This document describes an upstream fix tracking (UFT) workflow. It lists the stable branches and development branches of various open source projects. The workflow takes the 6.1.x branch as an example, explaining the process of reading commits between releases and the master branch, filtering them based on keywords and blacklists, and sending the results to a Slack channel. It also provides some tasks for future improvement, such as adding hyperlinks to commits, supporting different repositories, and separating CVEs from fixes.
