GitHub Desktop 2.3 introduces new features designed to streamline the user experience by addressing common obstacles encountered during repository contributions. The update includes a solution for the confusion between cloning and forking repositories by automatically creating a fork when a user tries to push to a cloned repository, eliminating the need for complex "Git magic" to salvage work. Additionally, the update provides a warning when a user attempts to make changes on a protected branch without the necessary permissions, prompting them to create a new branch and continue their work seamlessly. These enhancements aim to prevent common frustrations and empower both new and seasoned developers to contribute to open source projects more effectively, while reducing the need for extensive tutorials and workarounds.
