Bumps open-webui/open-webui from v0.8.12 to v0.9.1.

Release notes

Sourced from open-webui/open-webui's releases.

v0.9.1

Fixed

• 🐛 Missing aiosqlite dependency. Fixed a startup crash (ModuleNotFoundError: No module named 'aiosqlite') when installing Open WebUI via pip or uv by adding the missing aiosqlite package to pyproject.toml. The dependency was listed in requirements.txt but not in the published package metadata, so it was not installed automatically. #23916
• 🐛 Missing asyncpg dependency. Added the missing asyncpg package to pyproject.toml to prevent the same startup crash for PostgreSQL users. Like aiosqlite, it was present in requirements.txt but absent from the published package dependencies.

v0.9.0

[!CAUTION] ⚠️ Database Migrations: This release includes database schema changes; we strongly recommend backing up your database and all associated data before upgrading in production environments. If you are running a multi-worker, multi-server, or load-balanced deployment, all instances must be updated simultaneously, rolling updates are not supported and will cause application failures due to schema incompatibility.

Added

• 🖥️ Official Open WebUI Desktop App. Open WebUI is now available as a native desktop app for Mac, Windows, and Linux. No Docker, no terminal, no setup. Runs Open WebUI locally without any server setup, or connects to your existing remote Open WebUI instances. Switch between multiple servers instantly from the sidebar. Comes with a system-wide floating chat bar (Shift+Cmd+I on macOS, Shift+Ctrl+I on Windows/Linux), system-wide push-to-talk, offline support after first launch, automatic updates, and zero telemetry. #8262, Desktop
• 🤖 Scheduled chat automations. You can now schedule the AI to run tasks automatically on a recurring basis: daily digests, periodic reports, anything you'd otherwise need to remember to ask for. Create and manage automations from the Automations page or directly in chat, with full run history and manual trigger controls. #23303, Commit, Commit, Commit, Commit
• 🧰 Automation tools in chat. Built-in chat tools can now create, update, list, pause, and delete scheduled automations directly in conversation when automation access is enabled. Commit
• ⏱️ Automation scheduling limits. Administrators can now set "AUTOMATION_MAX_COUNT" and "AUTOMATION_MIN_INTERVAL" to limit how many automations each non-admin user can create and prevent overly frequent schedules that could overload the system. Commit
• 📋 Task management tool. AI models can now create, update, and track tasks within a chat conversation, breaking down complex requests into manageable steps with real-time status updates. Commit
• 🗓️ Calendar workspace and event management. Open WebUI now has a full Calendar workspace. Create and manage events, set up recurring schedules, get reminders via in-app toasts or browser notifications, and see your scheduled automations alongside your calendar. #23880
• 🔔 Calendar reminders and alerts. Calendar events now support reminder options from no alert up to one hour before start time, with upcoming alerts delivered through in-app toasts, browser notifications, and optional webhooks while avoiding duplicate sends. Commit
• ⚙️ Scheduler reminder configuration. Administrators can now configure calendar reminder processing with "SCHEDULER_POLL_INTERVAL" and "CALENDAR_ALERT_LOOKAHEAD_MINUTES", while existing "AUTOMATION_POLL_INTERVAL" setups continue to work as a legacy fallback. Commit
• ☁️ Azure responses support. Azure OpenAI connections now support the newer "/openai/v1" format, enabling chat, responses, and proxy calls to work correctly with that endpoint style. #23484
• 🤖 Ollama responses support. The Ollama proxy now supports the Responses API, letting clients use "/v1/responses" directly with Ollama-hosted models through Open WebUI. #23483
• 🧩 Responses tool output rendering. Built-in tool outputs in Responses API flows now render more consistently so downstream chat output is easier to interpret. Commit, #23482
• 🔎 Responses citation visibility. Responses API flows now emit citation sources more consistently, making linked references easier to preserve and display in chat output. Commit, #23774
• 📎 Attach previously uploaded files. The chat input menu now includes a Files tab for browsing and attaching previously uploaded files, eliminating the need to re-upload files you have already shared. Commit
• 🧷 Default model terminal selection. Workspace model editors can now preselect an Open Terminal connection, so new chats automatically start with the model’s configured terminal ready to use. Commit, #23605
• 🎙️ Mistral TTS support. Mistral can now be used as a text-to-speech provider, with admin settings for the API key, base URL, voices, and model selection. Commit
• 🎧 STT preprocessing bypass option. Administrators can now enable "AUDIO_STT_SKIP_PREPROCESSING" to send audio files directly to the speech-to-text backend, reducing memory and CPU consumption during large uploads for better transcription performance and stability on constrained deployments. #23661
• 🗑️ Admin model deletion. Administrators can now delete Ollama models directly from the model selector menu, making it easier to clean up unused or unwanted models. Commit
• 🔌 Backend outlet filters for local and persisted chats. Pipeline and function outlet filters now run reliably in backend completion flows for persisted chats and temporary local chats. #3237, Commit
• 🎨 Emoji shortcode support. Typing a colon in the chat input now opens an emoji suggestion menu, making it easier to insert emojis using shortcodes like 👋. Commit
• 📌 Recently used emojis. The emoji picker now shows your most recently used emojis at the top, making it faster to find emojis you use often. Commit
• 👆 Swipe to reply on mobile. Swiping right on a message now triggers a reply, making it easier to respond on touch devices with a natural gesture. Commit
• 📱 Screen-awake voice recording. Voice recording now keeps the screen awake during active dictation and safely re-acquires wake lock after visibility changes, helping prevent long transcriptions from being cut off on mobile devices. #23145
• 🔔 Unread chat indicators. Sidebar chats now show unread status and are marked as read when opened, making it easier to spot conversations with new activity. Commit
• 🔌 WebSocket reconnect status feedback. Open WebUI now warns when the real-time connection drops and confirms when it reconnects, while avoiding a reconnect message on the initial page load. Commit
• 📍 Pinned notes in sidebar. Notes can now be pinned to the sidebar for quick access, and you can also create a new note directly from the pinned notes section. Commit, Commit
• 🗂️ Model selector focus. The model selector now resets its search only when it opens, making the popup feel more predictable while still focusing the search field automatically. Commit
• 🗂️ Model selector layout. The model selector now behaves more predictably as a custom popup, and the completions playground uses a simpler model picker for easier selection. Commit
• 🎚️ Active filter valve shortcut. Active filter badges now expose valve configuration directly in the chat input area, so filter tuning is faster during conversations. Commit, #23811, #23813
• 🎨 Theme updates. Other windows can now update the app theme directly, keeping the interface in sync when theme changes are triggered externally. Commit
• 🚀 Async performance and responsiveness improvements. The core backend database and request paths now run asynchronously across the application, massively improving responsiveness and performance under concurrent load and reducing request blocking during heavy activity. Commit, Commit
• ⚡ Drawer performance and memory optimization. Drawer interactions now stay smoother over long sessions by removing stale keyboard listeners on teardown, which reduces memory growth and avoids accumulated event handling overhead. #23724
• 🚀 Chat history memory culling. Long conversations now stay responsive no matter how many messages they contain. Off-screen messages are unloaded automatically and reloaded as you scroll, keeping memory usage low and the UI smooth on both desktop and mobile. #23067, Commit, Commit
• 🧵 Async file and knowledge processing performance. File processing, knowledge reindexing, and channel message helper paths now consistently await async operations, preventing skipped processing steps and improving reliability and performance of indexing and tool responses. Commit
• 🚀 Persistent chat payload efficiency. Persisted chats now use server-side history loading instead of repeatedly resending full message payloads, improving multimodal performance and reducing stale-history overwrite risk across devices. #19064, Commit, Commit
• 🧵 Non-blocking file storage operations. Uploading, reading, transcribing, and deleting files now offloads storage I/O to background threads, keeping the application responsive during file-heavy workflows. Commit
• 🏎️ Streaming response performance. Streaming responses now process each output line in a single step instead of two separate yields, reducing async overhead and improving responsiveness during long-running generations. #23266
