GitHub has introduced a new feature to enhance collaboration and review processes for prose documents by enabling both source and rendered views in commits and pull requests. This allows users to easily view text changes and complex structures like tables as they will appear in the final document by clicking the "rendered" button. Non-text changes are subtly highlighted with a dotted underline, and users can hover over the text to see specific modifications. This improvement underscores the importance of well-written prose in various aspects of software development, such as documentation, development planning, and knowledge sharing, ultimately contributing to the creation of better software products.
