GitHub has released stacked pull requests into public preview. The feature breaks large code changes into an ordered series of smaller dependent pull requests that can be reviewed and merged independently. It addresses the difficulty of handling massive single PRs and follows prior internal use at companies such as Meta and Google. Engineer Jared Palmer contributed to the work before and during his time at the company. Official GitHub announcements and documentation confirm the public preview status, with links provided to the changelog and docs for further details.
