GitHub gists now only show their 30 most recent comments when first displayed. You can click Load earlier comments… to view more. This allows gists that have many comments to appear more quickly.

As you may or may not know, gists are actually Git repositories. New gists are now created with a default branch name of either main or the alternative default branch name you've defined in your user settings. This matches how other repositories are created on GitHub.
