GitHub Pages, initially launched as an experiment, quickly gained popularity for allowing users to create custom personal and project sites, leading to the implementation of several new features. The platform updated Jekyll to version 0.5.0, enhancing its capabilities, and introduced project CNAME support, allowing users to link custom domains to project repositories, provided they have a paying account. The addition of custom 404 pages enables users to create personalized error messages, while the automatic integration of submodules facilitates shared functionality between repositories. A significant improvement to the backend infrastructure now ensures that new pages are set up in a few minutes rather than the original 10-15 minutes, reflecting ongoing efforts to enhance user experience and functionality.
