#QMK Breaking Changes - 2022 February 26 Changelog

#Notable Features {#notable-features}

#Default USB Polling rate now 1kHz (#15352)

The default USB Polling rate has been aligned across supported platforms to now be 1ms/1kHz.

Something something Lets go gamers!

#Split support for pointing devices (#15304)

Pointing devices can now be shared across a split keyboard with support for a single pointing device or a pointing device on each side.

See the Pointing Device documentation for further configuration options.

#Changes Requiring User Action {#changes-requiring-user-action}

#Legacy macro and action_function system removed (#16025)

The long time deprecated MACRO() and action_get_macro methods have been removed. Where possible, existing usages have been migrated over to core Macros.

#Create a build error if no bootloader is specified (#16181)

Bootloader configuration is no longer assumed. Keyboards must now set either:

• BOOTLOADER within rules.mk
• bootloader within info.json

#Rename AdafruitBLE to BluefruitLE (#16127)

In preparation of future bluetooth work, the AdafruitBLE integration has been renamed to allow potential for any other Adafruit BLE products.

#Updated Keyboard Codebases {#updated-keyboard-codebases}

The following keyboards have had their source moved within QMK:
