Support for displaying Mermaid diagrams has appeared on GitHub’s top list of feature requests since 2015. In its absence, many developers simply added screenshots to their Markdown. Today, we’re excited to add native support for Mermaid wherever Markdown is supported (e.g., issues, repositories, discussions, gists).
Great news. Currently that way I deal with mermaid diagrams in GitHub issues is either: a screenshot — which is static and a pair — or an external image to the mermaid live — a potential security issue.
This change will make me push mermaid diagrams a lot more with the team.
