The Stack Overflow Unofficial Patch (SOUP) is a Chrome extension developed by Ilmari Karonen. It aims to collect various minor client-side bug fixes, work-arounds, and usability improvements for Stack Overflow and other Q&A sites on the Stack Exchange Network. The intention of SOUP is not to make substantial or controversial changes to the Stack Exchange user interface, but rather to address minor problems and omissions that the SE developers may have overlooked or not yet fixed.

By combining these minor patches into a single user script, SOUP provides an easy-to-install and maintain solution for users. It now offers the same improvements as a Chrome extension, ensuring even greater accessibility.

For more information on the specific fixes included in SOUP, visit the linked Stack Apps page and the Github project.
