# Breaking Changes
|
|
|
|
This document describes QMK's Breaking Change process. A Breaking Change is any change which modifies how QMK behaves in a way that in incompatible or potentially dangerous. We limit these changes so that users can have confidence that updating their QMK tree will not break their keymaps.
|
|
|
|
The breaking change period is when we will merge PR's that change QMK in dangerous or unexpected ways. There is a built-in period of testing so we are confident that any problems caused are rare or unable to be predicted.

|
## What has been included in past Breaking Changes?
|
|
|
|
* [2019 Aug 30](ChangeLog/20190830.md)
|
|
|
|
## When is the next Breaking Change?
|
|
|
|
The next Breaking Change is scheduled for February 29, 2020.
|
|
|
|
### Important Dates
|
|
|
|
* [x] 2019 Sep 21 - `future` is created. It will be rebased weekly.
|
|
* [x] 2020 Feb 1 - `future` closed to new PR's.
|
|
* [x] 2020 Feb 1 - Call for testers.
|
|
* [ ] 2020 Feb 26 - `master` is locked, no PR's merged.
|
|
* [ ] 2020 Feb 28 - Merge `future` to `master`.
|
|
* [ ] 2020 Feb 29 - `master` is unlocked. PR's can be merged again.
|
|
|
|
## What changes will be included?
|
|
|
|
To see a list of breaking change candidates you can look at the [`breaking_change` label](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+label%3Abreaking_change+is%3Apr). New changes might be added between now and when `future` is closed, and a PR with that label applied is not guaranteed to be merged.
|
|
|
|
If you want your breaking change to be included in this round you need to create a PR with the `breaking_change` label and have it accepted before `future` closes. After `future` closes no new breaking changes will be accepted.
|
|
|
|
Criteria for acceptance:
|
|
|
|
* PR is complete and ready to merge
|
|
* PR has a ChangeLog
|

# Checklists
|
|
|
|
This section documents various processes we use when running the Breaking Changes process.
|
|
|
|
## Rebase `future` from `master`
|
|
|
|
This is run every Friday while `future` is open.
|
|
|
|
Process:
|
|
|
|
```
|
|
cd qmk_firmware
|
|
git checkout master
|
|
git pull --ff-only
|
|
git checkout future
|
|
git rebase master
|
|
git push --force
|
|
```
|
|
|
|
## Creating the `future` branch
|
|
|
|
This happens immediately after the previous `future` branch is merged.
|
|
|
|
* `qmk_firmware` git commands
|
|
* [ ] `git checkout master`
|
|
* [ ] `git pull --ff-only`
|
|
* [ ] `git checkout -b future`
|
|
* [ ] Edit `readme.md`
|
|
* [ ] Add a big notice at the top that this is a testing branch.
|
|
* [ ] Include a link to this document
|
|
* [ ] `git commit -m 'Branch point for <DATE> Breaking Change'`
|
|
* [ ] `git tag breakpoint_<YYYY>_<MM>_<DD>`
|
|
* [ ] `git tag <next_version>` # Prevent the breakpoint tag from confusing version incrementing
|
|
* [ ] `git push origin future`
|
|
* [ ] `git push --tags`
|
|
|
