Git's 'git blame' feature is a useful tool for developers to identify who last modified each line of code in a project, and it is often employed to prevent embarrassment by revealing that the author of questionable code might be the user themselves. To integrate this functionality into GitHub, a 'blame' link was introduced, which allows users to view additional details about code changes directly from the file view. This feature displays the commit's SHA, author, date, and message, and provides an option to drill down into previous commits to trace the history of changes to a particular line of code. This enhancement is designed to facilitate better understanding and accountability in collaborative coding environments.
