# QMK Breaking Change - 2020 Nov 28 Changelog
|
||
|
||
Four times a year QMK runs a process for merging Breaking Changes. A Breaking Change is any change which modifies how QMK behaves in a way that is incompatible or potentially dangerous. We limit these changes to 4 times per year so that users can have confidence that updating their QMK tree will not break their keymaps.
|
||
|
||
|
||
## Changes Requiring User Action :id=changes-requiring-user-action

### Relocated Keyboards :id-relocated-keyboards
|
||
|
||
#### Reduce Helix keyboard build variation ([#8669](https://github.com/qmk/qmk_firmware/pull/8669))
|
||
|
||
The build commands for the Helix keyboard are:
|
||
|
||
```
|
||
make <helix_build_name>:<keymap_name>
|
||
```
|
||
|
||
For `<helix_build_name>`, specify the one in the rightmost column of the table below, such as `helix`,` helix/pico`.
