+## [0.8.3] - 2026-02-17
+
+### Added
+
+- ✏️ **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](https://github.com/open-webui/open-webui/commit/519ff40cb69cdc1d215cee369e9db70ff7438153)
+- 🎨 **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](https://github.com/open-webui/open-webui/pull/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](https://github.com/open-webui/open-webui/commit/34cd3d79e8688f589e3dd2f03415f8a8f9a13115)
+- 🔧 **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](https://github.com/open-webui/open-webui/commit/2ce935bdb10d2b26b230cd54cb649f5c667ed96a)
+- 🔄 **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.
+
+### Fixed
+
+- 📧 **USER_EMAIL variable fix.** The {{USER_EMAIL}} template variable now correctly returns the user's email address instead of "Unknown" in prompts. [#21479](https://github.com/open-webui/open-webui/pull/21479), [#21465](https://github.com/open-webui/open-webui/issues/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](https://github.com/open-webui/open-webui/commit/f1053d94c7ef7b8b78682dd73586b65a84d202a1), [#21477](https://github.com/open-webui/open-webui/issues/21477), [#21457](https://github.com/open-webui/open-webui/issues/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](https://github.com/open-webui/open-webui/pull/21476), [#21464](https://github.com/open-webui/open-webui/issues/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](https://github.com/open-webui/open-webui/commit/337109e99ce390f55a9085d0a301853637923779)
+- ⚙️ **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](https://github.com/open-webui/open-webui/commit/15b893e651de71b033408e1b713e0b51f6829ab8)
+- 🗄️ **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](https://github.com/open-webui/open-webui/pull/21458), [#21467](https://github.com/open-webui/open-webui/issues/21467)
+
+## [0.8.2] - 2026-02-16
+
+### Added
+
+- 🧠 **Skill content handling.** User-selected skills now have their full content injected into the chat, while model-attached skills only display name and description in the available skills list. This allows users to override skill behavior while model-attached skills remain flexible. [Commit](https://github.com/open-webui/open-webui/commit/393c0071dc612c5ac982fb37dfc0288cb9911439)
+- ⚙️ **Chat toggles now control built-in tools.** Users can now disable web search, image generation, and code execution on a per-conversation basis, even when those tools are enabled as builtin tools on the model. [#20641](https://github.com/open-webui/open-webui/issues/20641), [#21318](https://github.com/open-webui/open-webui/discussions/21318), [Commit](https://github.com/open-webui/open-webui/commit/c46ef3b63bcc1e2e9adbdd18fab82c4bbe33ff6c), [Commit](https://github.com/open-webui/open-webui/commit/f1a1e64d2e9ad953b2bc2a9543e9a308b7c669c8)
+- 🖼️ **Image preview in file modal.** Images uploaded to chats can now be previewed directly in the file management modal, making it easier to identify and manage image files. [#21413](https://github.com/open-webui/open-webui/issues/21413), [Commit](https://github.com/open-webui/open-webui/commit/e1b3e7252c1896c04d498547908f0fce111434e1)
+- 🏷️ **Batch tag operations.** Tag creation, deletion, and orphan cleanup for chats now use batch database queries instead of per-tag loops, significantly reducing database round trips when updating, archiving, or deleting chats with multiple tags. [Commit](https://github.com/open-webui/open-webui/commit/c748c3ede)
+- 💨 **Faster group list loading.** Group lists and search results now load with a single database query that joins member counts, replacing the previous pattern of fetching groups first and then counting members in a separate batch query. [Commit](https://github.com/open-webui/open-webui/commit/33308022f)
+- 🔐 **Skills sharing permissions.** Administrators can now control skills sharing and public sharing permissions per-group, matching the existing capabilities for tools, knowledge, and prompts. [Commit](https://github.com/open-webui/open-webui/commit/88401e91c)
+- ⚡ **Long content truncation in preview modals.** Citation and file content modals now truncate markdown-rendered content at 10,000 characters with a "Show all" expansion button, preventing UI jank when previewing very large documents.
+- 🌐 **Translation updates.** Translations for Spanish and German were enhanced and expanded.
+
+### Fixed
+
+- 🔐 **OAuth session error handling.** Corrupted OAuth sessions are now gracefully handled and automatically cleaned up instead of causing errors. [Commit](https://github.com/open-webui/open-webui/commit/7e224e4a536b07ec008613f06592e34050e7067c)
+- 🐛 **Task model selector validation.** The task model selector in admin settings now correctly accepts models based on the new access grants system instead of rejecting all models with an incorrect error. [Commit](https://github.com/open-webui/open-webui/commit/9a2595f0706d0c9d809ae7746001cf799f98db1d)
+- 🔗 **Tool call message preservation.** Models no longer hallucinate tool outputs in multi-turn conversations because tool call history is now properly preserved instead of being merged into assistant messages. [#21098](https://github.com/open-webui/open-webui/discussions/21098), [#20600](https://github.com/open-webui/open-webui/issues/20600), [Commit](https://github.com/open-webui/open-webui/commit/f2aca781c87244cffc130aa2722e700c19a81d66)
+- 🔧 **Tool server startup initialization.** External tool servers configured via the "TOOL_SERVER_CONNECTIONS" environment variable now initialize automatically on startup, eliminating the need to manually visit the Admin Panel and save for tools to become available. This enables proper GitOps and containerized deployments. [#18140](https://github.com/open-webui/open-webui/issues/18140), [#20914](https://github.com/open-webui/open-webui/pull/20914), [Commit](https://github.com/open-webui/open-webui/commit/f20cc6d7e6da493eb75ca1618f5cbd068fa57684)
+- ♻️ **Resource handle cleanup.** File handles are now properly closed during audio transcription and pipeline uploads, preventing resource leaks that could cause system instability over time. [#21411](https://github.com/open-webui/open-webui/issues/21411)
+- ⌨️ **Strikethrough shortcut conflict fix.** Pressing Ctrl+Shift+S to toggle the sidebar no longer causes text to become struck through in the chat input, by disabling the TipTap Strike extension's default keyboard shortcut when rich text mode is off. [Commit](https://github.com/open-webui/open-webui/commit/38ae91ae2)
+- 🔧 **Tool call finish_reason fix.** API responses now correctly set finish_reason to "tool_calls" instead of "stop" when tool calls are present, fixing an issue where external API clients (such as OpenCode) would halt prematurely after tool execution when routing Ollama models through the Open WebUI API. [#20896](https://github.com/open-webui/open-webui/issues/20896)
+
+## [0.8.1] - 2026-02-14
+
+### Added
+
+- 🚀 **Channel user active status.** Checking user active status in channels is now faster thanks to optimized database queries. [Commit](https://github.com/open-webui/open-webui/commit/ca6b18ab5cb94153a9dae233f975d36bf6b19b76)
+- 🔗 **Responses API endpoint with model routing.** The OpenAI API proxy now supports a /responses endpoint that routes requests to the correct backend based on the model field in the request, instead of always using the first configured endpoint. This enables support for backends like vLLM that provide /skills and /v1/responses endpoints. [Commit](https://github.com/open-webui/open-webui/commit/abc9b63093d65f4d74342db85b7d5df1809aa0f0), [Commit](https://github.com/open-webui/open-webui/commit/79ecbfc757f0642740d0e44fab98263d84295490)
+- ⚡ **Model and prompt list optimization.** Improved performance when loading models and prompts by pre-fetching user group IDs once instead of making multiple database queries. [Commit](https://github.com/open-webui/open-webui/commit/20de5a87da0c12e4052b50887a42ddd7228c5ef5)
+- 🗄️ **Batch access control queries.** Improved performance when loading models, prompts, and knowledge bases by replacing multiple individual access checks with single batch queries, significantly reducing database load for large deployments. [Commit](https://github.com/open-webui/open-webui/commit/589c4e64c1b7bb7a7a5abc20382b92fb860e28c2)
+- 💨 **Faster user list loading.** User lists now load significantly faster by deferring profile image loading; images are fetched separately in parallel by the browser, improving caching and reducing database load. [Commit](https://github.com/open-webui/open-webui/commit/b7549d2f6ca2843661ec79a5a1e55da9e7553368)
+- 🔍 **Web search result count.** The built-in search_web tool now respects the admin-configured "Search Result Count" setting instead of always returning 5 results when using Native Function Calling mode. [#21373](https://github.com/open-webui/open-webui/pull/21373), [#21371](https://github.com/open-webui/open-webui/issues/21371)
+- 🔐 **SCIM externalId support.** SCIM-enabled deployments can now store and manage externalId for user provisioning, enabling better integration with identity providers like Microsoft Entra ID and Okta. [#21099](https://github.com/open-webui/open-webui/pull/21099), [#21280](https://github.com/open-webui/open-webui/issues/21280), [Commit](https://github.com/open-webui/open-webui/commit/d1d1efe212b16e0052359991d67fd813125077e8)
+- 🌐 **Translation updates.** Portuguese (Brazil) translations were updated.
+
+### Fixed
+
+- 🛡️ **Public sharing security fix.** Fixed a security issue where users with write access could see the Public sharing option regardless of their actual public sharing permission, and direct API calls could bypass frontend sharing restrictions. [#21358](https://github.com/open-webui/open-webui/pull/21358), [#21356](https://github.com/open-webui/open-webui/issues/21356)
+- 🔒 **Direct model access control fix.** Model access control changes now persist correctly for direct Ollama and OpenAI models that don't have database entries, and error messages display properly instead of showing "[object Object]". [Commit](https://github.com/open-webui/open-webui/commit/f027a01ab2ff3b6175af3dd13a4478c265c0544a), [#21377](https://github.com/open-webui/open-webui/issues/21377)
+- 💭 **Reasoning trace rendering performance.** Reasoning traces from models now render properly without being split into many fragments, preventing browser slowdowns during streaming responses. [#21348](https://github.com/open-webui/open-webui/issues/21348), [Commit](https://github.com/open-webui/open-webui/commit/3b61562c82448cf83710d8b6ed29b797991aa83a)
+- 🖥️ **ARM device compatibility fix.** Fixed an issue where upgrading to 0.8.0 would fail to start on ARM devices (like Raspberry Pi 4) due to torch 2.10.0 causing SIGILL errors; now pinned to torch<=2.9.1. [#21385](https://github.com/open-webui/open-webui/pull/21385), [#21349](https://github.com/open-webui/open-webui/issues/21349)
+- 🗄️ **Skills PostgreSQL compatibility fix.** Fixed a PostgreSQL compatibility issue where creating or listing skills would fail with a TypeError, while SQLite worked correctly. [#21372](https://github.com/open-webui/open-webui/pull/21372), [Commit](https://github.com/open-webui/open-webui/commit/b4c3f54f9648c4232a0fd6557703ffa66fcf4caa), [#21365](https://github.com/open-webui/open-webui/issues/21365)
+- 🗄️ **PostgreSQL analytics query fix.** Fixed an issue where retrieving chat IDs by model ID would fail on PostgreSQL due to incompatible DISTINCT ordering, while SQLite worked correctly. [#21347](https://github.com/open-webui/open-webui/issues/21347), [Commit](https://github.com/open-webui/open-webui/commit/7bda6bf767d5d5c4dc1111465096a88e10b5030e)
+- 🗃️ **SQLite cascade delete fix.** Deleting chats now properly removes all associated messages in SQLite, matching PostgreSQL behavior and preventing orphaned data. [#21362](https://github.com/open-webui/open-webui/pull/21362)
+- ☁️ **Ollama Cloud model naming fix.** Fixed an issue where using Ollama Cloud models would fail with "Model not found" errors because ":latest" was incorrectly appended to model names. [#21386](https://github.com/open-webui/open-webui/issues/21386)
+- 🛠️ **Knowledge selector tooltip z-index.** Fixed an issue where tooltips in the "Select Knowledge" dropdown were hidden behind the menu, making it difficult to read knowledge item names and descriptions. [#21375](https://github.com/open-webui/open-webui/pull/21375)
+- 🎯 **Model selector scroll position.** The model selector dropdown now correctly scrolls to and centers the currently selected model when opened, and resets scroll position when reopened. [Commit](https://github.com/open-webui/open-webui/commit/0b05b2fc7ed4c38af158707438ff404d1beb7c91)
+- 🐛 **Sync modal unexpected appearance.** Fixed an issue where the Sync Modal would appear unexpectedly after enabling the "Community Sharing" feature if the user had previously visited the app with the sync parameter. [#21376](https://github.com/open-webui/open-webui/pull/21376)
+- 🎨 **Knowledge collection layout fix.** Fixed a layout issue in the Knowledge integration menu where long collection names caused indentation artifacts and now properly truncate with ellipsis. [#21374](https://github.com/open-webui/open-webui/pull/21374)
+- 📝 **Metadata processing crash fix.** Fixed a latent bug where processing document metadata containing certain keys (content, pages, tables, paragraphs, sections, figures) would cause a RuntimeError due to dictionary mutation during iteration. [#21105](https://github.com/open-webui/open-webui/pull/21105)
+- 🔑 **Password validation regex fix.** Fixed the password validation regex by adding the raw string prefix, ensuring escape sequences like \d and \w are interpreted correctly. [#21400](https://github.com/open-webui/open-webui/pull/21400), [#21399](https://github.com/open-webui/open-webui/issues/21399)
+
+### 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.
+
+## [0.8.0] - 2026-02-12
+
+### Added
+
+- 📊 **Analytics dashboard.** Administrators now have access to an Analytics dashboard showing model usage statistics, token consumption by model and user, user activity rankings, and time-series charts with hourly or daily granularity; clicking any model opens a detail view with feedback history, associated tags, and chat browser, and results can be filtered by user group. [#21106](https://github.com/open-webui/open-webui/pull/21106), [Commit](https://github.com/open-webui/open-webui/commit/68a1e87b66a7ec8831d5ed52940c4ef110e3e264), [Commit](https://github.com/open-webui/open-webui/commit/e62649f94044abfed4d7d60647a2050383a67e3d)
+- 🎯 **Experimental support for Skills.** Open WebUI now supports the Skill standard — allowing users to create and manage reusable AI skills with detailed instructions, reference them in chats using the "$" command, or attach them to specific models for automatic context in conversations. [#21312](https://github.com/open-webui/open-webui/pull/21312)
+- 🧪 **Experimental support for Open Responses protocol.** Connections can now be configured to use the experimental Open Responses protocol instead of Chat Completions, enabling native support for extended thinking, streaming reasoning tokens, and richer tool call handling for compatible providers. [Commit](https://github.com/open-webui/open-webui/commit/d2c695eb11ddca9fc93499bb0c3fcafcff7099b5), [Commit](https://github.com/open-webui/open-webui/commit/90a057f4005c000bda6ff8703e13e529190af73a), [Commit](https://github.com/open-webui/open-webui/commit/0dc74a8a2e7adb76fb503ef0cd3c02daddd2f4bb), [Commit](https://github.com/open-webui/open-webui/commit/ea9c58ea80646cef05e06d0beaf5e81cc2f78cb1), [Commit](https://github.com/open-webui/open-webui/commit/6ffce4bccdc13b8b61a8b286e34094c981932eda), [Commit](https://github.com/open-webui/open-webui/commit/6719558150920f570d8febe021da65903e53c976), [Commit](https://github.com/open-webui/open-webui/commit/117c091b95a1b1a76a31c31b97304bac289d6f18), [Commit](https://github.com/open-webui/open-webui/commit/aa8c2959ca8476f269786e1317fb6d2938abd3f9), [Commit](https://github.com/open-webui/open-webui/commit/e2d09ac36174de48a7d85bafc8d3291c9ffe44cd)
+- 👥 **Redesigned access control UI.** The access control UI was redesigned with a more intuitive interface that makes it easier to add multiple groups at once. [#21277](https://github.com/open-webui/open-webui/pull/21277)
+- 👤 **Per-user resource sharing.** Resources including knowledge bases, prompts, models, tools, channels, and base models can now be shared directly to individual users alongside the existing per-group sharing capability. [#21277](https://github.com/open-webui/open-webui/pull/21277)
+- 📨 **Message queuing.** Messages can now be queued while a response is generating rather than being blocked, allowing you to continue your train of thought; queued messages are automatically combined and sent when generation completes, and can be edited, deleted, or sent immediately from the input area.

+### Changed
+
+- ⚠️ This release includes a major overhaul of database connection handling in the backend that requires all instances in multi-worker, multi-server, or load-balanced deployments to be updated simultaneously; running mixed versions will cause failures due to incompatible database connection management between old and new instances.
+- 📝 Administrators who previously used the standalone "Markdown (Header)" text splitter must now switch to "character" or "token" mode with the new "ENABLE_MARKDOWN_HEADER_TEXT_SPLITTER" toggle enabled, as document chunking now applies markdown header splitting as a preprocessing step before character or token splitting.

+- 🔐 Scripts or integrations that directly called Image Generation, Web Search, or Audio APIs while those features were disabled in the Admin UI will now receive 403 Forbidden errors, as backend permission enforcement has been added to match frontend restrictions. [#20471](https://github.com/open-webui/open-webui/pull/20471)

+
+### Changed
+
+- ⚠️ This release includes database schema changes; multi-worker, multi-server, or load-balanced deployments must update all instances simultaneously rather than performing rolling updates, as running mixed versions will cause application failures due to schema incompatibility between old and new instances.
+- 📡 WEB_SEARCH_CONCURRENT_REQUESTS default changed from 10 to 0 (unlimited) — This setting now applies to all search engines instead of only DuckDuckGo; previously users were implicitly limited to 10 concurrent queries, but now have unlimited parallel requests by default; set to 1 for sequential execution if using rate-limited APIs like Brave free tier. [#20070](https://github.com/open-webui/open-webui/pull/20070)
+- 💾 SQLCipher absolute path handling was fixed to properly support absolute database paths (e.g., "/app/data.db") instead of incorrectly stripping leading slashes and converting them to relative paths; this restores functionality for Docker volume mounts and explicit absolute path configurations while maintaining backward compatibility with relative paths. [#20074](https://github.com/open-webui/open-webui/pull/20074)
+- 🔌 Knowledge base file listing API was redesigned with paginated responses and new filtering parameters; the GET /knowledge/{id}/files endpoint now returns paginated results with user attribution instead of embedding all files in the knowledge object, which may require updates to custom integrations or scripts accessing knowledge base data programmatically. [Commit](https://github.com/open-webui/open-webui/commit/94a8439105f30203ea9d729787c9c5978f5c22a2)
+- 🗑️ Legacy knowledge base support for deprecated document collections and tag-based collections was removed; users with pre-knowledge base documents must migrate to the current knowledge base system as legacy items will no longer appear in selectors or command menus. [Commit](https://github.com/open-webui/open-webui/commit/a934dc997ed67a036dd7975e380f8036c447d3ed)
+- 🔨 Source-level log environment variables (AUDIO_LOG_LEVEL, CONFIG_LOG_LEVEL, MODELS_LOG_LEVEL, etc.) were removed as they provided limited configuration options and added significant complexity across 100+ files; the GLOBAL_LOG_LEVEL environment variable, which already took precedence over source-level settings, now serves as the exclusive logging configuration method. [#20045](https://github.com/open-webui/open-webui/pull/20045)
+- 🐍 LangChain was upgraded to version 1.2.0, representing a major dependency update and significant progress toward Python 3.13 compatibility while improving RAG pipeline functionality for document loading and retrieval operations. [#19991](https://github.com/open-webui/open-webui/pull/19991)
+

[#18689](https://github.com/open-webui/open-webui/issues/18689), [#19523](https://github.com/open-webui/open-webui/pull/19523), [Commit](https://github.com/open-webui/open-webui/commit/e301d1962e45900ababd3eabb7e9a2ad275a5761)
+- 📦 Knowledge API batch file addition endpoint was corrected to properly handle async operations, resolving 500 Internal Server Error responses when adding multiple files simultaneously. [#19538](https://github.com/open-webui/open-webui/issues/19538), [Commit](https://github.com/open-webui/open-webui/commit/28659f60d94feb4f6a99bb1a5b54d7f45e5ea10f)
+- 🤖 Embedding model auto-update functionality was fixed to properly respect the "RAG_EMBEDDING_MODEL_AUTO_UPDATE" setting by correctly passing the flag to the model path resolver, ensuring models update as expected when the auto-update option is enabled. [#19687](https://github.com/open-webui/open-webui/pull/19687)
+- 📉 API response payload sizes were dramatically reduced by removing base64-encoded profile images from most endpoints, eliminating multi-megabyte responses caused by high-resolution avatars and enabling better browser caching. [#19519](https://github.com/open-webui/open-webui/issues/19519), [Commit](https://github.com/open-webui/open-webui/commit/384753c4c17f62a68d38af4bbcf55a21ee08e0f2)
+- 📞 Redundant API calls on the admin user overview page were eliminated by consolidating reactive statements, reducing four duplicate requests to a single efficient call and significantly improving page load performance. [#19509](https://github.com/open-webui/open-webui/issues/19509), [Commit](https://github.com/open-webui/open-webui/commit/9f89cc5e9f7e1c6c9e2bc91177e08df7c79f66f9)
+- 🧹 Duplicate API calls on the workspace models page were eliminated by removing redundant model list fetching, reducing two identical requests to a single call and improving page responsiveness. [#19517](https://github.com/open-webui/open-webui/issues/19517), [Commit](https://github.com/open-webui/open-webui/commit/d1bbf6be7a4d1d53fa8ad46ca4f62fc4b2e6a8cb)
+- 🔘 The model valves button was corrected to prevent unintended form submission by adding explicit button type attribute, ensuring it no longer triggers message sending when the input area contains text. [#19534](https://github.com/open-webui/open-webui/pull/19534)
+- 🗑️ Ollama model deletion was fixed by correcting the request payload format and ensuring the model selector properly displays the placeholder option. [Commit](https://github.com/open-webui/open-webui/commit/0f3156651c64bc5af188a65fc2908bdcecf30c74)
+- 🎨 Image generation in temporary chats was fixed by correctly handling local chat sessions that are not persisted to the database. [Commit](https://github.com/open-webui/open-webui/commit/a7c7993bbf3a21cb7ba416525b89233cf2ad877f)
+- 🕵️‍♂️ Audit logging was fixed by correctly awaiting the async user authentication call, resolving failures where coroutine objects were passed instead of user data. [#19658](https://github.com/open-webui/open-webui/pull/19658), [Commit](https://github.com/open-webui/open-webui/commit/dba86bc)
+- 🌙 Dark mode select dropdown styling was corrected to use proper background colors, fixing an issue where dropdown borders and hover states appeared white instead of matching the dark theme. [#19693](https://github.com/open-webui/open-webui/pull/19693), [#19442](https://github.com/open-webui/open-webui/issues/19442)
+- 🔍 Milvus vector database query filtering was fixed by correcting string quote handling in filter expressions and using the proper parameter name for queries, resolving false "duplicate content detected" errors that prevented uploading multiple files to knowledge bases. [#19602](https://github.com/open-webui/open-webui/pull/19602), [#18119](https://github.com/open-webui/open-webui/issues/18119), [#16345](https://github.com/open-webui/open-webui/issues/16345), [#17088](https://github.com/open-webui/open-webui/issues/17088), [#18485](https://github.com/open-webui/open-webui/issues/18485)
+- 🆙 Milvus multitenancy vector database was updated to use query_iterator() for improved robustness and consistency with the standard Milvus implementation, fixing the same false duplicate detection errors and improving handling of large result sets in multi-tenant deployments. [#19695](https://github.com/open-webui/open-webui/pull/19695)
+
+### Changed
+
+- ⚠️ **IMPORTANT for Multi-Instance Deployments** — This release includes database schema changes; multi-worker, multi-server, or load-balanced deployments must update all instances simultaneously rather than performing rolling updates, as running mixed versions will cause application failures due to schema incompatibility between old and new instances.
+- 👮 Channel creation is now restricted to administrators only, with the channel add button hidden for regular users to maintain organizational control over communication channels. [Commit](https://github.com/open-webui/open-webui/commit/421aba7cd7cd708168b1f2565026c74525a67905)
+- ➖ The active user count indicator was removed from the bottom-left user menu in the sidebar to streamline the interface. [Commit](https://github.com/open-webui/open-webui/commit/848f3fd4d86ca66656e0ff0335773945af8d7d8d)
+- 🗂️ The user table was restructured with API keys migrated to a dedicated table supporting future multi-key functionality, OAuth data storage converted to a JSON structure enabling multiple identity providers per user account, and internal column types optimized from TEXT to JSON for the "info" and "settings" fields, with automatic migration preserving all existing data and associations. [#19573](https://github.com/open-webui/open-webui/pull/19573)
+- 🔄 The knowledge base API was restructured to support the new file relationship model.
+
+## [0.6.40] - 2025-11-25
+
+### Fixed
+
+- 🗄️ A critical PostgreSQL user listing performance issue was resolved by removing a redundant count operation that caused severe database slowdowns and potential timeouts when viewing user lists in admin panels.
+
+## [0.6.39] - 2025-11-25
