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 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:
- PR is complete and ready to merge
- PR has a ChangeLog
