⚠️ Material for MkDocs is now in maintenance mode

This is the last release of Material for MkDocs that will receive new features. Going forward, the Material for MkDocs team focuses on Zensical, a next-gen static site generator built from first principles. We will provide critical bug fixes and security updates for Material for MkDocs for 12 months at least.

Read the full announcement on our blog: https://squidfunk.github.io/mkdocs-material/blog/2025/11/05/zensical/

This release includes all features that were previously exclusive to the Insiders edition. These features are now freely available to everyone.

Note on deprecated plugins: The projects and typeset plugins are included in this release, but must be considered deprecated. Both plugins proved unsustainable to maintain and represent architectural dead ends. They are provided as-is without ongoing support.

Changes:

• Added support for pinned blog posts and author profiles
• Added support for customizing pagination for blog index pages
• Added support for customizing blog category sort order
• Added support for staying on page when switching languages
• Added support for disabling tags in table of contents
• Added support for nested tags and shadow tags
• Added support for footnote tooltips
• Added support for instant previews
• Added support for instant prefetching
• Added support for custom social card layouts
• Added support for custom social card background images
• Added support for selectable rangs in code blocks
• Added support for custom selectors for code annotations
