GitHub opens stacked pull requests to all repositories in public preview
GitHub is rolling stacked pull requests out to every repository in public preview — a large change splits into an ordered series of layers, each reviewed and checked on its own, and merging one layer automatically rebases and retargets the layers above it. Installing the gh-stack CLI extension puts that workflow in a developer's hands today, with existing branch protections and required checks still governing what reaches the default branch. Merge queue support arrives over the coming weeks.

A big change used to mean one giant PR nobody wanted to review. Now it's a stack of small ones reviewers can actually follow, and the whole stack merges in one shot.

Why this matters
- → Eliminates the large-PR review bottleneck — small, parallel-reviewable layers ship faster.
- → Merge queue integration + auto-rebase keeps branch integrity without manual rebasing.
- → Built into GitHub — existing checks and protections work immediately, no new tools needed.
