Summary
GitHub launched stacked pull requests in public preview on July 30, 2026, letting developers break large changes into an ordered series of small, independently reviewable pull requests that merge together in one click, built into the native PR workflow with no waitlist or enterprise plan required.
What changed
GitHub made stacked pull requests available in public preview to any repository, adding native support for ordered PR stacks where each PR targets the layer below it, each can be reviewed and checked independently, and the whole stack merges in a single click across github.com, the CLI, mobile, and Copilot via a gh-stack skill.
Why it matters
Teams that split large changes previously relied on external tools or manual branch juggling; native stacking keeps the workflow inside existing review rules, checks, and merge requirements, reducing rebase overhead and making incremental review the default rather than a bolt-on.
Evidence excerpt
Stacked pull requests break large changes into small, reviewable pull requests. You can independently review and check each pull request, then merge everything together in one click. Works from github.com, the GitHub CLI, the mobile app, or an agent like GitHub Copilot using the gh-stack skill.
