The recent launch week for Graphite introduced several new features aimed at enhancing developer collaboration and efficiency. Key announcements included the ability for multiple engineers to collaborate seamlessly on the same stack of pull requests (PRs) with automatic resolution of complex Git states. Additionally, Graphite now supports automatic rebasing of partially merged stacks, ensuring accurate diffs and correct reviewer assignments. The introduction of Graphite merge rules offers flexible branch protections and customizable code ownership, allowing teams to enforce specific requirements while maintaining compliance with company policies. A new batching workflow groups PRs for combined CI testing, which can reduce costs and expedite merging processes. Furthermore, integrations with Buildkite and GitHub Actions were introduced to help optimize CI pipelines, keeping releases reliable and costs manageable.
