## What's New

### MCP Server Testing

Test your MCP server integrations directly from the dashboard. Verify connectivity, validate configurations, and debug issues before deploying to production.

Upload files directly in assistant conversations to get better suggestions and more context-aware help when building tasks.

### Enhanced Assistant Buttons

Interactive buttons in assistant responses make it easier to take action on suggestions without switching contexts.

## Improvements
