## New Features
- 🧱 **External apps in channels.** Administrators can now turn on Apps in Admin Settings > General, or with "ENABLE_APPS", and connect external apps in the new Apps tab of Admin Settings by their HTTPS address, reviewing the permissions each app asks for, such as reading its mentions, reading channel messages or posting messages, and choosing who may use it; channel managers then add an app to a channel with Add Members in the channel info, where it is listed with the members and its own profile p
- 🎭 **Avatars in Standard voice calls.** A model's avatar now also appears in voice calls that use the Standard call mode, moves with the spoken reply and can play the model's gestures when the model uses native function calling, where avatars and gestures only worked in Realtime calls; the Voice avatar setting in the model editor is now shown even when Realtime is off.

- 🪪 **Profile cards from profile pictures.** Clicking the picture of the person who wrote a message in a shared chat, of a shared chat's owner in the sidebar or of a direct message partner in the sidebar now opens their profile card. Commit

- 🔀 **Compare and merge a revision.** The skill file editor, the prompt editor and the system prompt in the model editor have a Compare revision button, and the chat input has Compare text in its + menu and a /compare command, each opening a side-by-side view where you paste a proposed revision, for example one written by a model, step through each change, copy changes in either direction and apply the result to your draft, the skill file editor also gets a Copy button for the open file, and compa
- 🔕 **Mute channels.** The menu of a channel or direct message now has a Notifications setting where Mentions only mutes it, so it no longer shows an unread count or notifies you unless someone @mentions you. Commit

## Bug Fixes
- 🔓 **Skill editor and more over plain HTTP.** When Open WebUI is opened over plain HTTP at a network address, the skill editor, adding options to model controls, adding gestures to a voice avatar, Realtime voice calls and the Playground chat now work, where they failed with "crypto.randomUUID is not a function" and the skill editor stayed disabled. Commit, Commit, #32238
- 📑 **Page titles for external knowledge citations.** Citations from external knowledge bases such as Qdrant, Milvus or pgvector whose source is a web address now show the page title in the source list below the answer, matching the numbered markers in the text, where the full address was shown. #32232, #32231
- 🧭 **Redis Sentinel master names with capital letters.** With Redis Sentinel, a master name with capital letters in "REDIS_URL", such as myMaster, the default of the OT-Container-Kit redis-operator, now works, where it was lowercased and every Redis call failed with "No master found". #32234, #31918
- 🔐 **Redis Sentinels with a password.** Redis Sentinels protected with a password now work, as the credentials in "REDIS_URL" and "WEBSOCKET_REDIS_URL" are also used for the Sentinels, where every Redis call failed with "No master found"; Sentinel credentials set in "WEBSOCKET_REDIS_OPTIONS" still take precedence. #32241, #32240
- 🔗 **External knowledge citation links.** Clicking the title or Content link of a citation from an external knowledge base such as Qdrant, Milvus or pgvector now opens the cited web page, or shows the title as plain text when the source is not a web address, where it led to a not found error. #32233, #32231
- 🧰 **Tools picked in new chats.** Tools picked from the Integrations menu, the Web Search toggle and a picked skill in a new chat now stay on after switching to another chat and back or reloading, where the chat fell back to the model's default tools and broke prompt caching. #32235, #32084
