# 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.

#### 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`.

## Rebase `develop` from `master`
 | 
			
		||||
 | 
			
		||||
This is run every Friday while `develop` is open.
 | 
			
		||||
 | 
			
		||||
Process:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
cd qmk_firmware
 | 
			
		||||
git checkout master
 | 
			
		||||
git pull --ff-only
 | 
			
		||||
git checkout develop
 | 
			
		||||
git rebase master
 | 
			
		||||
git push --force
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
## Creating the `develop` branch
 | 
			
		||||
 | 
			
		||||
This happens immediately after the previous `develop` branch is merged.
