Two weeks ago, GitHub released support for Mermaid diagrams in files and most Markdown fields (see Include diagrams in your Markdown files with Mermaid). However, gists were missing support for Mermaid. Now, gists do support Mermaid diagrams just like discussions, issue comments, pull request comments, and files on GitHub. Still to come, and very important, is wiki support for Mermaid diagrams.

For more information about using Mermaid with GitHub, see Creating diagrams in the GitHub documentation.

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.
