View multi-file diffs with commit preview

The latest GitHub for Atom release introduces two new features aimed at enhancing the code commit experience by improving diff rendering and providing a commit preview option. Previously, rendering diffs involved processing a large number of DOM elements, limiting the ability to load large or multiple diffs, but now, using Atom’s TextBuffer, performance is improved, allowing for more efficient loading and rendering of large and multiple diffs. This update also offers features such as editable diffs, code folding, syntax highlighting, and multi-cursor edits, making it easier to review and edit code. The commit preview feature allows users to see all staged changes in one pane, facilitating easier review and the creation of meaningful commit messages. User research informed the design changes, resulting in a more intuitive workflow and polished diff view. Future updates will focus on improving pull request reviews, and feedback is encouraged to refine the user experience further.
