TL;DR
GitHub has introduced support for stacked pull requests, allowing developers to submit multiple related PRs in a sequence. This new feature aims to improve workflow efficiency for large projects. The rollout is now live, with developers able to start using it immediately.
GitHub has officially launched support for stacked pull requests, a feature that allows developers to submit multiple related PRs in a sequence rather than as isolated changes. This development is designed to improve workflow management for complex projects and large teams. The feature is now accessible to all users, marking a significant update in GitHub’s code review capabilities.
According to GitHub’s official blog post, stacked PRs enable developers to create a chain of pull requests that depend on each other, simplifying the review process for large or multi-step changes. Previously, managing multiple related PRs involved complex workflows, often requiring manual coordination or separate branches. The new support allows for a more structured and transparent review process, with each PR clearly linked to its predecessor.
GitHub confirmed that the feature is now live and available to all users, with no immediate restrictions. Developers can start creating stacked PRs through the GitHub web interface or via Git command line tools, depending on their workflow preferences. The company has also provided documentation and tutorials to assist users in adopting the new system.
Early feedback from beta testers indicates that stacked PRs can reduce review overhead and improve collaboration, especially on projects with multiple interdependent changes. GitHub has emphasized that this feature is part of its broader effort to enhance developer productivity and streamline code management.
Implications for Large-Scale and Collaborative Development
The introduction of stacked PRs on GitHub provides a new method for managing complex code review workflows. By enabling developers to submit related PRs in a sequence, it aims to reduce review bottlenecks, improve transparency, and facilitate collaboration among team members. This feature is particularly relevant for large projects with multiple interdependent changes, where managing numerous PRs can be challenging.
For organizations and open-source communities, stacked PRs may help streamline integration cycles and improve review processes. It also aligns GitHub with other development tools that support chained or dependent changes, expanding its capabilities for handling complex development tasks.

Evolution of GitHub’s Code Review Tools
Prior to this update, GitHub users relied on traditional PR workflows, which often involved creating multiple branches and manually linking related changes. Some teams used workarounds such as referencing PR numbers in comments or external tools, but these methods were not integrated into the core platform.
The concept of stacked PRs has been discussed within developer communities for years, with some competing tools and platforms offering similar features. GitHub’s implementation of this support reflects ongoing industry trends toward more scalable and integrated code review solutions, especially for larger and more complex codebases.
The feature was announced in early 2024 after extensive beta testing with select users, including open-source projects and enterprise teams. Its primary goal is to improve the clarity and efficiency of managing multiple related changes in a single project environment.
“Being able to link multiple PRs in a chain simplifies the review process significantly, especially for large features.”
