GitHub Stacked Pull Requests Now Available in Public Preview
Content is AI-assisted and may contain inaccuracies.
GitHub has introduced stacked pull requests in public preview, giving developers a first-class way to break large changes into smaller, independently reviewable layers. Rather than cramming everything into a single monolithic PR, teams can now organize work into a linear stack where each PR builds on the one below it.
Reviewers get smaller, focused diffs that are easier to reason about, and authors can iterate faster with reduced risk of merge conflicts. Stacks can be merged one at a time as each layer is approved, or all at once when the full chain is ready. The feature is integrated directly into GitHub's pull request workflow and documented under the new stacked PRs guide.
