## Last updated frontmatter property

writing-content, frontmatter

You can now display a "Last updated" message in the page footer using the new `last-updated` frontmatter property. This helps readers know when the content was last modified.

```mdx
---
title: API Reference
last-updated: December 9, 2025
---
```

The date is displayed as-is in small text below the on-page feedback, so you can use any date format you prefer.

## Footer component for API Reference descriptions

api-reference, components, navigation

You can now use the `<Footer>` component in your API endpoint descriptions to add content that renders at the bottom of the page, below the response section. This is useful for related links, additional context, or notes that make more sense at the end of the endpoint documentation.

**`api/openapi.yml`**

```yaml api/openapi.yml
paths:
  /plants:
    get:
      summary: List all plants
      description: |
        Get a list of all plants in the system.

        <Footer>
        ## Related endpoints

        - [Create a plant](/api-reference/plants/create)
        - [Update a plant](/api-reference/plants/update)
        </Footer>
```
