+## External sources for AI assistant
+
+- **Major feature**: Enrich the assistant with more context by configuring external sources

+- This feature is currently in beta. For access, please contact our team or reach out to [email protected]
+
+## Fallback support email for assistant
+
+- Our assistant is optimized to reduce hallucinations and lets users know when it can't find info in the docs
+- When that happens, now you can [set a support email](https://www.mintlify.com/docs/guides/assistant#response-handling) to send users in the right direction
+
+## Answer questions directly in Slack with AI
+
+- Use an AI chatbot as your first line of defense in a Slack community
+- The Mintlify Slack app pulls directly from your documentation so you can answer product questions instantly
+- Works in DMs, @ mentions, or dedicated channels. [One click to install](https://www.mintlify.com/docs/ai/slack-app#slack-appan)
+
+## Customize auto-generated OpenAPI pages
+
+- The new [x-mint extension](https://www.mintlify.com/docs/api-playground/openapi-setup#x-mint-extension) gives more granular control over displaying your auto-generated API documentation
+- You can override default metadata, add content, or change the URL of the endpoint
+
+## Additional improvements
+
+- Auto-updating CLI for improved development experience
+- Faster page loads across all documentation sites
+- Optimized images for better performance

 - Fixed a bug where Google was indexing raw `*.md` files because they were missing a `x-robots-tag noindex` header

 ## 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

 - File creation/renaming now saves changes when clicking away instead of requiring Enter key press
