## Executive Summary (TL;DR)
Open WebUI v0.11.1. Source highlight: 🚦 **Human in the loop tool approval.** Where an administrator has turned it on, you can switch a conversation from letting tools run freely to being asked first, so a model that wants to use a tool stops and waits for you to allow or deny it, one call at a time in a saved conversation, by button or 

## Breaking Changes & Deprecations
- - 🧠 **Conversations breaking after a model switch.** Switching to a different model once a reasoning model has answered no longer leaves the conversation unusable, where the earlier model's stored reasoning was replayed to a provider that then rejected every later request.

## New Features
- 🚦 **Human in the loop tool approval.** Where an administrator has turned it on, you can switch a conversation from letting tools run freely to being asked first, so a model that wants to use a tool stops and waits for you to allow or deny it, one call at a time in a saved conversation, by button or by keyboard shortcut, with your choice remembered for this conversation and for future ones, switching back to running freely releasing anything already waiting, and automations, channel replies, and 
- 🙋‍♂️ **Models that can ask you a question.** A new built-in tool lets a model pause and put up to three multiple-choice questions to you before continuing, with room to type your own answer instead, and the question survives a reload in a saved conversation, so you can come back and answer it later rather than losing the conversation.

- 🖇 **Agents can now display terminal files directly.** A model can now show a file it made in a terminal directly in its reply, with a preview and a download button, instead of describing a path that led nowhere when clicked, and a new interface setting chooses whether these open in the reply or in the files pane.

- 📶 **Streaming rebuilt from the ground up.** A reply now streams as small pieces of new text instead of resending the whole message so far with every update, so the data sent over a reply grows with its length rather than with its length squared, which on a server with many people chatting at once means far less processor time spent encoding, passing, and decoding those updates, far less load and memory on the shared cache that carries them between instances, and far less work in your browser, wh
- 🪵 **Much faster throughout.** Hundreds of places across the application no longer assemble detailed log text that is switched off and thrown away unread, so sending messages, uploading and indexing files, running searches, signing in, and loading admin pages all get that time back, with the largest gains on busy servers, in long conversations, and on chats that draw from a large knowledge base. #27834, #27837
- 🚀 **Faster model list lookups.** Title generation, tag suggestions, autocomplete, and other background steps of a chat turn now fetch the model list in one go, which keeps other people's responses flowing on busy Redis-backed instances with many models. #27821

## Bug Fixes
- 🎛️ **Settings for the task model.** Administrators can now set the generation parameters used for background work such as titles, tags, follow-ups, search queries, and conversation summaries, either from the admin panel or through "TASK_MODEL_PARAMS", instead of those requests always using a fixed token limit that could cut a summary short. #27604, Commit, Commit
- 🔠 **Interface scaling throughout.** The UI Scale setting and your browser's own text size now resize the whole interface consistently, including the sidebar, menus, dialogs, and file browser, rather than leaving parts of it fixed. Commit, Commit, Commit, Commit
- 📏 **Widening the chat controls pane.** The controls pane can now be dragged as wide as you like, where it stopped at a fixed limit regardless of screen size. Commit
- 💓 **Tunable heartbeat for live updates.** A new "WEBSOCKET_HEARTBEAT_INTERVAL" setting controls how often each open tab checks in with the server, where it was fixed at 30 seconds, so a large deployment can cut background traffic that no one asked for. Commit, #28166
- 🛡️ **Security Advisory**: This release includes security and access-control fixes. We recommend updating production deployments at your earliest convenience. Not all security fixes in this version may be enumerated in the fixed section. Some may be withheld for a short time to give administrators time to upgrade. Advisories
- 🛂 **Knowledge search reaching past what you may read.** Searching knowledge bases now applies the list of collections you are allowed to open, where that restriction was handed to the vector store and silently discarded, so results could include material from knowledge bases you have no access to.
