GitHub stacked pull requests hit public preview across every repo
Break big changes into ordered, reviewable layers and merge the whole stack at once via gh-stack. Plus: DeepMind disbands its AlphaFold team.
Copy markdown
Review layers in parallel, merge the stack in one click
Stacked PRs split a large change into ordered layers, each targeting the one below, so teammates can review different layers at once instead of blocking on one giant diff. Merge the whole stack or a single layer — the PRs above rebase automatically — and your branch protections and required checks still apply.
Turn it on today with gh-stack
Install it with `gh extension install github/gh-stack`; stacks also work on github.com, in the mobile app, and for coding agents like Copilot via a gh-stack skill. It is rolling out to all repositories now, with merge-queue support arriving over the coming weeks.
Elsewhere: DeepMind disbands its AlphaFold team
Reports say Google DeepMind has dissolved the Nobel-winning AlphaFold group, moving members onto Gemini and drug-discovery spinoff Isomorphic Labs; laureate John Jumper reportedly left for Anthropic in June. No changes were announced to the AlphaFold database or server, but it signals fewer open "grand challenge" science bets.
