Release notes for Headless version 4.4.0

🔧 SEO Improvements

Official Support for TYPO3 SEO APIs
- Page Title API (Documentation)
- MetaTag API (Documentation)
- Canonical API (Documentation)
Introduced page.seo Structure
- Adapted for Nuxt.js v3's useHead
- For Nuxt v3 applications, it's recommended to migrate to page.seo and have the backend developer remove page.meta.

To prevent breaking existing applications, ext:headless will continue to output page.meta.

Automated Meta Tag Generation: TYPO3 now generates all meta tags, including automatic canonicals and hreflangs (unless disabled by the backend developer).
Simplified Frontend Logic: The frontend app doesn't need additional logic for handling meta tags. Simply provide page.seo, and Nuxt.js does the rest.
Enhanced Backend Flexibility:
- Backend developers have access to PHP APIs to set tags and titles directly from plugins—no more fiddling with TypoScript.
- Tags can also be set via TypoScript, allowing quick additions without redeploying or modifying the frontend app.
