What's Changed

This release introduces a new comment_style input with two options:

• legacy (default): one comment per target branch. This is the same behavior as you know from previous versions.
• summary: a single comment per workflow run that updates progressively as each target is processed. It links back to the workflow run, shows a status table for every target, and includes recovery hints for known failure modes (e.g. push permission denied, cherry-pick conflicts).

Here's what a summary comment looks like mid-run:

Backport-action is backporting this pull request in workflow run 15439584062.

Target	Status
stable/8.7	✅ Created #​612
stable/8.6	⚠️ Drafted with conflicts #​613
stable/8.5	❌ Failed
stable/8.4	➖ Skipped (PR already exists)
stable/8.3	⌛ Pending

❌ stable/8.5 — unable to cherry-pick

Tried to cherry-pick commits onto stable/8.5, but the cherry-pick failed.

Please cherry-pick the changes locally and resolve any conflicts.

git fetch origin stable/8.5
git worktree add -d .worktree/stable/8.5 origin/stable/8.5
cd .worktree/stable/8.5
git switch --create <backport-branch-name>
git cherry-pick -x a1b2c3d e4f5g6h

Opt in by adding comment_style: summary to your workflow:

- uses: korthout/backport-action@v4.5.0
  with:
    comment_style: summary

I'd love feedback on summary while it's opt-in. Drop a comment on #​611 with anything that's confusing, missing, or broken. Once it's proven stable in real workflows, I plan to make it the default and deprecate legacy in a future major release.

What's Changed

The new add_reviewers and add_team_reviewers inputs allow backport-action to request a review on the created backport pull request from the users and teams specified. These inputs can be used in simple setups where you want a particular user to always review, as well as in advanced setups where reviewers are determined in a separate workflow step. You can use these inputs in addition to any of the other reviewer inputs. Thanks for another great contribution @​mvlassis!

Backport-action no longer instructs users to force-push (with a lease) in the manual instructions for conflicts when using the draft_commit_conflicts option for the experimental conflict_resolution input. When running these instructions locally, the cherry-pick would fail due to conflicts, and the force push could push back the branch to its base, effectively closing the PR. This was confusing and added to the manual effort needed. Instead, users should resolve conflicts locally and push changes only when they are ready. Thanks for the fix @​ChrisKujawa!
