 - 🎛️ **Filtering the admin model list by where a model comes from.** The models page in the admin settings can now be narrowed to the base models a connection offers or to the ones built in the workspace, alongside the filters for enabled, disabled, visible and hidden. [Commit](https://github.com/open-webui/open-webui/commit/9e634c0c56e0a060717f1e24a11b082daf664036)
 - ⚡ **Searching without holding up the server.** Searching the text of chats and knowledge now runs beside the rest of the server rather than in front of it, so a long search no longer keeps other requests waiting. [#29621](https://github.com/open-webui/open-webui/pull/29621)
 - 🔢 **Knowledge listings come back in an order you asked for.** The `ls`, `tree` and `find` commands a model runs over a knowledge base now sort by name, and take `-t`, `-S` and `-r` for newest first, largest first and reversed, combinable as in a shell; `ls -t` was accepted and quietly dropped before, so the model was handed whatever order the database gave and read it as newest first. [#29840](https://github.com/open-webui/open-webui/pull/29840)
+- 🪪 **Backends can tell an API key from a browser session.** Where user info headers are forwarded, a request to an OpenAI or Ollama connection now carries `X-OpenWebUI-Auth-Type`, saying whether the person behind it signed in through the browser or called with an API key, and `{{AUTH_TYPE}}` can be put in a connection's custom headers; the header's name is set with `FORWARD_USER_INFO_HEADER_AUTH_TYPE`.

 - 🔄 **General improvements.** Various improvements were implemented across the application to enhance performance, stability, and security.

 - 🌐 **Translation updates.** Translations for Japanese, Traditional Chinese, Korean, Finnish, Russian, Ukrainian, German, Spanish, and Portuguese (Brazil) were enhanced and expanded, and text that had been fixed in English, from the headings grouping the settings pages to labels and messages across the admin pages, the workspace and notifications, now takes its wording from the interface language.

 - 🔠 **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. [#29493](https://github.com/open-webui/open-webui/pull/29493), [#29488](https://github.com/open-webui/open-webui/issues/29488)
 - 🪞 **Account menu rows light up as one.** An entry in the account menu that carries a pin button beside it, among them Workspace, Notes, Calendar and Automations, highlighted only under the link and left the rest of the row plain, in a shade that did not match the other menus either; the whole row now lights up in the shared colour, in high contrast as well, and a long label no longer pushes the pin out of the menu.

 - 🔲 **Shift-clicking files adds to what is already picked.** Holding Shift over a file in the terminal's file browser threw away the rest of the selection and kept only the new stretch, and clicking a file already picked could not take it back out; a range now joins what is selected, and clicking through a selected file removes its range.

+- 🛟 **Attaching a file no longer writes over one already there.** Attaching a file to a message on an instance that puts attachments in a terminal's working directory replaced whatever file of that name was sitting there; the upload now takes the next free name, `report (1).pdf` beside `report.pdf`, and the attachment shows the name it was saved under. Two uploads arriving at the same moment from different browsers can still land on the same name. [Commit](https://github.com/open-webui/open-webui/commit/d70053e44993f271d534fb87d2b40724b028fca2)
 - 📛 **An upload that fails says so.** A file that could not be written to the terminal passed in silence and the browser refreshed as though it had arrived, in a directory that may no longer have been the one on screen; a failure now names itself, and the listing is only reread where it is still the one you are looking at.

 - 🎯 **A question carried in a link is sent once it is written.** Opening a chat from a link holding a question sent it before the box had it, so a question naming a variable went off with the variable unfilled; the send now waits for the text to be in place and filled in.

 - 📜 **A long list of tasks keeps to its own corner.** The list of steps a model works through ran as long as it needed and pushed the rest of the reply down the page; it now stops at a quarter of the window's height and scrolls within itself.
