This caused all HTTP and WebSocket connections to stall for every user on the instance during STT processing. - Add asyncio import - Use async UploadFile.read() instead of synchronous file.file.read() - Offload the blocking transcribe() call via asyncio.to_thread() Closes #24169 * refac * fix: open file content in new window when clicking file name in FileItemModal (#24125) Previously, clicking the file name link did not open the file content because the condition checked `!isPDF && item.url`, which failed for `type === 'file'` items that use an ID-based URL path. Update the condition to trigger on `item.type === 'file' || item.url`, and resolve the correct URL by extracting `fileId` from `item.id` or `item.tempId` instead of using `item.url` directly as the file identifier. * refac * refac * refac * refac * refac * refac * refac * refac * refac * Refactor file processing to use asyncio for transcribing, improving concurrency.

This prevents Out-of-Memory crashes for users with large chat histories. Backend: Added async generator that paginates through chats with short-lived DB sessions per batch (critical for SQLite lock release). Frontend: Updated getAllChats to consume the NDJSON stream via ReadableStream reader, accumulating results for the export file.

With 600+ prompts this issued ~600 extra round-trips per request and explained the multi-second delay reported in the GET /api/v1/prompts and /api/v1/prompts/tags endpoints for non-admin users. Push the access check into a single SQL query via the existing AccessGrants.has_permission_filter (EXISTS subquery), so only accessible rows come back from the DB. Users and access grants for the surviving rows are still batch-fetched, no N+1 anywhere on this path. Co-authored-by: Claude <noreply@anthropic.com> * refac * refac * Update catalan translation.json (#24174) * perf(prompts): make /tags fetch only the tags column with SQL access filter (#24287) Non-admin GET /api/v1/prompts/tags went through get_prompts_by_user_id, which loaded every active prompt with its full content/data/meta plus owner records and all access grants, then ran one has_access query per prompt that wasn't owned by the caller - all so the endpoint could collapse the result to a sorted tag list. With 600 prompts this took several seconds while the admin path (a single SELECT) returned in <1s. Add Prompts.get_tags_by_user_id which selects only the tags column and applies the same EXISTS-based access filter used by /list. Also tighten the admin get_tags to project just the tags column instead of full rows. The endpoint is now one DB query (plus one for groups), no row hydration, no N+1.

The MCPClient's exit_stack contains anyio resources (streamable_http transport) that use anyio cancel scopes. When exited from a different task, anyio raises 'Attempted to exit a cancel scope that isn't the current task's current cancel scope' as a BaseException. This BaseException propagates through the finally block, discards the completed response return value, and surfaces as a 500 Internal Server Error / 'No response returned.' - silently swallowing successful MCP tool calls and blocking the chat endpoint. Fix: call client.disconnect() directly in a simple loop. MCPClient.disconnect() already catches BaseException internally (see prior commit), so no wrapper is needed.

+- 🔇 **Voice Mode mute control.** Voice Mode now includes a dedicated mute toggle with an "M" shortcut and auto-unmute after assistant playback, so you can prevent accidental interruptions from background noise without leaving the call overlay. [Commit](https://github.com/open-webui/open-webui/commit/072d2000f35a9f7b96342fa9bb28f925a92e7b4c), [#23832](https://github.com/open-webui/open-webui/issues/23832)
+- 🚀 **Faster prompt list loading.** Prompt and prompt-tag pages now load much faster for non-admin users, even with large prompt libraries, because accessible prompts are filtered efficiently in a single database query. [#24288](https://github.com/open-webui/open-webui/pull/24288), [#24258](https://github.com/open-webui/open-webui/discussions/24258)
+- ⚡ **Faster chat history loading.** Chat history maps now load from normalized message records when available, reducing overhead for large conversations while preserving fallback behavior for legacy chats. [Commit](https://github.com/open-webui/open-webui/commit/485d689cfd1ef8b9e7f77cd7b535b8b8747dff1f), [#23159](https://github.com/open-webui/open-webui/pull/23159)
+- 🗑️ **Delete from conversation menu.** You can now delete the current conversation directly from the chat menu with a confirmation step, so cleanup is faster without searching through the full chat list. [Commit](https://github.com/open-webui/open-webui/commit/ef6d4f2d6c4b79c7e12e864a4fcb6a57ee84e5d4), [#24329](https://github.com/open-webui/open-webui/issues/24329)
+- ⬆️ **Scroll to Top shortcut.** Long conversations now include a Scroll to Top action in the chat menu when you are away from the top, making it much faster to jump back to the beginning of a chat. [Commit](https://github.com/open-webui/open-webui/commit/cdfcbc4af6e9aec835b88dc1806a2a46711e6947), [#24133](https://github.com/open-webui/open-webui/issues/24133)

[Commit](https://github.com/open-webui/open-webui/commit/4fe2de78643c2213652190d2820f4e8d9f4f89cc)
+- ⚡ **Health check responsiveness.** Health and readiness probes now avoid blocking database calls and skip sync session commit handling on probe paths, improving responsiveness and reducing false unready transitions during database pressure. [#24380](https://github.com/open-webui/open-webui/pull/24380), [#24384](https://github.com/open-webui/open-webui/pull/24384)
+- 🎛️ **Playground controls panel.** The Playground now includes a dedicated Controls toggle so you can adjust parameters like temperature and related settings per chat run without changing model-level defaults. [Commit](https://github.com/open-webui/open-webui/commit/c6763521c00f042a28829e33fb6f1b7355054046), [#24103](https://github.com/open-webui/open-webui/issues/24103)
+- 🎙️ **STT file extension controls.** Administrators can now configure which audio file extensions are accepted for speech-to-text uploads, helping enforce safer and more predictable upload policies. [Commit](https://github.com/open-webui/open-webui/commit/4754ece4a2de5bba85a1d53af2dc8d24fdfb58be)
+- 📷 **Remembered call camera selection.** Voice call overlay now remembers your last selected camera and restores it automatically when available, so you do not need to reselect it every time you start voice mode. [Commit](https://github.com/open-webui/open-webui/commit/5c3edc2539ac4d92c4cc2d37079549995203238a), [#24416](https://github.com/open-webui/open-webui/issues/24416)
+- 👥 **User group prompt variable.** System and template prompts now support the "{{USER_GROUPS}}" variable, which expands to the user’s group memberships so prompts can adapt to role- or access-based context automatically. [Commit](https://github.com/open-webui/open-webui/commit/c1202a23277abb8e7080271a929dcc9d29b67e66), [#24462](https://github.com/open-webui/open-webui/issues/24462)

+- 🔐 **Profile image forwarding control.** Administrators can now disable external profile image URL forwarding with the "ENABLE_PROFILE_IMAGE_URL_FORWARDING" setting to prevent browser metadata leaks to third-party servers. [#24420](https://github.com/open-webui/open-webui/pull/24420)
+- 🏷️ **Dynamic header template variables.** Administrators can now use chat, message, and user template variables in custom connection and tool server headers so each request can carry per-conversation context automatically. [Commit](https://github.com/open-webui/open-webui/commit/9907c0a25ae830d134af70022238715f834d20c6), [#24164](https://github.com/open-webui/open-webui/pull/24164)
+- 🛂 **MCP OAuth server URL setting.** Static OAuth tool server setups can now define a separate OAuth server URL, making discovery and client registration work when authentication endpoints are hosted separately from the tool server URL. [Commit](https://github.com/open-webui/open-webui/commit/9907c0a25ae830d134af70022238715f834d20c6), [#24164](https://github.com/open-webui/open-webui/pull/24164), [#24216](https://github.com/open-webui/open-webui/issues/24216)
+- ⚡ **Faster memory query performance.** Per-user memory lookups and deletions now run much faster at scale because the memory user filter is indexed for existing and new installations. [Commit](https://github.com/open-webui/open-webui/commit/38a382ef888685650135d61dcc8ec0e29eb65573), [#23836](https://github.com/open-webui/open-webui/pull/23836)
+- 🚀 **Smarter function dependency installs.** Function dependencies are now skipped when they were already preinstalled and unchanged, reducing first-load delays and repeated package installation churn after startup. [Commit](https://github.com/open-webui/open-webui/commit/ae43562b869b24699408e5ab107261a0a8bdb4bc), [#24166](https://github.com/open-webui/open-webui/pull/24166)
+- 🔎 **Brave LLM Context web search.** Administrators can now choose Brave LLM Context as a web search provider to retrieve richer grounded passages with a configurable context token budget. [Commit](https://github.com/open-webui/open-webui/commit/6700f7bb72d14a3f8dbb72dfa064cae3b3dc29ac), [#24120](https://github.com/open-webui/open-webui/issues/24120)
+- 🗂️ **Open Terminal date sorting.** Open Terminal now includes sort controls for name and date, with directory-first ordering and modified-time visibility to make file browsing faster. [Commit](https://github.com/open-webui/open-webui/commit/6bdc2ffa79d72daf78981209c9c5292c697cbfe5), [#24425](https://github.com/open-webui/open-webui/issues/24425)
+- 🎤 **Voice mode prompt toggle.** Administrators can now explicitly enable or disable the Voice Mode custom prompt behavior from Interface settings, giving finer control over how voice replies are guided. [Commit](https://github.com/open-webui/open-webui/commit/17893038869e3a763a8b34457f723b9666804e27)
+- 🧮 **LaTeX copy shortcut.** You can now click rendered LaTeX expressions to copy the raw formula to your clipboard, making it easier to reuse equations outside chat. [Commit](https://github.com/open-webui/open-webui/commit/064fdecb675c176a04b024c16ce179f4dda45236), [#24244](https://github.com/open-webui/open-webui/pull/24244)
+- ✨ **Smoother rich text editing.** The message composer now defers formatting toolbar refresh work to the next animation frame, reducing typing jank while formatting controls stay accurate. [Commit](https://github.com/open-webui/open-webui/commit/794b97025d4c56f91d49c9d1ec4775d2ea07b53a), [#24013](https://github.com/open-webui/open-webui/pull/24013)
+- 🖼️ **Arena model profile images.** Arena models can now reliably display configured profile images instead of falling back to the default icon. [Commit](https://github.com/open-webui/open-webui/commit/1dee67b64d0b34e70bac949682b216c0aaec8152), [#24412](https://github.com/open-webui/open-webui/issues/24412)
+- 🔄 **Replaceable tool embed updates.** Pipes and Tools can now overwrite previously emitted rich-UI embeds in-place by passing a `replace` flag on the `embeds` event, enabling live dashboards and progress panels that update without stacking duplicate entries.
+- ✏️ **Assistant response editing and continuation.** You can now edit and restructure assistant output items — including reasoning blocks, tool calls, and text content — from a dedicated editor view, and continue generating from the edited state so the model receives full prior context.
+- 🔄 **General improvements.** Various improvements were implemented across the application to enhance performance, stability, and security.
+- 🌐 **Translation updates.** Translations for Chinese, Catalan, Filipino, and Korean were enhanced and expanded.
+
+### Fixed
+
+- 🧵 **Background code execution reliability.** Code execution no longer hangs indefinitely when you switch conversations or browser tabs during a run, and disconnected or inactive sessions now fail with a clear timeout error instead of endless processing. [Commit](https://github.com/open-webui/open-webui/commit/552bbcecfae5ae273ab98e2ce3e540d0771aa964), [#24089](https://github.com/open-webui/open-webui/issues/24089)
+- 🎙️ **Voice recording MIME fallback support.** Voice recording now tries a broader set of browser-supported audio formats and resets halted audio playback cleanly, improving microphone capture reliability in browsers where recording previously failed to start. [Commit](https://github.com/open-webui/open-webui/commit/8ffc3d746f20007e9eb4e3ae4f152f383bc371e1), [#24162](https://github.com/open-webui/open-webui/issues/24162)
+- 🧠 **Direct-connection task generation reliability.** Title, tags, follow-up, emoji, query, and related task-generation endpoints now work correctly when chats use direct-connection models instead of failing with model-not-found errors. [Commit](https://github.com/open-webui/open-webui/commit/1b4cd705d0b9a51a5e3a7851ec012fb3141eb0a9), [Commit](https://github.com/open-webui/open-webui/commit/005df577fec16733a64edbec8a1b46f42f4e9a43), [#24092](https://github.com/open-webui/open-webui/issues/24092)
+- 🔧 **Parameterized URL tool readiness.** New chats now wait for model defaults to finish applying before auto-submit, preventing early requests that can miss configured external tools.

+
+### Changed
+
+- ⚠️ **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.
+- 🚪 **Signout request method.** The signout endpoint now requires POST instead of GET, so custom clients and integrations must update logout calls accordingly. [#24420](https://github.com/open-webui/open-webui/pull/24420)
+
+## [0.9.2] - 2026-04-24
+
+### Added
+
+- 🧠 **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](https://github.com/open-webui/open-webui/pull/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](https://github.com/open-webui/open-webui/pull/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](https://github.com/open-webui/open-webui/pull/23918)
+- ⚡ **Model list performance.** Model list API responses now strip base64 profile image data from paginated results, and model tags are fetched via a dedicated efficient query instead of loading all models. This significantly reduces payload sizes and improves workspace Models page responsiveness.
+- ⚡ **Model avatar cache reuse.** Default model profile images now redirect to a shared static path instead of reading files from disk per-request, reducing repeated I/O and improving loading efficiency when multiple models use the fallback icon. [#24015](https://github.com/open-webui/open-webui/pull/24015)
+- 🚀 **Faster splash image loading.** Splash screen images are now prioritized earlier during page load with preload links, improving first-load LCP behavior and reducing delayed image discovery. [#24011](https://github.com/open-webui/open-webui/pull/24011)

+- 🔄 **General improvements.** Various improvements were implemented across the application to enhance performance, stability, and security.
+- 🌐 **Translation updates.** Translations for Finnish, Korean, Portuguese (Brazil), and Dutch were enhanced and expanded.
+
+### Fixed
+
+- 🔧 **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](https://github.com/open-webui/open-webui/pull/23979)
+- ✍️ **Rich text extension conflicts.** Rich text editing no longer triggers duplicate extension conflicts for lists and code blocks, improving editor stability. [#24009](https://github.com/open-webui/open-webui/pull/24009)
+- 🔇 **Fetch URL null content guard.** The `fetch_url` built-in tool now safely handles `None` content returned by web loaders instead of crashing with a `TypeError`.
+- 🌐 **OAuth discovery fallback.** OAuth protected resource discovery now falls back to well-known RFC 9728 URIs when the `WWW-Authenticate` header doesn't contain a `resource_metadata` link, improving compatibility with more MCP server implementations.
+- 🔐 **Session token resolution.** Session user endpoints now gracefully handle missing `Authorization` headers by falling back to cookie and request state tokens, preventing errors when used behind forward-auth proxies.
+- 🚫 **Direct API error responses.** Chat completion requests without a WebSocket channel (direct API calls) now return proper HTTP error responses instead of silently returning null on failure.
+- 📡 **Cancelled response stream cleanup.** Cancelled chat generation now explicitly closes the upstream response body iterator, preventing orphaned async generators from spinning in anyio internals.
+- 🔒 **Model profile image path safety.** Model profile image endpoints now validate and sanitize static asset redirect paths, preventing path traversal through encoded dots or malicious URL patterns.
+- 📊 **RAG template validation UI.** The Documents settings page now displays a warning when RAG templates contain multiple `[context]` or `{{CONTEXT}}` placeholders, helping administrators avoid accidental redundant context injection.
+- 🧩 **Automation model detection.** The `create_automation` tool now correctly detects the current model ID even when `model_id` is not yet set in metadata, falling back to the model dict.
+- 🔄 **MCP resource content handling.** MCP tool results with the `resource` content type are now correctly detected and their `resource.text` payload is extracted, instead of being silently ignored.
