## Executive Summary (TL;DR)
Open WebUI v0.9.2. Source highlight: 🧠 **PaddleOCR-vl document extraction.** Administrators can now use PaddleOCR-vl as a content extraction engine for document processing, with configurable API URL and token settings in document retrieval configuration. #23945

## New Features
- 🧠 **PaddleOCR-vl document extraction.** Administrators can now use PaddleOCR-vl as a content extraction engine for document processing, with configurable API URL and token settings in document retrieval configuration. #23945
- 🔥 **Firecrawl v2 API.** Firecrawl web loading now uses the v2 API directly with proper retry logic, exponential backoff on rate limits, and configurable timeout handling, improving reliability for both cloud and self-hosted Firecrawl setups. #23934
- ⏰ **Calendar event reminder customization.** Calendar events now support a configurable `reminder_minutes` parameter, allowing models to set custom reminder durations instead of the default 10-minute notification.
- 🔑 **Custom API key header.** Administrators can now configure a custom header name for API key authentication via the `CUSTOM_API_KEY_HEADER` environment variable, enabling compatibility with reverse proxies that use the `Authorization` header for their own authentication.
- 🔌 **OAuth session disconnection.** Users can now disconnect OAuth sessions for specific providers (e.g., MCP connections) through a new API endpoint, enabling cleaner re-authentication workflows.
- 📚 **Source overflow indicator.** The Sources button now shows a +N badge when more than three sources are available, so hidden sources are clearly indicated in chat responses. #23918

## Improvements
- 🖥️ **Windows startup script.** The Windows startup batch script has been updated for improved compatibility.

## Bug Fixes
- 🔧 **MCP task cancellation stability.** Interrupted MCP tool calls no longer cause CPU spikes or runaway cleanup behavior. MCP client disconnection now runs in the same asyncio task as connection, respecting cancel scope constraints, and chat-active events are properly shielded during cancellation.
- 🧠 **Persistent chat skill injection.** Skills mentioned in persisted chats now inject into the system prompt reliably. Skill ID extraction from `<$skillId|label>` message tags is now handled server-side, and tags are stripped before messages reach the model.
- 🗄️ **Async database driver migration.** The async database backend now uses psycopg (v3) instead of asyncpg, eliminating brittle SSL parameter translation and supporting native libpq connection strings including `sslmode`, `options`, and `target_session_attrs` without any stripping or conversion.
- 🐳 **Docker ARM64 reliability.** Docker images built for arm64 via QEMU cross-compilation no longer produce 0-byte corrupted Python dependencies. `UV_LINK_MODE=copy` is now set in the Dockerfile to force reliable file installation.
- 🛠️ **Throttle request handling.** Request handling no longer fails when user activity status updates are throttled with a non-zero interval. #23979
- ✍️ **Rich text extension conflicts.** Rich text editing no longer triggers duplicate extension conflicts for lists and code blocks, improving editor stability. #24009
