Break large code changes into a chain of smaller, dependent pull requests you can review and merge independently.

Enable collaboration by allowing repository maintainers to commit changes to pull request branches created from forks in your personal account.

Modify the base branch of an open pull request to compare changes against a different branch and ensure accurate updates.

Create a pull request from a fork to propose changes to an upstream repository and collaborate on code effectively.

Create a stack of dependent pull requests using the gh stack extension in GitHub CLI or directly on GitHub.

Create new branches for development and delete unused branches directly on GitHub.

Restructure stacked pull requests, rebase their branches, and make changes to lower layers using GitHub CLI.

Merge a stack from the bottom up, individually, or in contiguous groups.

Understand how GitHub Actions workflows run for a stack, access stack metadata in your workflows, and reduce redundant CI usage.
