## Executive Summary (TL;DR)
Open WebUI v0.8.3. Source highlight: [0.8.3] - 2026-02-17

## New Features
- ✏️ **Model edit shortcut.** Users can now edit models directly from the model selector dropdown menu, making it faster to modify model settings without navigating to separate admin or workspace pages. Commit
- 🎨 **Image edit API background support.** The image edit API now supports the background parameter for OpenAI's gpt-image-1 model, enabling background transparency control ("transparent", "opaque", "auto") when the feature is exposed in the UI. #21459
- ⚡ **Faster model filtering.** Model access control filtering no longer makes a redundant database query to re-fetch model info that is already available in memory, reducing latency when loading model lists for non-admin users. Commit
- 🔧 **Tool call display improvements.** Tool call results now display arguments in a cleaner key-value format instead of raw JSON, with a responsive layout that shows only the tool name on narrow screens and the full label on wider screens, preventing text wrapping to multiple lines. Commit
- 🔄 **General improvements.** Various improvements were implemented across the application to enhance performance, stability, and security.
- 🌐 Translations for Portuguese (Brazil), Simplified Chinese, and Traditional Chinese were enhanced and expanded.

## Bug Fixes
- 📧 **USER_EMAIL variable fix.** The {{USER_EMAIL}} template variable now correctly returns the user's email address instead of "Unknown" in prompts. #21479, #21465
- 🖼️ **Image and file attachment handling fixes.** Uploaded images are now correctly sent to vision-enabled models, and file attachments now work even when no user text is entered alongside a system prompt. This fixes two issues where the backend was not properly processing file attachments: images weren't converted to the expected format for API requests, and file context was dropped when the user sent only a file without accompanying text. Commit, #21477, #21457
- 🛡️ **Missing function error handling.** Models that reference deleted functions no longer cause the entire /api/models endpoint to crash; instead, the missing functions are skipped and logged, allowing the rest of the models to load successfully. #21476, #21464
- 🚀 **Startup model pre-fetch error handling.** If model pre-fetching fails during app startup, the application now logs a warning and continues instead of crashing entirely. Commit
- ⚙️ **Function module loading error handling.** Function modules that fail to load during startup or model processing are now caught and logged, preventing crashes when models reference functions with loading errors. Commit
- 🗄️ **PostgreSQL group query fix.** The '/api/v1/groups/' endpoint no longer fails with a GROUP BY error when using PostgreSQL; member counts are now calculated using correlated subqueries for better database compatibility. #21458, #21467
