Recently shipped dynamic OG images by default, a draggable Ask AI widget, and availability-based endpoint sorting.

**Shared links now render preview cards automatically.**
Pages without a site-wide `og:image` or `twitter:image` now get a generated preview image, so shared links show a card instead of a blank placeholder. Frontmatter `og:image` still wins; set `og:dynamic: false` under `metadata` in `docs.yml` to opt out.

**The Ask AI chat widget is now draggable.**
Visitors move the standalone `AskAiChat` widget by its header or launcher button; the card follows and stays inside the viewport, opening above or below the launcher depending on room. Dragging is on by default in `@fern-api/search-widget` 0.6.0; pass `draggableCard={false}` to pin the chat to its `placement` corner.

**API References sort by availability and read specs directly.**
- `sort-by-availability` puts endpoints with the values you name first — `beta`, `deprecated` — then the rest in default order. `unset` positions endpoints with no availability, and `alphabetized: true` sorts within each group.
- An `api` navigation item now takes a `specs` list of OpenAPI, AsyncAPI, or GraphQL files with optional overrides, overlays, and namespace — no `generators.yml` required. Existing `api-name` setups are unchanged.

**Agent-facing docs gained PHP output and leaner indexes.**
- `/llms.txt` and per-page `.md`/`.mdx` URLs accept `lang=php`, joining the existing language filters, to return PHP SDK examples only.
- `excludeChangelog=true` drops changelog sections from `llms.txt` for sites with long release histories.
- Missing `.md` requests now return up to five similar-page suggestions instead of three.
