Open WebUI Files

Added

• 🔐 Custom OIDC logout endpoint. Administrators can now configure a custom OpenID Connect logout URL via OPENID_END_SESSION_ENDPOINT, enabling logout functionality for OIDC providers that require custom endpoints like AWS Cognito. Commit
• 🗄️ MariaDB Vector community support. Added MariaDB Vector as a new vector database backend, enabling deployments with VECTOR_DB=mariadb-vector; supports cosine and euclidean distance strategies with configurable HNSW indexing. #21931
• 📝 Task message truncation. Chat messages sent to task models for title and tag generation can now be truncated using a filter in the prompt template, reducing token usage and processing time for long conversations. #21499
• 🔄 General improvements. Various improvements were implemented across the application to enhance performance, stability, and security.
• 🌐 Translations for Portuguese (Brazil), Spanish, and Malay were enhanced and expanded.

Fixed

• 🔗 Pipeline filter HTTP errors. Fixed a bug where HTTP errors in pipeline inlet/outlet filters would silently corrupt the user's chat payload; errors are now properly raised before parsing the response. #22445
• 📚 Knowledge file embedding updates. Fixed a bug where updating knowledge files left old embeddings in the database, causing search results to include duplicate and stale data. #20558
• 📁 Files list stability. Fixed the files list ordering to use created_at with id as secondary sort, ensuring consistent ordering and preventing page crashes when managing many files. #21879
• 📨 Teams webhook crash. Fixed a TypeError crash in the Teams webhook handler when user data is missing from the event payload. #22444
• 🛠️ Process shutdown handling. Fixed bare except clauses in the main process that prevented clean shutdown; replaced with proper exception handling. #22423
• 🐳 Docker deployment startup. Docker deployments now start correctly; the missing OpenTelemetry system metrics dependency was added. #22447, #22401
• 🛠️ Tool access for non-admin users. Fixed a NameError that prevented non-admin users from viewing tools; the missing has_access function is now properly imported. #22393
• 🔐 OAuth error handling. Fixed a bug where bare except clauses silently caught SystemExit and KeyboardInterrupt, preventing clean process shutdown during OAuth authentication. #22420
• 🛠️ Exception error messages. Fixed three locations where incorrect exception raising caused confusing TypeError messages instead of proper error descriptions, making debugging much easier. #22446
• 📄 YAML file processing. Fixed an error when uploading YAML files with Docling enabled; YAML and YML files are now properly recognized as text files and processed correctly. #22399, #22263
• 📅 Time range month names. Fixed month names in time range labels appearing in the wrong language when OS regional settings differ from browser language; month names now consistently display in English. #22454
• 🔐 OAuth error URL encoding. Fixed OAuth error messages with special characters causing malformed redirect URLs; error messages are now properly URL-encoded. #22415
• 🛠️ Internal tool method filtering. Tools no longer expose internal methods starting with underscore to the LLM, reducing clutter and improving accuracy. #22408
• 🔊 Azure TTS locale extraction. Fixed Azure text-to-speech using incomplete locale codes in SSML; now correctly uses full locale like "en-US" instead of just "en". #22443
• 🎤 Azure speech transcription errors. Improved Azure AI Speech error handling to display user-friendly messages instead of generic connection errors; empty transcripts, no language identified, and other Azure-specific errors now show clear descriptions. #20485
• 📊 Analytics group filtering. Fixed token usage analytics not being filtered by user group; the query now properly respects group filters like other analytics metrics. #22167
• 🔍 Web search favicon fallback. Fixed web search sources showing broken image icons when favicons couldn't be loaded from external sources; now falls back to the default Open WebUI favicon. #21897
• 🔄 Custom model fallback. Fixed custom model fallback not working when the base model is unavailable; the base model ID is now correctly retrieved from model info instead of empty params. #22456
• 🖼️ Pending message image display. Fixed images in queued messages appearing blank; image thumbnails are now properly displayed in the pending message queue. #22256
• 🛠️ File metadata sanitization. Fixed file uploads failing with JSON serialization errors when metadata contained non-serializable objects like callable functions; metadata is now sanitized before database insertion. #20561
