GitHub Pages now uses Actions by default
As GitHub Pages, home to 16 million websites, approaches its 15th anniversary, we’re excited to announce that all sites now build and deploy with GitHub Actions.
We now detect and display submodules making it easy to see what other code is being referenced via our web interface.
If the submodule points to a repo on GitHub it will be automatically linked. If you hover over the short SHA1 for a few seconds you’ll see the submodule address and full SHA1 in a tooltip.
