The three community origins were repeated inline in five window message handlers and now come from a single COMMUNITY_ORIGINS constant in constants.ts.
The sync stats modal uses that same list in both directions: it reads messages only from a community origin, replies to the origin the message came from, and names the community origins as the targets of the messages it sends. Its chat id goes into the request as one encoded path segment.
Link URLs rendered from markdown, citations and web search results now pass a scheme check before they reach an anchor. A new safeLinkUrl helper sits beside isValidHttpUrl and keeps http, https, mailto, tel and relative URLs, returning undefined for anything else so the label renders without a link. Markdown links with an unusual scheme (ftp, sms, and application deep links such as obsidian or vscode) render as plain text from now on.
The citation checks move off a substring test for "http" onto isValidHttpUrl, which is what Citations.svelte already uses for the same question. That also drops two long-standing quirks: an uppercase HTTP:// source never rendered as a link, and a filename merely containing "http" rendered as a dead external one.
Setting ENABLE_PROFILE_IMAGE_URL_FORWARDING=false stops the user and model profile image endpoints from redirecting browsers to external avatar URLs, but channel webhook avatars kept redirecting regardless. An operator who turned the setting off precisely to stop clients leaking their IP, User-Agent and Referer to outside origins still leaked all three whenever anyone viewed a channel message posted by a webhook with an external profile image URL.
The webhook profile image endpoint now reads the same setting the user and model endpoints already read, and serves the bundled default image instead of the redirect when forwarding is off. Stored URLs are untouched, so turning the setting back on restores the previous behaviour.
Verified against the real handler with seeded webhook rows: with the setting unset or true the endpoint still returns the 302 with the original Location, with it false it returns the default favicon as image/png with no Location and no header carrying the external host, and the data URI, no image and unknown webhook responses are byte identical in both states.
* fix: drop thinking blocks when converting Anthropic Messages requests to Chat Completions
Claude Code and other Anthropic SDK clients pointed at /api/v1/messages send the assistant's earlier thinking blocks back with every follow-up request. Since 0.11.0 those blocks were copied into the OpenAI assistant message as content parts of type thinking, a part type Chat Completions does not define. Strict OpenAI-compatible servers such as NVIDIA Dynamo reject the whole request with 400 "data did not match any variant of untagged enum ChatCompletionRequestAssistantMessageContent", so a conversation with a reasoning model died on its second turn. The error reports its position at the very end of the body, which made the request look cut off; it was complete.
Thinking and redacted_thinking blocks are now skipped in the conversion, which is what happened before 0.11.0. An assistant turn that held only thinking blocks is kept as an empty assistant message so the turn order survives. Native Anthropic and LiteLLM connections are unaffected because they receive the request untouched, and thinking blocks in responses are still produced.
Fixes#29799
* fix: keep signed thinking blocks when converting Anthropic Messages requests
Dropping every thinking block also removed the signed ones. Those are the blocks a gateway such as LiteLLM forwards to Anthropic, which needs the signed thinking block of the previous assistant turn when a tool-use turn continues with extended thinking. Only the unsigned blocks are the problem: Open WebUI creates them itself from reasoning_content, and strict Chat Completions backends reject them because thinking is not a content part type they know.
Unsigned thinking blocks are now dropped while signed thinking and redacted_thinking blocks are kept, the same rule LiteLLM applies before forwarding to Anthropic and the rule the native chat path already uses for Anthropic reasoning details. Backends that never emit a signature, such as NVIDIA Dynamo and vLLM, keep receiving requests without thinking parts, so the original failure stays fixed.
Pressing Stop on a chat that has more than one running task (a multi-model
response, or a follow-up sent from another tab or device while a response
is still streaming) reported success but only cancelled the first task.
The survivors kept streaming and kept executing tool calls until the
iteration limit, which is the runaway reported in the issue.
Without Redis the stop loop iterates the live task-id list of the chat.
Each awaited cancellation runs that task's cleanup, which removes its id
from the same list mid-iteration, so the loop runs out one element early
and the last task is never cancelled. Returning a snapshot of the list to
callers keeps the loop on the ids it started with. Redis deployments
already got a fresh list from the set and were not affected.
Verified against a mock upstream that calls a tool on every turn: with three
tasks on one chat, stop left one or two alive before the change and cancels
all of them after it.
Fixes#29816

Streamed chat completions and the other proxied OpenAI and Ollama responses
went out with two Server and two Date headers: the upstream's copies, forwarded
verbatim, plus uvicorn's own. nginx in front of Open WebUI logs "upstream sent
duplicate header line" for both on every streamed request.
Server and Date belong to whoever terminates the connection, so both proxies now
drop the upstream's copies next to the encoding headers they already stripped.
The filter also compares header names case-insensitively. Before, it matched
title-case names only, so uvicorn-based upstreams such as vLLM and LiteLLM,
which send lowercase header names, had none of their headers stripped at all,
including the Content-Encoding entry the filter exists for.
Same fix as #29824 for the terminal proxy, applied to the other two proxy paths.
Opening the workspace model editor with an id that cannot be loaded redirected back to the model list and then fell through into the write-access check on the same empty model, so a plain not-found id produced "You do not have permission to edit this model". The message pointed people at their permissions for something that was never a permission problem.
The editor now stops after the redirect, so that message only appears when the model loaded and the user really cannot edit it.
Refs #29629
Proxied terminal responses (GET /api/v1/terminals/{id}/ports and every other
proxied route) went out with two Server and two Date headers: the terminal
server's copies, forwarded verbatim, plus uvicorn's own. nginx in front of Open
WebUI logs "upstream sent duplicate header line" for both on every request, and
the ports route is polled often enough to fill gigabytes of error log per day.
Server and Date belong to whoever terminates the connection, so the proxy now
drops the upstream's copies next to the framing headers it already stripped.
uvicorn's own values still go out, once. Everything else, including custom
upstream headers and TERMINAL_PROXY_HEADERS, passes through unchanged.
The OpenAI and Ollama proxies forward upstream Server and Date the same way and
are left for a separate change.
Fixes#29824
kb_exec silently ignored ls -t. It accepted the flag, dropped it and
returned the same undefined database order as a plain ls, so the model
believed it had a newest-first list when it did not. With a few thousand
files in a knowledge base there was no way to ask what changed recently
without reading the whole listing and comparing dates by eye.
ls, tree and find now sort their file lines by name by default, so the
same knowledge base always lists the same way. -t sorts newest first,
-S largest first and -r reverses, combinable like -at or -tr, matching
the flags the model already knows from a shell. Directories keep their
existing name order and stay grouped first. No query changes: the
timestamps and sizes were already loaded for the date and size columns.
