, BOOTMAGIC_ENABLE must be either yes or no – setting BOOTMAGIC_ENABLE = lite will cause compilation to fail.

Removal of LAYOUT_kc (#12160) :id=removal-of-layout-kc

We've removed support for LAYOUT_kc macros, if your keymap uses one you will need to update it use a regular LAYOUT macro.

Encoder callbacks are now boolean (#12805, #12985) :id=encoder-callback-boolean

To allow for keyboards to override (or not) keymap level code the encoder_update_kb function has been changed from void to bool. You will need to update your function definition to reflect this and ensure that you return a true or false value.

Example code before change:

void encoder_update_kb(uint8_t index, bool clockwise) {
    encoder_update_user(index, clockwise);
}

Example code after change:

bool encoder_update_kb(uint8_t index, bool clockwise) {
    return encoder_update_user(index, clockwise);
}
