Over the past year, GitHub has enhanced its email notifications for pull requests to provide more detailed information, addressing the inadequacy of previous sparse emails that offered minimal context. The updated emails now include a comprehensive overview of the pull request, featuring a commit summary, a list of changed files, and links to the unified diff and patch versions. This allows users to merge, view, comment, or interact with the pull requests more efficiently, either through the command line or directly online. The improvements aim to enhance the user experience, with further enhancements planned for the future, as indicated by Scott Chacon.
