Product updates

​

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

• Fixed branch creation workflow in web editor to correctly navigate to and stay on newly created branches
• Enhanced merge conflict dialog with proper escape functionality, no more page reloads required to dismiss conflicts
• Optimized update workflow performance by cache-invalidating only changed pages during partial updates, reducing deployment times

​

Authentication and navigation improvements

• New support for authentication on custom subdirectories, if you serve docs at https://yourdomain.com/docs, authentication now works seamlessly
• Fixed sidebar display bug that incorrectly showed when only one link was configured
• Comprehensive mobile navigation overhaul: centered buttons with proper margin/padding, improved spacing in dropdown menus, removed unnecessary dividers and margins for empty sections, and fixed Maple theme gap/padding issues

​

Component and styling fixes

• Resolved <h1-6> tag conversion issue that was incorrectly transforming them into Heading components and disrupting custom styling
• One-click assistant configuration toggle added to dashboard for easier management

​

Technical improvements and reliability

• Enhanced logging system for update workflows enabling faster debugging and issue resolution
• Fixed GitHub rate limiting for customers with 10+ OpenAPI/AsyncAPI specs by switching from individual file fetching to repository cloning
• Improved assistant reliability with backup LLM support, enhanced rate limit error handling, and more robust search tool functionality

​

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 without creating any new mdx files.
• Support for webhook pages 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

​

Web editor improvements

• 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
• Properly URL encode branch titles containing / to prevent navigation breakage
• Fixed Ctrl+K link shortcut in monorepo dashboard Editor that was prepending docs repo path and creating broken links

​

Analytics and LLM integrations

• Custom llms.txt and llms-full.txt support—add to docs repo root to serve at /llms.txt and /llms-full.txt endpoints for LLM customization
• Added Hightouch analytics integration
• Enhanced context menu analytics tracking (dashboard viewing coming soon)
• Added e2e tests for llms.txt and llms-full.txt to ensure correct serving

​

• Corrected VSCode to VS Code in contextual menu when enabled
• Fixed headings within custom components appearing in table of contents alongside semantic headings

​

Bug fixes and reliability

​

Technical improvements

• Added visual tests to CI pipeline for earlier regression detection

​

Authentication improvements

• 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 so you can build agents and MCP servers on top of your docs

• You can now use the x-mint field in your openapi files to override generated fields, customize preface content, or change endpoint URLs in code samples
• x-mcp is now x-mint.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 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)
