+Fix the docs embed `navigateToPage` API on multi-space sites. Deep-linking to a page in a different space/section (e.g. `navigateToPage('/help-center/integrations')`) previously 404'd because the section base was not placed before `~gitbook/embed/page`. The target is now resolved to its space server-side, so pages in any space resolve correctly. The input accepts the page path, an absolute path, or the full published URL.

+
+A near-white tint color (e.g. a warm `#F5F3EF`) is now taken as the exact page background, mirroring the existing behavior for near-black tints. The tint's exact lightness, hue and chroma are preserved, and the color is anchored to whichever scale step the active theme renders as the background — so it matches exactly on `muted` (which uses the second step) as well as `clean`. This applies only to near-neutral tints that are light enough to read as a background; saturated or merely light-ish colors keep their normal accent scale. The `bold` theme is unaffected: it already uses the tint for the header and stays intentionally two-tone.

+Add an `askQuestion` tool to the site MCP server. Alongside `searchDocumentation` and `getPage`, MCP clients can now ask a natural-language question and get a synthesized answer with links to the source pages, powered by the same AI search backend as the site's "ask a question" experience. The tool accepts an optional `goal` param so calling agents can attach the intent they're trying to accomplish, which tailors the answer and is tracked in analytics. The tool is only exposed on sites that have AI enabled.

+Remove GBO's redundant re-selection of the best-scoring search section. The search API now returns a single highest-scoring section per page (and orders sections highest-score-first), so GBO no longer needs its own `getBestScoredResult` helper to pick the best section for the search and MCP previews. No user-visible change.

+Fix a light/dark flash on published sites configured to respect the system default (no theme toggle). Such sites forced the `system` theme, but `next-themes`' pre-paint script applies a forced value verbatim without resolving `prefers-color-scheme`, so the page painted light and only switched to dark after hydration. We now leave the theme unforced when the default is `system` (only concrete light/dark themes are forced), letting `next-themes`' existing pre-paint script resolve the system preference before first paint.

+Fix the docs embed widget shipping a stale script: declare the embed package's `standalone/` bundle as a Turbo build output. Because it wasn't declared, changes confined to the standalone widget (which compiles to `standalone/` but not `dist/`) didn't invalidate the downstream `generate` cache that copies it into the app, so the deployed widget could lag the source — e.g. the `clipboard-write` permission on the widget iframe never reached production, breaking the copy button in the Assistant embed.

 # gitbook
 
+## 0.27.2
+
+### Patch Changes
+
+- bb30db1: Add a hover affordance in the document margin to ask the AI Assistant about a paragraph. On devices with a fine pointer, hovering a top-level paragraph reveals a small button that stages the paragraph's text as context and opens the assistant — making the existing text-selection "Ask" flow more discoverable.
+- 62ca6d3: Show a "Back to [space]" shortcut at the top of the table of contents when a reader follows a link into a different space, so they don't lose track of where they were browsing from.
+- fdea8f1: Show where a page lives in the site at the start of the page breadcrumbs: its section (including any enclosing section groups) and variant. Hovering any breadcrumb item reveals a dropdown to switch to its siblings at the same level — other section groups, sections, variants, page groups or pages — computed on the server from already-available data (no extra request). Language variants are left to the dedicated language picker rather than shown as a crumb. Also restyles the breadcrumbs to normal casing (matching search results).
+- 37c2dd8: Navigate customer visual tests with `domcontentloaded` to avoid `load`-event hangs on external sites.
+- c923c65: Fix center- and end-aligned paragraphs shifting left on wide/no-TOC pages when the AI Assistant is enabled, caused by the per-paragraph ask-button wrapper not inheriting the block alignment.
+- 37c2dd8: Fix flaky customer e2e screenshots by waiting for the built-in cookie banner before capturing.
+- 37c2dd8: Add a `data-testid` to the admin toolbar so e2e tests can assert its presence while hiding it from visual screenshots (it animates open, causing flaky diffs).
+- 36dbdb4: Support an optional `goal` query parameter on the markdown ask interface (`?ask=…&goal=…`), letting agents describe the broader end goal they are working towards so the answer can be steered towards it.
+- 7e55cd5: Add an "Available in MCP" badge on OpenAPI operations marked with `x-gitbook-mcp: true`. When `x-gitbook-mcp-url` is set (on the operation, path, or root — most specific wins), the badge becomes a button that copies the MCP server URL to the clipboard.
+- 6146f8e: Reduce the size of `searchDocumentation` MCP responses by returning only the best-matching section per page instead of concatenating every section body.
+- 37c2dd8: Disable the content max-width transition under reduced motion, matching the surrounding layout transitions.
+- 37c2dd8: Reset cross-space navigation state between e2e navigations so the "Back to <space>" shortcut can't leak in and cause flaky screenshots.
+- bcea23e: Render `anyOf`/`oneOf` with a `null` member as a nullable schema instead of a `null` union branch.
+- 77efd44: Show changed pages in preview toolbars for change requests and revisions.
+- 578a3a8: Fix site section dropdowns not being bounded by their container during the open/resize animation, causing the contents to visually clip.
+- 2dc76a2: Fix grouped top-nav section dropdowns rendering empty when the site is embedded in an iframe (visitor-auth embeds, editor preview) or shown in the embeddable view. The dropdown viewport is composited and animated, and a clipped composited layer fails to rasterize its text in Chromium when painted inside a sub compositing root; the rounded-corner clipping is now done on an inner wrapper so the viewport itself is no longer clipped.
+- 9f65133: Improve the 404 page: remove the table of contents sidebar and center the content, suggest related pages (ranked from the already-cached search index, so no extra request per 404), show a search or assistant input depending on the site's AI configuration, and move "Go to homepage" to the bottom as a last resort.

+- acf2719: Mark the AI Assistant chat as `aria-busy` while it is generating a response (including the follow-up suggestion phase), so assistive technologies are notified of the in-progress state.
+- 72a1596: Fix the AI assistant panel overflowing its frame when rendering single/multi-choice question forms with long option text.
+- 77c717c: Assistant: group all of a turn's tool calls behind a single "Explored with N tools" expandable instead of rendering a separate single-item expandable for each client-side tool call.
+- c44d822: Trust an optional cookieless integration content host (`GITBOOK_INTEGRATIONS_CONTENT_HOST`) for WebFrame postMessage, in preparation for isolating integration-rendered content onto a separate origin. Defaults to `GITBOOK_INTEGRATIONS_HOST`, so behavior is unchanged until the content host is configured.
+- 7655041: Match keyboard shortcuts by the logical character typed instead of the physical key position, so that ⌘-C no longer opens the Assistant on the Dvorak layout (and other non-QWERTY layouts).
+- af3cda1: Fix wide content (such as code blocks and tables) overflowing the edges of hint blocks instead of scrolling within them.
+- 0ca4952: Remove the external link button from the link tooltip hover card, as its arrow read as clickable even though the preview card isn't interactive.
+- 3ff88ba: Add a Prompt block
+- 251630c: Drive page actions ordering and default action from the new `pageActions.items` list, including the reorderable assistant action
+- ddba803: Add a page reference chip when opening the Assistant from the page action, so the assistant is informed about the page the reader is currently on.
+- f4469b2: Support OpenAPI one-operation-per-page mode
