Every action button on a response message gates its visibility on
'isLastMessage || ($settings?.highContrastMode ?? false)' so that buttons
stay visible (not hover-only) when High Contrast mode is on. The two
Regenerate buttons — the one inside RegenerateMenu and the fallback in the
{:else} branch — were missed and still gated on isLastMessage alone, so on
any non-last message the Regenerate icon was invisible until mouse-over even
with High Contrast enabled (#27638).
Add the same highContrastMode clause to both buttons, matching the other
action buttons in this file.
The "expand input" button was positioned with `fixed top-0 right-0`. That only kept it near the composer by accident: `#message-input-container` sets `backdrop-blur-sm`, and a backdrop-filter makes an element the containing block for fixed descendants, so the button resolved to the top-right corner of the entire composer instead of the text area it belongs to.
That corner is already taken. The `@`-tagged model chip renders as the first row of the same container with its dismiss button at the right end, so with a multi-line prompt and a tagged model the two controls are drawn on top of each other. The attached-files row has the same problem: the button paints over the first thumbnail and its remove button.
Anchor the button to the wrapper that holds the text area instead, using `relative`/`absolute`, so it always sits at the top-right of the input row and below whatever rows precede it. With no chip and no files the position is unchanged. As a side effect the button is no longer a child of the `overflow-auto` scroller, so it can no longer be clipped or scrolled out of view on long prompts.
Fixes#26736
The chat delete endpoints gate on chat.delete for non-admins, but none of
the UI affordances that reach them were conditioned on it, so a user
without the permission is offered controls that always fail with
"Access prohibited".
Gates every entry point on the same condition the backend enforces,
matching the existing chat.share / chat.export / chat.import gates in the
same components:
- Sidebar chat menu (ChatMenu) Delete item — also covers the Search
modal's menu, which reuses ChatMenu
- Sidebar Shift+hover inline Delete button (ChatItem)
- Sidebar hidden #delete-chat-button keyboard-shortcut target (ChatItem)
- Chat navbar menu Delete item (Navbar/Menu)
- Search modal Shift-held inline Delete button (SearchModal)
- Settings -> Data Controls -> Delete All Chats
- Settings -> Archived Chats per-row Delete
A message referencing a file that no longer exists rendered a broken
image, because nothing anywhere noticed the failed load. What the user saw
depended on the caller's alt text: in a response the alt is the message
content, so the entire reply was rendered inside the image frame, and the
preview still opened full-screen on a dead image.
Image.svelte now tracks a failed load and renders an 'Image unavailable'
placeholder instead, suppressing the preview for a source that cannot be
shown. The failed state resets when the source changes, so a replaced or
corrected URL is retried. An onError callback lets a caller react without
changing behaviour for the eight existing call sites, which are untouched.
Responses now pass the file name (or 'Generated Image') as alt rather than
the message content, which was never a description of the image.
A message sent while an attachment is still uploading is held in the chat
queue until the file settles. For files that release works, because the
message input calls onUpdate once the upload completes, which refreshes the
queued entry and asks the queue to run.
Attaching a URL takes a different path. uploadWeb sets the item to uploaded
but calls neither onUpdate nor processNextInQueue, and the queue is
otherwise only revisited when a generation finishes or when the chat is
mounted while idle. In a new chat with nothing generating, none of those
happen, so a message queued behind a URL waits with no event able to
release it until the chat is reloaded.
uploadWeb now asks the queue to run when it is done, the same way the file
path already does.
Newer OpenAI chat models put metadata on the opening line of a colon fence block, like :::writing{variant="email" id="48173" subject="Short question" recipient="mail@example.com"}. The tokenizer matched that line and discarded it, so every block rendered under the same generic "Writing" heading no matter what it contained.
The opening line is now parsed into an attributes map on the token and the header uses it: the subject becomes the title, the recipient follows it and the full string is reachable on hover when the row is too narrow for it. Blocks without metadata render exactly as before, and the other fence types get the parsed attributes for free.
Attributes are read only from inside the {...} braces, not from the whole opening line. Scanning the whole line turned ordinary prose containing key="value" into metadata, and it backtracked quadratically: a 40k character opening line took 586ms to parse, and that runs again on every re-lex while the message streams. Anchored to the braces it is 0.0ms.
Nothing here turns the recipient into a link or a send action. That metadata is model output and can be steered by whatever is in the context, so a prefilled mail action is a separate decision rather than a side effect of parsing.

KatexRenderer rendered the raw math source through {@html} whenever renderToString threw. throwOnError only suppresses KaTeX ParseError, so a RangeError (maximum call stack size exceeded, reachable with deeply-nested brace input) escaped into the catch and re-exposed the unescaped source. Because the math tokenizer captures everything between the delimiters verbatim, that source can carry an HTML/JS payload which then executed in the viewer's browser on the application origin, a stored, cross-user XSS reachable through normal chat/channel/shared-chat rendering. Escape the fallback so the source is shown as text and is never injected as HTML. Valid math is unaffected, it still renders through the success path.

Adds a multiselect input type for Valves and UserValves so plugin authors can let users pick multiple values from static or runtime-resolved options instead of maintaining comma-separated text fields with hardcoded allowed-value lists in the description.
ENABLED_ITEMS: list[str] = Field(
default=["foo"],
json_schema_extra={"input": {"type": "multiselect", "options": "get_item_options"}},
)
@classmethod
def get_item_options(cls):
return [{"value": "foo", "label": "Foo"}, {"value": "bar", "label": "Bar"}]
Options accept the same shapes as the existing select input: either a static list (strings or {value, label} dicts) or a classmethod name resolved at request time (including __user__ context for UserValves). No backend changes are needed because resolve_valves_schema_options already resolves options independently of the input type.
The new MultiSelect component follows the existing Select portal dropdown pattern and renders checkbox rows that stay open while toggling, with the selected labels shown in the trigger. Values bind as a real string array end to end: the array-to-comma-string conversions in the chat controls valves panel and the valves modal are skipped for multiselect fields, so the stored valve is a native list[str] validated by Pydantic.
Requested in #26848.
* chore: drop redundant background repaints so surfaces inherit their parent
Four spots repaint the exact color their parent surface already provides
(bg-white / dark:bg-gray-900 rows inside same-colored pages and modals,
and the selectClass dark repaint inside the connection modals — the
sibling input const is already fully transparent). Visually identical in
stock light and dark; removing them lets instance theming show through
instead of leaving opaque boxes:
- .tiptap tr (app.css) — table rows in notes/editors
- Edit User Group Users tab body rows (common Modal surface)
- AddToolServerModal + AddTerminalServerModal selectClass dark repaint
The matching repaints inside the ModelUsage/UserUsage components are
not part of this change — those files were dead code and were removed
entirely in #27574.
* chore: catch remaining redundant surface repaints missed in the first pass
Same rule as the previous commit — every one of these repaints the exact
color its parent surface already provides, so removal is stock-identical
in light and dark while letting instance theming show through:
- Analytics Dashboard's inline Model Usage / User Activity row markup
(the Analytics tab renders these tables from Dashboard.svelte itself;
the unreferenced ModelUsage/UserUsage component files were removed
in #27574)
- Evaluations Feedbacks + Leaderboard body rows (settings modal surface)
- admin UserList body rows (app page surface)
- chat markdown tables (MarkdownTokens): thead and body rows — unlike
the tiptap header (gray-850 contrast, untouched), this thead painted
the page's own color
- CitationsModal source rows (common Modal surface)
- AddConnectionModal selectClass dark repaint — third copy of the same
const already fixed in AddToolServerModal / AddTerminalServerModal
* feat: add default upload mode setting
Add user setting to configure the default upload mode for files, allowing users to choose between "Using Entire Document" (full context) and "Using Focused Retrieval" (RAG processing) as the default behavior.
* i18n: sync locale catalogs for the new upload mode strings
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* chore: re-trigger CI (previous run hit the pre-existing Node heap OOM, see #27254)
* fix: apply the default upload mode at upload time so the payload carries it
The previous approach only pre-set the modal toggle's visual state on
mount; item.context is written solely by the Switch's on:change, so the
sent files kept context: undefined and the backend never saw 'full'. It
also showed a misleading ON state for legacy context-less files, since
FileItemModal mounts with every FileItem chip render.
Stamp context on the fileItem in uploadFileHandler instead (before
...itemData, so callers passing an explicit context still win) and
revert the FileItemModal hunk — the modal already renders from
item.context alone.
