TL;DR
GitHub has officially launched its new stacked pull requests feature, allowing developers to organize and review multiple related PRs more effectively. The feature is now accessible to all users, aiming to streamline complex code changes.
GitHub has officially launched its new stacked pull requests feature today, enabling developers to organize multiple related PRs in a hierarchical, layered structure. This development aims to improve the review process for complex code changes, making it easier to handle dependencies and related updates within projects.
The feature, now accessible to all GitHub users, allows developers to create a series of linked PRs that are visually stacked in the interface. This setup helps reviewers understand the context of each change and the dependencies between different PRs, especially in large or multi-part projects.
According to GitHub’s official blog post, stacked PRs are designed to improve collaboration efficiency by reducing confusion and streamlining the review workflow. The feature supports nesting PRs, so developers can break down large changes into smaller, manageable chunks while maintaining a clear overview of the overall project.
Developers can now create a primary PR that references other PRs as dependencies, which automatically appear in a stacked view. Reviewers can then navigate through the layers, comment on specific parts, and approve or request changes at each level independently.
GitHub has confirmed that the feature is available immediately to all users via the web interface and GitHub CLI, with plans to introduce further integrations and enhancements in upcoming updates.
Enhanced Collaboration and Workflow Management
The launch of stacked PRs on GitHub represents a significant step toward improving how development teams handle complex, multi-part code changes. By enabling hierarchical organization, this feature helps reduce review time, prevent misunderstandings, and facilitate better collaboration, especially in large-scale projects with multiple dependencies.
For open-source and enterprise teams alike, this could lead to faster release cycles and more efficient code quality assurance processes, ultimately benefiting project maintainers and contributors.

Previous Efforts to Improve PR Management
Prior to this launch, developers relied on linear PR workflows, which often became cumbersome for large or interconnected changes. GitHub has experimented with various features like draft PRs and review workflows, but managing multiple PRs related to a single feature or fix remained challenging.
In recent months, there had been rumors and beta testing reports about GitHub developing a layered PR management system, but the official rollout confirms that the feature is now generally available.
