GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged be the repository owner. https://github.com/ repositories such as GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress.
