 - 🧩 **Tool steps stay in a finished reply.** A reply that called tools showed each step as it ran, then lost them the moment the reply completed, because the provider's closing message replaced everything on screen rather than joining it; the closing message is now merged into what is already there, and a tool call is no longer mistaken for its own result. [Commit](https://github.com/open-webui/open-webui/commit/e1bfefdf9f8f2012cecfc7d81079bd6fff147932)
 - 🙋 **Answering in your own words lets you send.** Where the last question a model asks is answered by typing into the other field rather than picking an option, the button that sends the answers stayed greyed out however much was filled in; it now follows what has been entered. [#29494](https://github.com/open-webui/open-webui/pull/29494), [#29311](https://github.com/open-webui/open-webui/issues/29311)
 - 🎚️ **Settings you may change save even where others are barred.** An account without permission to change the interface settings had every settings save refused outright, its notification and tool server settings among them; the settings it may not touch are now left as they are and the rest saves. [Commit](https://github.com/open-webui/open-webui/commit/98a920168e2eea435ac15e1ad3d679946631e41d)
+- 🗜️ **Saving one setting no longer rewrites the rest.** Every save sent the whole settings object back, so whatever the page happened to be holding was written into the account, another tab's older copy included, and a default an administrator changed afterwards never reached anyone who had saved anything; only the settings actually changed are stored now, and clearing the default system prompt clears it rather than leaving the old one behind. [Commit](https://github.com/open-webui/open-webui/commit/98a920168e2eea435ac15e1ad3d679946631e41d)
 - ⚠️ **A settings save that fails says so.** Settings that could not be saved were shown as saved anyway until the page was reloaded, because the interface stored them locally without waiting on the server; a failure now raises an error and leaves the panel as it was. [Commit](https://github.com/open-webui/open-webui/commit/98a920168e2eea435ac15e1ad3d679946631e41d)
 - 🔠 **Menu text follows the interface scale.** The entries in the menus that drop down across the interface, among them the account menu and the menus on a chat, were pinned to a fixed size and stayed put while the menu around them grew; they now scale with the rest of the interface.

 - 🧯 **Reading a web page leaves the log alone.** Fetching a page through the browser-driven loader filled the log with tracebacks where the page closed while it was still pulling pieces of itself, as sites behind Cloudflare and similar do; those requests are now let go of before the page closes.

 - 🧰 **Slim installs no requirement from a git address.** The slim image no longer carries git, so a tool or function whose requirements point at a `git+https://` address fails to install and needs the standard image or a published package. [Commit](https://github.com/open-webui/open-webui/commit/30eed1251301f74e0dfeaad09c41e81320f790fc)
 - 🧾 **Tools importing packages they never declared stop working.** Packages that sat in the image only by accident, among them nltk, pymongo, the Google Drive client and the Gemini SDK, are no longer installed, so a tool or function importing one stops working on upgrade until it names the package in its own requirements; an instance that cannot reach the package index needs the package built into the image instead.

 - 🔗 **Default suggestions answer with an object.** `POST /api/v1/configs/suggestions` now answers with an object holding the suggestions and their per-language wording, in place of the bare list it returned before, so anything calling it directly has to read the new shape.

-- 🧷 **Personal settings save one field at a time.** `POST /api/v1/users/user/settings/update` now takes only the settings that changed rather than the whole interface object: a field left out keeps its value and a field sent as null goes back to whatever the administrator's default says, which anything writing settings directly will need to follow.

+- 🧷 **Personal settings are written a field at a time.** `POST /api/v1/users/user/settings/update` now patches the settings named in it rather than replacing the whole interface object: a field left out keeps its value, a field sent as null goes back to the administrator's default, and anything writing settings directly has to follow suit.

 - 🪵 **A refused model says why in the log.** A request turned away with "Model not found" now writes a warning naming the account, the model and the reason it was refused, whether the model is not registered, the account holds no grant on it, or a base model behind it is out of reach, while the message the caller sees stays as vague as before.
