GitHub Pages now builds with GitHub Actions by default across all repositories.
For more details, see this blog post.
Earlier this year, GitHub added support for LaTeX style mathematical expressions and Mermaid diagrams in Markdown. However, until now, GitHub wikis were missing this support. You can now use these formatting features in GitHub wikis.
For more information about using mathematical expressions and Mermaid with GitHub, see creating diagrams and writing mathematical expressions in the GitHub documentation.
The GitHub Advisory Database now includes curated security advisories for vulnerabilities on GitHub Actions. This brings the Advisory Database to ten supported ecosystems, including: Composer, Go, Hex, Maven, npm, NuGet, pip, RubyGems and Rust.
If you have a dependency on any vulnerable GitHub Actions, GitHub will send Dependabot alerts over the coming days.
