GitHub Ships Stacked Pull Requests in Public Preview

GitHub has made stacked pull requests native, ending a decade in which teams reached for Graphite, Sapling or homegrown scripts to split large changes into ordered, individually reviewable layers. Each PR targets the layer beneath it, rebasing is handled automatically, and merging the top ready PR lands every unmerged layer below it in one operation. Partial stacks can be merged, with the PRs above retargeting themselves. Branch protections and required checks still apply; merge queue support is rolling out over the coming weeks. A gh-stack CLI extension covers the terminal, alongside web and mobile.
