Graphite has introduced a new feature that allows developers to collaborate on stacked pull requests (PRs) with their teammates in real-time, addressing a long-standing request from users. This functionality simplifies the complex process of managing collaborative stacks of PRs from multiple authors, which is challenging with standard Git. The feature, available from version 1.3.4 of the Graphite CLI, enables users to fetch, create, and submit changes using commands like `gt get`, `gt create`, and `gt submit`, thereby facilitating seamless teamwork where different team members can work on various parts of a feature simultaneously. Graphite's system automatically resolves the complex Git states that arise during collaboration, ensuring that when local changes are detected as more recent than remote ones, it rebases the local state to incorporate incoming changes without manual intervention. This advancement in collaborative stacking supports efficient division of labor and enhances the overall code review process, allowing teams to build complex features more effectively.
