GitHub Desktop's 2.5 release introduces the long-awaited feature of Git tags, allowing users to mark specific points in their project's history directly from the application. This enhancement, driven by user feedback, eliminates the need for command-line operations to create tags, thereby streamlining workflows by integrating tagging into the local GitHub Desktop environment. When users push to GitHub.com, any tags created are automatically included, and notifications are provided to ensure that unpushed tags are not overlooked. The update reflects GitHub's ongoing commitment to enhancing user experience by reducing context-switching and supporting a more seamless workflow, as discussed in Neha Batra's session at GitHub Satellite.
