New History Tab in GitHub for Mac

GitHub for Mac has introduced a completely redesigned History tab that offers a more efficient and faster way to view repository history, thanks to the integration of libgit2 for enhanced diff performance and ReactiveCocoa for improved responsiveness. This redesign marks the beginning of a broader vision for the app, with plans to extend similar improvements across other features. The update aims to significantly enhance user experience by providing a quicker and more responsive interface.
