Breaking changes from PR message

[spring1843]

I'm seeing in the code that there is some functionality for breaking changes:

actions/packages/automatic-releases/src/main.ts

Line 222 in 9ecff5f

parsedCommitMsg.extra.breakingChange = isBreakingChange({

And here's the function that checks for breaking changes.

actions/packages/automatic-releases/src/utils.ts

Line 144 in 9ecff5f

export const isBreakingChange = ({body, footer}: {body: string; footer: string}): boolean => {

However I'm having a hard time making it work from PRs. We want to have some instructions for PRs that introduce breaking changes so that the notes are properly reflected in release notes.

I was able to make this work by directly committing to the main branch (here https://github.com/spring1843/karpenter/releases/tag/v0.101.126), but unable to make it work in a PR.

So the question is, where should the message BREAKING CHANGE: description be entered in the context of the PR?

Is it the PR title? The PR description body? The last line of the PR description body (i.e. footer)?

Or is it the title, body, footer of the commit you create when you merge a PR?
