 ## Image handling improvements

 - **Major improvement**: Images no longer cause layout shift by default, even when width and height attributes aren't specified—automatic sizing prevents content jumping during page loads
 - All static files in your repository (PDF, TXT, XML, etc.) are now automatically uploaded and served when you deploy, providing complete asset coverage

 ## Web editor and deployment enhancements

 ## Performance and build optimizations

 - MDX transpilation now happens at deployment time instead of on every page load in uncached NextJS serverless environments, improving time to first byte for uncached pages.
 - Content-based hashing prevents re-transpilation when MDX hasn't changed, reducing update workflow times by ~50% for customers with large page counts (deployments over 5 minutes should be roughly halved)
 - Preview deployment viewing in the dashboard is now faster with added database indexes and query parallelization in our backend
 - Reduced page size by eliminating duplicate `navigation` data in each page's `rsc` payload—performance gains most noticeable with high page counts or complex navigation structures
 - More aggressive prefetching enables instant page loads more frequently

 ## API playground and OpenAPI enhancements

 - OpenAPI to MCP conversion moved to backend, enabling hosted MCP servers to contain tools (expect clearer documentation and config options soon)
 - Added Ruby support to API playground
 - We added a feature such that you can now [specify API pages using just your docs.json](/api-playground/openapi-setup#auto-populate-api-pages) without creating any new mdx files.
 - Support for [`webhook` pages](/api-playground/openapi-setup#webhooks) in docs navigation from OpenAPI specs
 - Optimized AI model context by removing anchor link specifications from markdown links when navigating to Anthropic, OpenAI, or other providers

 - File creation/renaming now saves changes when clicking away instead of requiring Enter key press
 - Fixed branch navigation where changing URL to specific branch would redirect to last active branch instead of intended destination

 - Added [Hightouch analytics integration](/integrations/analytics/hightouch#hightouch)

  - Group-level public access: make entire page groups public via `docs.json` so you don’t need `public: true` on each page ([learn more](https://mintlify.com/docs/authentication-personalization/authentication-setup#group-level))
  - Support [`logoutURL` in OAuth configuration](https://mintlify.com/docs/authentication-personalization/authentication-setup#implementation-3) to delete upstream cookies and complete sign-out

  - Fixed a flash of a 500 error during OAuth/JWT flows before the callback
  - Auto-strip `https://` from URLs in OAuth/JWT auth configuration to prevent misconfiguration

  ## API playground enhancements

  - New [Search API endpoint](https://mintlify.com/docs/api-reference/assistant/search) so you can build agents and MCP servers on top of your docs
  - `openapi` and `asyncapi` files are now served at their specified paths (for example, `https://mydocsurl.extension/{openapi-or-file-name}.json`)
  - You can now use the [`x-mint` field in your openapi files](https://mintlify.com/docs/api-playground/openapi-setup#x-mint-extension) to override generated fields, customize preface content, or change endpoint URLs in code samples
  - [`x-mcp` is now `x-mint.mcp`](https://mintlify.com/docs/api-playground/openapi-setup#mcp) in OpenAPI configurations to control which routes are exposed as MCP tools

  ## Assistant updates

  - Fixed an issue where the action menu (containing options like copy and thumbs up) for older messages disappeared when new ones streamed in
  - Fixed accessibility of nested `/mcp/...` pages after the [hosted MCP servers release](https://mintlify.com/docs/ai/model-context-protocol#accessing-your-mcp-server) from last week

  ## Performance and reliability

  - All image and video assets present in your docs repo are now served at the appropriate path on your domain. For example, if you have `/assets/marketing/my-logo.png` in your repo, it will be available at `https://mydocsurl.extension/assets/marketing/my-logo.png`.
  - Email field on login for the Mintlify dashboard now autofocuses so you can start typing immediately _(quality of life improvement)_

  - Added retry logic for PDF exports to improve reliability
  - Fixed cookie consent popup reappearing after acceptance or dismissal—first selection is now respected
  - Fixed copying a page to clipboard on Safari by specifying a MIME `type` in `navigator.write`

  ## Technical improvements

  - CLI bugfixes for windows and pnpm, plus CI tests to prevent regressions
  - Improved error logging output—a quality of life upgrade for our engineering team when debugging
  - Minor fixes to the broken-link CI action when `contentDirectory` files are missing
  - Fixed a regression caused by the auth-protected preview fixes from last week where the active tab was not being set correctly in the navigation UI
  - Fixed theme light background color not being applied to active tab icons
  - Fixed an issue where changing the auth type in the dashboard would update and then flip back to the previously saved type—now the new selection persists after saving
  - Internal DX improvements for enterprise customers with custom UI libraries—it's now easier for us to include your components and accommodate requests on shorter timelines
