# X_BREAKING_ON_MAIN

## Means

a change to `main` carries a `BREAKING —` entry under `[Unreleased]` while the major window is closed

## Typical cause

after v30, `main` ships minors and patches only; a break lands on `next` and reaches `main` when the window opens ([Stability](/stability)). Read from the pull request's base branch (`GITHUB_BASE_REF`) or the pushed branch, so a local run without either reads nothing

## Fix

`git rebase --onto next main`, then retarget the pull request: `gh pr edit --base next`
