Custom search metadata for faceting
You can now attach your own key-value metadata to a page with the search-metadata frontmatter object. Fern copies the block onto every Algolia record for that page and declares each key for faceting, so a custom search integration can group and filter results by your own taxonomy.
Per-deployment values in self-hosted docs
A self-hosted container can now resolve environment variables in the pages it serves, on each request. A ${VAR} whose name is listed in FERN_RUNTIME_ENV_VARS is deferred past generation instead of being substituted with its build-time value, so one image serves deployments that differ only in those values.
