Deleting an external knowledge base now clears its connection only when an admin removes the last knowledge base referencing it, matching the connection delete route.
The binary branch of the web fetch read the entire response body into memory
before writing it out. It now streams in blocks, applies the configured file
size limit the same way the sibling URL endpoint already does, and removes the
temporary file when a download fails partway instead of leaving it behind.
stop_item_tasks() ran unconditionally while create_task() only ran when the
update carried data, so an update without a content snapshot cancelled the
pending save without scheduling a replacement and the edits were never
written.
With delta streaming most websocket frames are tiny per-token deltas, and
per-message-deflate pays zlib work on every outgoing frame per subscriber for
near-zero gain there; under heavy streaming that shows up as measurable server
CPU. The frames that still benefit are the rare large ones (final message,
sources), and even a 100k token message is only a few hundred KB uncompressed,
which any network delivers without noticeable delay.
UVICORN_WS_PER_MESSAGE_DEFLATE=false (default true, current behavior) disables
the extension in every entry point: open-webui serve and dev, start.sh both
invocations, start_windows.bat and dev.sh. Verified against a running
instance: with the flag off the server declines the client-offered
permessage-deflate extension, with defaults it still negotiates it.
Presence tracking writes each user's last_active_at on every authenticated request, every API key request and every websocket heartbeat. The throttle for it already exists but ships unset, and unset means no throttle at all, so a stock deployment pays one UPDATE plus COMMIT per user per request. The 30 second frontend heartbeat alone is 2 write transactions per minute per open tab, before any actual UI traffic.
Defaulting the throttle to 60 seconds collapses that to at most one write per user per worker per minute. Presence is only ever read at minute granularity, so nothing visible changes.
60 rather than the 300 to 500 the docs currently suggest, because a user counts as active for 3 minutes after their last write and that window is hardcoded in the backend and again in the frontend. Any interval at or above 180 seconds makes people who are actively using the instance drop out of the active user count. Letting the window follow the interval instead would need the value shipped to the client, so that is a separate change.
0 still disables the throttle, and now costs nothing at all: the decorator returns the undecorated function instead of a wrapper that re-checks a constant on every call.
Closes#28165
nltk.download picks the first entry of nltk.data.path that already exists and is
writable. None do here, so punkt_tab lands in /root/nltk_data, and /root is mode
0700. The corpus is then unreachable whenever the container does not run as
root:
nltk.data.find('tokenizers/punkt_tab')
LookupError: Resource punkt_tab not found.
/usr/local/share/nltk_data is already on nltk.data.path, so nothing changes at
the read side.

Moving a folder under one of its own subfolders was accepted. A folder in a parent loop is never a root, so it and everything under it silently disappeared from the sidebar, and there was no way to get it back from the UI.
The move is now rejected with a 400, folders whose parent chain loops are put back at the root on the next folder list, and the folder tree traversals skip ids they have already visited so existing data in that state stays workable.
* fix: stop unsaved group settings from persisting into the group list state
* fix: key the groups list so an open modal cannot rebind to another group
