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.
This also includes any keyboard moves within the repository.
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 changes will be included?
To see a list of breaking change candidates you can look at the breaking_change
label. New changes might be added between now and when develop
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 develop
closes. After develop
closes no new breaking changes will be accepted.
Criteria for acceptance:
- The PR is complete and ready to merge
- The PR has a ChangeLog file describing the changes under
<qmk_firmware>/docs/Changelog/20220827
.- This should be in Markdown format, with a name in the format
PR12345.md
, substituting the digits for your PR's ID. - One strong recommendation that the ChangeLog document matches the PR description on GitHub, so as to ensure traceability.
- This should be in Markdown format, with a name in the format

Updating the develop
branch
This happens immediately after the previous develop
branch is merged to master
.
-
qmk_firmware
git commandsgit checkout master
git pull --ff-only
git checkout develop
git pull --ff-only
git merge --no-ff master
- 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 push upstream breakpoint_<YYYY>_<MM>_<DD>
-
All submodules under
lib
now need to be checked against their QMK-based forks:git submodule foreach git log -n1
- Validate each submodule SHA1 matches the qmk fork, e.g. for ChibiOS:
- Go to qmk/ChibiOS
- Compare the commit hash in the above output to the commit hash in the repository
- If there's a mismatch:
cd lib/chibios
git fetch --all
git checkout master
git reset --hard <commit hash>
git push origin master --force-with-lease
-
(Optional) update ChibiOS + ChibiOS-Contrib on
develop
