feat(ai-components): generated UI, with A2UI and OpenUI renderers - #3393
Bring generated UI to v15. An agent can answer with UI: the agents router puts a reply's A2UI or OpenUI block in the message's ai_ui field, and what the person does goes back as ai_ui_action. This shipped on v14 in 14.16.0 (#3388); master didn't have it yet.
π Implementation details
Ports what #3388 added, on top of v15's ai-components:
src/plugins/AIComponents/GenerativeUI/: the format-agnostic AIUIHost, renderer, document, action, component definitions, view, entrance, runtime loader and error boundary, exported from stream-chat-react/ai-components.
New entries stream-chat-react/a2ui (ESM only; require throws saying so) and stream-chat-react/openui, which load @a2ui/web_core + @a2ui/react 0.15 and @openuidev/react-lang + react-ui the first time a reply shows them. These are optional ~ peers; zod moves to ^4.2.0.
vite.config.ts entries plus withoutUnreachableEntries, so each format ships only entries something can load; package.json exports and typesVersions.
ai-ui, a2ui, openui and _ai-ui-icons styles in ai-components.css; README sections for Generated UI, A2UI and OpenUI.
The renderers, generated-UI code and styles match v14 apart from the changes below. The merged AIConversation.tsx and entries.ts equal v14 plus master's own v15 changes.
Adapted to v15:
Custom fields.fromStreamMessage reads ai_ui through withCustomFields, so it finds custom.ai_ui on a stream-chat v10 message and ai_ui at the top level of a message straight from the API, as it does ai_generated. The renderer and conversation tests build replies the v10 way.
Translation keys. The A2UI ChoicePicker filter and Modal close button use the core common.search.ariaLabel and common.close.ariaLabel in place of v14's English keys. The filter's placeholder gets its own key, aiComponents.a2ui.choicePickerFilter.placeholder, which is added to the README table and ai-docs/i18n-v15-key-map.json.
Bundle checks.validate-entry-isolation now also keeps the main and ai-components entries off the A2UI and OpenUI plugins and their packages; the ESM smoke test imports a2ui.mjs and openui.mjs; the CJS one requires openui.js and checks that require of a2ui says it is ESM only.
utils.isObject reuses the generated UI's React-free isRecord rather than duplicating it.
yarn dedupe keeps one @floating-ui/react-dom; the new packages otherwise split it, which broke yarn types.
Button, Form, icons, tokens and theming needed no changes: the components and icon names the A2UI renderer uses exist unchanged on v15, and class names stay the same.
Checked locally: yarn lint, yarn types, yarn types:scripts, yarn test (319 files, 3,676 tests with all three commits), yarn build (leaves keys.ts as committed), validate-cjs, validate-esm, validate-entry-isolation. examples:build (run as CI does, with NEXT_TELEMETRY_DISABLED=1) builds all four examples; the vite example's German and Italian dictionaries translate the new aiComponents.a2ui.choicePickerFilter.placeholder key.
The second commit brings over the v14 follow-up, generated UI parity with iOS and Android: secrets stay on the device, the person's message is what they pressed, tools that change something run only from a tap (AIUIClientTool.readOnly, runTool's userInitiated), the app's tools in both formats' instructions and A2UI @call, a mediaUrl check before media loads, OpenUI Query caching, the renderers' instructions option, A2UI basicComponents overrides and OpenUI unknown-action errors. It applied without conflicts; only its tests changed, to render with render instead of v14's renderWithEnglish. Behaviour change (as on v14): a tool without readOnly: true runs only from a tap.
The third commit fixes three issues #3394 has on v14 too, each with a test that fails without it:
OpenUI runs a tool that changes something only within 5 s of a press on a control in that reply. Before, it relied on the browser's page-wide navigator.userActivation, which pressing Enter to send a message also sets. Browsers without userActivation can now run Mutations from taps.
OpenUI keeps a password bound to a $variable out of an action's context and message when its form also has unbound fields. OpenUI then passes only the form's own values, which don't include the variable.
A2UI resolves an obscured field's relative path from where it is drawn, such as a list's row, so a PIN typed there stays out of the data model and the button's context.
None to existing components. Generated UI renders only with an AIUIHost passed to AIConversation, styled as on v14.
Summary by CodeRabbit
New Features
Added support for displaying generated A2UI and OpenUI experiences in conversations, including streaming updates, loading states, and text fallback when a renderer cannot display a reply.
Added reusable and app-defined components, interactive controls, actions, and tool integrations.
Added themed styling, accessibility support, and reduced-motion behavior for generated interfaces.
Added dedicated import paths for A2UI and OpenUI. Media is limited to permitted URLs, and sensitive values are excluded from actions.
Added search translations for A2UI choice pickers in English, German, and Italian.
Documentation
Added setup and integration guidance for generated UI and renderer options.
Ports the generated UI of 14.16.0 (#3388) from release-v14 to v15: the
format-agnostic AIUIHost and its views in stream-chat-react/ai-components,
AIConversation's `ui` prop, and the lazily loaded renderers in the new
stream-chat-react/a2ui (ESM only) and stream-chat-react/openui entries,
whose packages are optional peers.
Adapted to v15:
- fromStreamMessage reads a reply's `ai_ui` under `custom`, where
stream-chat v10 keeps it, as it does `ai_generated`.
- The A2UI renderer uses v15's namespaced translation keys: the core
`common.search.ariaLabel` and `common.close.ariaLabel`, and a new
`aiComponents.a2ui.choicePickerFilter.placeholder`.
- The entry isolation check keeps the main and ai-components entries off
the renderers and their packages; the ESM and CJS smoke tests load the
new entries.
No actionable comments were generated in the recent review.
Walkthrough
This change adds Generated UI support to AIConversation and introduces A2UI and OpenUI renderers. Assistant messages can carry UI documents that a configured host routes to a matching renderer. The change also adds package exports, styles, translations, documentation, and bundle validation.

The accessibility test checks roles and names by hand. No test under src/plugins/A2UI runs an axe check. AGENTS.md asks new interactive UI, such as the A2UI button, text field, choice picker and modal, to ship an axe assertion in its tests. Sibling tests in src/plugins/AIComponents/__tests__ import axe from axe-helper. Use the same import here.
If the jsdom color-contrast rule reports a false violation, disable it for this assertion as a11y.test.tsx does.

Bring the reply up to date before showsNothing checks its surfaces.
A streaming reply can keep a stale surface count. Once the complete document arrives, showsNothing can return true for that stale reply. view then returns null and unmounts A2UIReplyContent, so its layout effect never applies the new messages.
Only replyOf and the A2UIReplyContent layout effect call reply.update. While a document streams, showsNothing does not call replyOf. A2UIReplyContent creates the reply in that phase. If its messages produce no surface, the cached reply keeps zero surfaces. The complete document then reads that cached reply, and view returns null on every later render.
The reply then shows its text instead of its UI.

update skips messages it has already applied. Calling it during view can notify subscribers that are still mounted, which can cause React's "Cannot update a component while rendering" warning. If that happens, defer the notification from this path.
Add a test for a reply that streams a surface-less document and then completes with createSurface and updateComponents.

Hide copy and share when the reply has no text.
For a reply that answers only in UI, message.text is ''. AIConversation passes that value to AIReplyActions through text={message.text}. AIReplyActions writes text to the clipboard and passes it to the share sheet without checking it. The copy button then shows "Copied" while the clipboard holds an empty string.

Reject trailing-dot hostnames in the private-host check.
new URL('http://localhost./x').hostname is localhost.. The anchored PRIVATE_HOST regex does not match this value. isPublicWebURL therefore returns true, and aiUIPublicMediaURL allows the URL. The same bypass works for foo.local. and foo.internal.. The agent writes these URLs, so a prompt-injected reply can make the browser request a service on the person's own device or network. This is the threat the policy exists to block.
Strip one trailing dot before the test. Consider adding 100.64.0.0/10 (CGNAT) and 0.x.x.x to the pattern as well.

- OpenUI runs a tool that changes something only within 5 s of a press on
a control in that reply, rather than whenever the browser's page-wide
activation is active, which sending a message also gives. Browsers
without `navigator.userActivation` can now run Mutations from taps.
- OpenUI leaves a password bound to a `$variable` out of an action's
context and message, from the reply's whole state, when its form's own
values don't hold it.
- A2UI resolves an obscured field's relative path from where it is drawn,
such as a list's row, so what the person types there stays on the
device, in the data model and in a button's context.

- A reply's `content` is an OpenUI Lang program, which shows as the agent writes it, as OpenUI's own renderer shows it. A finished reply with no program, or one that draws nothing, such as words that aren't OpenUI, shows its text.
- The agent writes with OpenUI's chat library (`openuiChatLibrary`), or with the `library` the renderer is given. The app's components join it under their OpenUI name (`place_card` is `PlaceCard`), wherever the library's own content goes, such as a Card's children or a TabItem's content, as on iOS. One whose name the library already has is left out. A parameter takes the value its schema describes, and the component gets it once it fits, dates as dates.
- What the person does goes to `host.send` as an `AIUIAction`, as on iOS and Android: a button or follow-up is `continue_conversation`, with what the control they pressed says as the label, and `{ context, message, params, form, values }` as its payload, where `message` is what the program wrote for the agent and `values` are the values of the form it belongs to. What the person types in a password input is left out of all of it and of what the host keeps. An action the library defines but the agent can't take isn't sent, and `onError` says so. An app component's event has its own label and payload, plus `component`. `@OpenUrl` and the links of its Markdown open through `host.open`.
- A program's `Query()` and `Mutation()` run the host's client tools, or the renderer's `toolProvider`: one that isn't read-only only within 5 s of the person pressing a control in that reply's UI, such as a button (a press elsewhere on the page, such as sending a message, doesn't count), and a Query asking the same again within 5 s gets the answer it got, however often the agent asks it to refresh. Images load only what `mediaUrl` allows, as in A2UI.

Clarify that custom providers do not inherit the host safeguards.
engine.options.toolProvider replaces hostToolProvider, so the runtime does not apply the 5 s mutation gate or Query cache to an app-supplied provider. The README wording can imply that it does. State that these guarantees apply only to the default host client tools, or document equivalent safeguards as the custom provider's responsibility.
This is a minor documentation issue. The provider is app-supplied, so the wording does not establish a direct security failure in the library.

Review comment at @src/plugins/AIComponents/README.md at line 226:
Clarify the README description of Query() and Mutation(): the 5-second mutation
gate and Query cache apply only to the default host client tools, not to
engine.options.toolProvider when it replaces hostToolProvider. State that
app-supplied providers must implement equivalent safeguards if required.

β¦reply (#3395)
### π― Goal
Fix three issues #3394 shipped on v14, which
a review of its v15 port (#3393) found. Each
one lets something get past a guarantee #3394 added: a tool that changes
something running without a tap, or a password reaching the agent.
### π Implementation details
- **A tool that changes something runs only from a tap on the reply.**
OpenUI's `hostToolProvider` read `navigator.userActivation.isActive`.
That flag is page-wide and stays set for a few seconds after any click
or key press, including pressing Enter to send a message, so a Query in
the reply that streams back could run a non-read-only tool.
`hostToolProvider` now takes an `isActing` callback, which
`OpenUIReplyContent` makes true within `TOOL_PRESS_MS` (5 s) of a click
on a control in that reply. Browsers without `userActivation`, which
before could never run a Mutation, now run them from taps.
`isPersonActing` stays exported, and its comment now explains why the
renderers don't use it.
- **An OpenUI password bound to a `$variable` stays out of the action.**
When a form has an unbound field, OpenUI passes only the form's own
values as `formState`, which don't include a `$pw` bound to a password
input. `withoutSecretValues` then had nothing to remove, and
`@ToAssistant("β¦", {pw: $pw})` sent the password. `actOn` now also
collects secrets from the reply's whole OpenUI state, which it keeps
from `onStateUpdate`.
- **An A2UI obscured field in a list row stays on the device.**
`secretPathsOf` turned a relative `@path` into `/<path>`, but in a List
template it resolves against the row, such as `/accounts/0/pin`. So the
PIN went out with `sendDataModel` and in bound context. `placesOf` now
walks the surface from `surface.rootId` as A2UI draws it, with a
template once per item, and resolves each obscured field's path from
where it is drawn. `secretContextKeys` checks a button in every place it
is drawn.
Tests: one new test per issue, and #3394's tool test rewritten for the
new rule. All five fail on `release-v14` without the fixes and pass with
them.
The same fixes are on v15 in #3393 (commit `94cc166a9`). This branch
applies that commit; only one test changed, to render with
`renderWithEnglish`.
Checked locally: `yarn lint`, `yarn types`, `yarn test` (261 files,
3,394 tests), `yarn build`, `validate-cjs`, `validate-esm`,
`validate-entry-isolation`, `validate-translations`.
### π¨ UI Changes
None.
β¦h media URLs exactly in a test
The vite example's German and Italian dictionaries are complete, and
their type check failed on the new
`aiComponents.a2ui.choicePickerFilter.placeholder` key.
The OpenUI media test matched a URL by prefix, which CodeQL flags as
incomplete URL sanitization; it now compares the exact URL.
β¦sUI and approval arguments (#3412)
Ticket: https://linear.app/stream/issue/REACT-1517
### Goal
Bring #3399 (released on v14) to v15, so
`stream-chat-react/ai-components` themes generated UI the same way on
both majors. Setting only the `--str-chat__ai-*` tokens themes A2UI and
OpenUI replies in light and dark, inside or outside a `.str-chat`
element. A custom `AssistantMessage` learns whether the reply's UI
shows, approval cards show what a call will send, and the default A2UI
catalog id no longer names a domain. #3399 named the master port as a
follow-up; this is it.
### Implementation details
A cherry-pick of `fe78a5d7d` (#3399) onto `master`. #3394 and #3395, the
other generated-UI PRs from the same day, are already on `master` as
part of #3393, so this is the only one left.
Applied as is: the A2UI and OpenUI styling (`a2ui.scss`, `openui.scss`,
`_tokens.scss`, `ai-message-parts.scss`, `index.scss`), `showsUI` /
`uiFailed` on `AIConversationAssistantMessageProps` and
`AIUIHost.hasFailed`, `AIToolArguments` and
`AIToolApprover.argumentsPreview`, `A2UI_DEFAULT_CATALOG_ID` as
`stream-app-catalog` with `A2UI_LEGACY_CATALOG_ID` still rendered, the
`validate-ai-ui-tokens` script with its audit and tests, and the README.
What v15 needs on top:
| v15 change | What this PR does |
| --- | --- |
| No locale JSON files; keys are namespaced with inline English | v14's
12 locale files are dropped. "What it sends" is
`aiComponents.toolApproval.arguments.label` (the `<summary>`) and
`aiComponents.toolApproval.arguments.ariaLabel` (the group's label).
`keys.ts` and `catalog.fixture.json` regenerated. |
| Hand-reviewed v14 to v15 key map | `ai-docs/i18n-v15-key-map.json`
maps "What it sends" to both keys (count 661). |
| Strict example dictionaries | The vite example's `de` and `it`
dictionaries get both keys, with v14's translations. |
| Tests render without `renderWithEnglish` | The new tests in
`AIMessagePartViews`, `AIConversationUI` and `A2UIRenderer` use
`render`. |
| stream-chat v10 | `examples/ai-ui-gallery` takes no `stream-chat`
dependency of its own (the AI entries import none at runtime, and its
own copy would install a second `@stream-io/state-store`), its fixture
replies keep `ai_generated` / `ai_ui` under `custom`, and it drops its
hand-rolled `TranslationProvider`, since the default translator renders
each call site's inline English outside `<Chat>` (its `t` would have
shown the dotted keys). |
| CI and scripts on `master` | `package.json` keeps `api-surface` next
to the new `validate-ai-ui-tokens` and `start:ai-ui-gallery`. CI keeps
master's `keys.ts` drift check and example builds, and runs `yarn
validate-ai-ui-tokens` after the entry-isolation check; the examples
comment lists the gallery. `AGENTS.md` lists the gallery, its start
script and the new check. |
| The cookbook owns port 5176 on `master` | The gallery serves on 5177
with `--strictPort`, and its screenshot script defaults to it. |
| Docs that count or list keys | The plugin README's key table and the
migration guide's row count (661) include the new keys. |
Checks: `yarn test` (3849 passing), `tsc -p tsconfig.lib.json --noEmit`,
`yarn types:scripts`, `yarn lint`, `yarn build`, `validate-cjs`,
`validate-esm`, `validate-entry-isolation`, `validate-translations`,
`validate-ai-ui-tokens` (no colour left unset, 21 A2UI components
checked), and the ai-ui-gallery, vite, tutorial and cookbook example
builds. The Next.js ai-chatbot build stops on Next.js's npm
security-advisory gate, as on #3399; this PR does not touch that
example. The gallery's Playwright contrast screenshots were not re-run
on v15.
### UI Changes
The same as #3399: A2UI and OpenUI replies take the AI tokens and reach
4.5:1 contrast in every gallery cell, approval cards show the call's
arguments, and a reply with neither UI nor words can show a fallback.
The before and after screenshots on #3399 apply.
## [15.0.0-rc.4](v15.0.0-rc.3...v15.0.0-rc.4) (2026-11-06)
### β BREAKING CHANGES
* props and ComponentContext keys that had no effect are removed, nine slots are typed without props, and overrides of several slots render in more places.
- `additionalMessageComposerProps` is removed from `Message`, `MessageList`, `VirtualizedMessageList` and `VirtuosoContext`. It did nothing in v14; delete it. If the props were meant for the composer, pass them to the `MessageComposer` you render.
- `MessageReactions.reverse`, `MessageReactionsDetail.sort` and `MessageReactionsDetail.dialogId` are removed, and `MessageUI` no longer passes `reverse` to a `MessageReactions` override. Order reaction types with `sortReactions` and reacting users with `reactionDetailsSort`; the detail's dialog id is `MessageReactionsDetail.getDialogId({ messageId })`.
- `MessageComposer` no longer takes `emojiSearchIndex` or `parent`, the `emojiSearchIndex` override key is removed, and `useMessageComposerContext()` no longer returns `emojiSearchIndex`, `parent` or `audioRecordingConfig`. For emoji autocomplete, register `createTextComposerEmojiMiddleware(SearchIndex)` from `stream-chat-react/emojis` in a `client.config.setSetupFunction('messageComposer', ...)`.
- `WithDragAndDropUpload.acceptedFiles` is removed. Set the accepted types on the composer config, `attachments.acceptedFiles`.
- `ChannelListItem.activeChannel` is removed. A custom `ChannelListItemUI` reads `active`, or compares the app's own selected channel with its `channel`.
- `ChatView.entityInferrers`, the `ChatViewEntityInferer` type and `useChatViewContext().entityInferers` are removed.
- The `AttachmentPreviewList`, `MessageComposerUI`, `MessageEditedIndicator`, `MessageStatus`, `NotificationAnnouncer`, `QuotedMessagePreview`, `SearchSourceResultList`, `TextareaComposer` and `VoiceRecordingPreviewSlot` slots are typed `React.ComponentType` without props, because the SDK renders them without props. Rendering one from `useComponentContext()` with props, or an override with required props, no longer compiles; render the exported component with its props inside the override.
- Overrides of `FileDragAndDropContent`, `BaseImage`, `LoadingIndicator`, `Timestamp`, `Avatar`, `DateSeparator`, `Gallery` and `FileSizeIndicator` now also render where the SDK rendered the default directly: link previews, video thumbnails, galleries, quoted messages, load-more buttons, poll vote lists, thread list items, user search results, the thread's parent message, composer previews and channel detail lists. To keep the default in one place, wrap it in `WithComponents` with the exported default.
See ai-docs/v15-breaking-changes.md (BC-105 to BC-109, BC-033) and ai-docs/ai-migration-v14-v15.md.
* **ChannelListHeader:** ComponentContext.HeaderEndContent is removed. Pass the content
as EndContent to ChannelListHeader / ThreadListHeader instead, by registering a
component that renders the header with it under the ChannelListHeader or
ThreadListHeader key. One component no longer fills both headers.
* **ChannelListHeader:** list-header content renders whenever it is set. HeaderEndContent
showed only while a channel (channel list) or a thread (thread list) was open;
content that should keep that behavior returns null while
useWorkspaceNavigation().openChannels / openThreads is empty. See BC-099 in
ai-docs/v15-breaking-changes.md and "List headers: HeaderEndContent becomes an
EndContent prop" in ai-docs/ai-migration-v14-v15.md.
* **ChannelDetail:** ChannelMembersHeaderActionItem.component is renamed to
Component, matching the message and channel-list action sets.
* **ChannelDetail:** the 'menu' placement of a channel members header action is
renamed to 'dropdown'. A 'menu' item is no longer rendered.
* **ChannelDetail:** the HeaderActionsMenuTrigger prop (on ChannelMembersView and
ChannelMembersHeaderActionsProps), DefaultHeaderActionsMenuTrigger and
ChannelMembersHeaderActionsMenuTriggerProps are removed. The menu trigger is a
{ Component, placement: 'quick-dropdown-toggle' } item in headerActionSet: a
forwardRef button that receives the ref the menu anchors to, aria-expanded and
onClick, and spreads them. defaultChannelMembersHeaderActionSet starts with
DefaultChannelMembersHeaderActions.QuickDropdownToggle; a set without a toggle
item renders no dropdown menu.
* **ChannelDetail:** dropdown header actions no longer receive a closeMenu prop.
They read closeMenu from useContextMenuContext().
* **ChannelDetail:** a header action's filter is renamed to isVisible, typed with
ChannelMembersHeaderActionVisibilityFilterParams and called with { channel }, as
on message actions. A leftover filter is ignored, so the action it hid shows to
every user.
* **ChannelDetail:** ChannelMembersHeaderActionItem is a union whose
quick-dropdown-toggle member has no type or isVisible, and
ChannelMembersHeaderActionPlacement includes 'quick-dropdown-toggle'. Narrow an
item (e.g. 'type' in item) before reading type.
* **ChannelDetail:** a custom HeaderActions renders the set's quick-dropdown-toggle
item itself and filters the set with useBaseChannelMembersHeaderActionSetFilter.
It renders the dropdown items in a ContextMenu opened with
useDialogOnNearestManager, using an id unique to the component instance. See
BC-098 in ai-docs/v15-breaking-changes.md and "The channel members header action
set uses the shared action names" in ai-docs/ai-migration-v14-v15.md.
* **TypingIndicator:** translations of `typing.twoUsers` must use
`{{ firstUser }}` and `{{ secondUser }}` instead of `{{ typing }}`, for example
'{{ firstUser }} und {{ secondUser }} schreiben'. A translation that keeps
`{{ typing }}` still compiles but shows the literal text `{{ typing }}`.
See BC-100 in ai-docs/v15-breaking-changes.md and "Keys whose values changed"
in ai-docs/i18n-v15-migration.md.
* unused exports and the transliterate dependency are removed, and stream-chat-react now types channel custom data for apps.
- `Root` and `Header` are no longer exported from the package root. They are the parts of `Alert`; use `Alert.Root` and `Alert.Header`.
- `UploadIcon`, `BinIcon`, `PauseIcon` and `PlayIcon` are removed. Copy the SVG into the app, or use `IconPlus` / `IconAttachment`, `IconDelete`, `IconPauseFill` and `IconPlayFill` from the v15 icon set.
- `@stream-io/transliterate` is no longer an optional dependency. Apps that import it must add it to their own dependencies. For mention search, pass a `transliterate` function to stream-chat's mentions middleware.
- Importing `stream-chat-react` now types `channel.data.custom.name` and `.image` (`string | undefined`). Delete the app's own `name` / `image` declarations on `CustomChannelData`; a declaration with another type overrides the SDK's under `skipLibCheck` and fails with TS2430 without it.
- `DefaultChannelData` no longer has `subtitle` or `team`. Declare them on `CustomChannelData` if the app stores them under `custom`; read the channel's team from `channel.data.team`.
- The translation key `messageComposer.icons.attachFiles.text` is removed.
See ai-docs/v15-breaking-changes.md (BC-101) and ai-docs/ai-migration-v14-v15.md.
* **Message:** Removed the initialMessage property from message props and context. Use the new hook to identify thread-parent messages.
* **ChannelDetail:** outside a modal, the ChannelDetail views render no close
button unless ChannelDetail or ChannelDetailProvider gets onClose. They used to
render a close button that did nothing.
* **ChannelDetail:** ChannelDetail calls onLayoutChange on every layout change. It
used to ignore the prop.
* **AttachmentSelector:** SimpleAttachmentSelector, and the plain upload button AttachmentSelector renders when File is its only action, follow the composer's File rule instead of the upload-file capability alone. They appear without upload-file when attachments.customCdn is set, are hidden when attachments are disabled (the channel type's uploads flag is off without customCdn, or the client sets attachments.enabled: false), and are disabled once the message holds maxNumberOfFilesPerMessage files. At that limit the menu's File item also stays, disabled, where v14 hid it. See BC-065 in ai-docs/v15-breaking-changes.md and "Attachment and poll availability" in ai-docs/ai-migration-v14-v15.md.
* deprecated message, mention and list APIs are removed.
- `renderText(text, mentionedUsers, options)` is now `renderText(text, options)`, and `RenderTextFunction` is `(text, options)`. Pass mentions as `options.messageMentionEntities`, built with `getRenderTextMentionEntities(message)`.
- Custom mention renderers get `node.mentionedEntity` instead of `node.mentionedUser`.
- `onMentionsClick` / `onMentionsHover` are called with `(event, message)`; the `mentioned_users` argument and the `MentionedUserEventHandler` type are removed (use `CustomMentionHandler`). Read the clicked mention from the target's `data-user-id` / `data-mention-id`.
- `MessageContextValue.onMentionsClickMessage` / `onMentionsHoverMessage` and the handlers from `useMentionsHandler` are `undefined` unless `onMentionsClick` / `onMentionsHover` is passed. Mentions are interactive only when a click handler is set.
- `mentionsMarkdownPlugin` and `createMentionPluginAndDisplayTextSet` take mention entities only, not `UserResponse[]`.
- `useUserRole` is renamed `useMessagePermissions(message)`, and it no longer returns `isAdmin`, `isModerator` or `isOwner`; gate on the `can*` flags or `useChannelCapabilities()`.
- `disableQuotedMessages` is removed from `MessageList`, `Message` and `useMessagePermissions`. To hide quoting, pass a `messageActionSet` without the `quote` item through the `MessageActions` slot.
- `VirtualizedMessageList` drops `defaultItemHeight`, `overscan` and `scrollSeekPlaceHolder`; pass them through `additionalVirtuosoProps`.
- `PinEnabledUserRoles` and `PinPermissions` are removed; use `useMessagePermissions(message).canPin`.
See ai-docs/v15-breaking-changes.md (BC-087 to BC-095) and ai-docs/ai-migration-v14-v15.md.
* message context and grouping API changes.
- MessageProps.threadList and MessageContextValue.threadList are removed. Detect a thread
with `!!useThreadContext()`.
- ReactionSelector.getDialogId takes only `{ messageId }`; the reaction selector dialog id
no longer has a `-thread` part. Each message list has its own dialog manager.
- MessageContextValue.endOfGroup, firstOfGroup and groupedByUser are removed. Read
`useMessageContext().groupStyles[0]` (`top`, `middle`, `bottom` or `single`).
- The str-chat__virtual-message__wrapper--end, --first and --group classes are no longer
applied. Target the list item's .str-chat__li--top / --middle / --bottom / --single.
- MessageList.noGroupByUser and VirtualizedMessageList.shouldGroupByUser are replaced by
groupByUser (defaults: true and false). VirtuosoContext.shouldGroupByUser is groupByUser.
- The groupStyles function prop of both lists is renamed getGroupStyles and is called with
one GetGroupStylesParams object: { groupByUser, maxTimeBetweenGroupedMessages, message,
nextMessage, previousMessage }. The exported getGroupStyles takes the same object, and
useEnrichedMessages takes getGroupStyles and groupByUser instead of groupStyles and
noGroupByUser.
See BC-048, BC-085 and BC-086 in ai-docs/v15-breaking-changes.md.
* **MessageComposer:** useUserRole(message).canEdit is now the update permission alone
(update-any-message, or update-own-message on the user's own message). It no
longer excludes poll messages and giphies. A custom UI that gated an edit button
on it and wants that rule adds `!message.poll_id && message.command !== 'giphy'`.
* **MessageComposer:** the edit, copyMessageText and download rules about the message
moved from useBaseMessageActionSetFilter onto the items of
defaultMessageActionSet as isVisible. A hand-written edit, copyMessageText or
download item without isVisible now shows wherever the base filter allows it,
e.g. edit on a poll message the user may update. Copy the default item's
isVisible to keep the rule. Item isVisible rules also apply when
disableBaseMessageActionSetFilter is set, which previously returned the set
unfiltered, and to failed messages: a poll message or giphy that failed to send
for a network reason no longer offers Edit.
* **MessageComposer:** a message with a poll renders its text and attachments too, and
the quoted message now renders above the poll instead of below it. Such a
message gets str-chat__message--has-poll and no longer gets
str-chat__message--has-single-attachment.
* **MessageComposer:** custom AttachmentPreviewList, VoiceRecordingPreviewSlot and
LinkPreviewList components mount only while their item in
defaultMessageComposerPreviewSet is visible: attachments while the composer holds
an attachment other than a voice recording, voiceRecording while it holds a voice
recording, linkPreviews while a link preview is loading or loaded. Previously they
mounted whenever the preview area showed. A custom component that also renders
something else (a location, a poll, an empty or upload state) replaces its item
with one whose isVisible covers it.

## [15.0.0](https://github.com/GetStream/stream-chat-react/compare/v14.12.0...v15.0.0) (2026-11-06)
### β BREAKING CHANGES
* props and ComponentContext keys that had no effect are removed, nine slots are typed without props, and overrides of several slots render in more places.
- `additionalMessageComposerProps` is removed from `Message`, `MessageList`, `VirtualizedMessageList` and `VirtuosoContext`. It did nothing in v14; delete it. If the props were meant for the composer, pass them to the `MessageComposer` you render.
- `MessageReactions.reverse`, `MessageReactionsDetail.sort` and `MessageReactionsDetail.dialogId` are removed, and `MessageUI` no longer passes `reverse` to a `MessageReactions` override. Order reaction types with `sortReactions` and reacting users with `reactionDetailsSort`; the detail's dialog id is `MessageReactionsDetail.getDialogId({ messageId })`.
- `MessageComposer` no longer takes `emojiSearchIndex` or `parent`, the `emojiSearchIndex` override key is removed, and `useMessageComposerContext()` no longer returns `emojiSearchIndex`, `parent` or `audioRecordingConfig`. For emoji autocomplete, register `createTextComposerEmojiMiddleware(SearchIndex)` from `stream-chat-react/emojis` in a `client.config.setSetupFunction('messageComposer', ...)`.
- `WithDragAndDropUpload.acceptedFiles` is removed. Set the accepted types on the composer config, `attachments.acceptedFiles`.
- `ChannelListItem.activeChannel` is removed. A custom `ChannelListItemUI` reads `active`, or compares the app's own selected channel with its `channel`.
- `ChatView.entityInferrers`, the `ChatViewEntityInferer` type and `useChatViewContext().entityInferers` are removed.
- The `AttachmentPreviewList`, `MessageComposerUI`, `MessageEditedIndicator`, `MessageStatus`, `NotificationAnnouncer`, `QuotedMessagePreview`, `SearchSourceResultList`, `TextareaComposer` and `VoiceRecordingPreviewSlot` slots are typed `React.ComponentType` without props, because the SDK renders them without props. Rendering one from `useComponentContext()` with props, or an override with required props, no longer compiles; render the exported component with its props inside the override.
- Overrides of `FileDragAndDropContent`, `BaseImage`, `LoadingIndicator`, `Timestamp`, `Avatar`, `DateSeparator`, `Gallery` and `FileSizeIndicator` now also render where the SDK rendered the default directly: link previews, video thumbnails, galleries, quoted messages, load-more buttons, poll vote lists, thread list items, user search results, the thread's parent message, composer previews and channel detail lists. To keep the default in one place, wrap it in `WithComponents` with the exported default.
See ai-docs/v15-breaking-changes.md (BC-105 to BC-109, BC-033) and ai-docs/ai-migration-v14-v15.md.
* **ChannelListHeader:** ComponentContext.HeaderEndContent is removed. Pass the content
as EndContent to ChannelListHeader / ThreadListHeader instead, by registering a
component that renders the header with it under the ChannelListHeader or
ThreadListHeader key. One component no longer fills both headers.
* **ChannelListHeader:** list-header content renders whenever it is set. HeaderEndContent
showed only while a channel (channel list) or a thread (thread list) was open;
content that should keep that behavior returns null while
useWorkspaceNavigation().openChannels / openThreads is empty. See BC-099 in
ai-docs/v15-breaking-changes.md and "List headers: HeaderEndContent becomes an
EndContent prop" in ai-docs/ai-migration-v14-v15.md.
* **ChannelDetail:** ChannelMembersHeaderActionItem.component is renamed to
Component, matching the message and channel-list action sets.
* **ChannelDetail:** the 'menu' placement of a channel members header action is
renamed to 'dropdown'. A 'menu' item is no longer rendered.
* **ChannelDetail:** the HeaderActionsMenuTrigger prop (on ChannelMembersView and
ChannelMembersHeaderActionsProps), DefaultHeaderActionsMenuTrigger and
ChannelMembersHeaderActionsMenuTriggerProps are removed. The menu trigger is a
{ Component, placement: 'quick-dropdown-toggle' } item in headerActionSet: a
forwardRef button that receives the ref the menu anchors to, aria-expanded and
onClick, and spreads them. defaultChannelMembersHeaderActionSet starts with
DefaultChannelMembersHeaderActions.QuickDropdownToggle; a set without a toggle
item renders no dropdown menu.
* **ChannelDetail:** dropdown header actions no longer receive a closeMenu prop.
They read closeMenu from useContextMenuContext().
* **ChannelDetail:** a header action's filter is renamed to isVisible, typed with
ChannelMembersHeaderActionVisibilityFilterParams and called with { channel }, as
on message actions. A leftover filter is ignored, so the action it hid shows to
every user.
* **ChannelDetail:** ChannelMembersHeaderActionItem is a union whose
quick-dropdown-toggle member has no type or isVisible, and
ChannelMembersHeaderActionPlacement includes 'quick-dropdown-toggle'. Narrow an
item (e.g. 'type' in item) before reading type.
* **ChannelDetail:** a custom HeaderActions renders the set's quick-dropdown-toggle
item itself and filters the set with useBaseChannelMembersHeaderActionSetFilter.
It renders the dropdown items in a ContextMenu opened with
useDialogOnNearestManager, using an id unique to the component instance. See
BC-098 in ai-docs/v15-breaking-changes.md and "The channel members header action
set uses the shared action names" in ai-docs/ai-migration-v14-v15.md.
* **TypingIndicator:** translations of `typing.twoUsers` must use
`{{ firstUser }}` and `{{ secondUser }}` instead of `{{ typing }}`, for example
'{{ firstUser }} und {{ secondUser }} schreiben'. A translation that keeps
`{{ typing }}` still compiles but shows the literal text `{{ typing }}`.
See BC-100 in ai-docs/v15-breaking-changes.md and "Keys whose values changed"
in ai-docs/i18n-v15-migration.md.
* unused exports and the transliterate dependency are removed, and stream-chat-react now types channel custom data for apps.
- `Root` and `Header` are no longer exported from the package root. They are the parts of `Alert`; use `Alert.Root` and `Alert.Header`.
- `UploadIcon`, `BinIcon`, `PauseIcon` and `PlayIcon` are removed. Copy the SVG into the app, or use `IconPlus` / `IconAttachment`, `IconDelete`, `IconPauseFill` and `IconPlayFill` from the v15 icon set.
- `@stream-io/transliterate` is no longer an optional dependency. Apps that import it must add it to their own dependencies. For mention search, pass a `transliterate` function to stream-chat's mentions middleware.
- Importing `stream-chat-react` now types `channel.data.custom.name` and `.image` (`string | undefined`). Delete the app's own `name` / `image` declarations on `CustomChannelData`; a declaration with another type overrides the SDK's under `skipLibCheck` and fails with TS2430 without it.
- `DefaultChannelData` no longer has `subtitle` or `team`. Declare them on `CustomChannelData` if the app stores them under `custom`; read the channel's team from `channel.data.team`.
- The translation key `messageComposer.icons.attachFiles.text` is removed.
See ai-docs/v15-breaking-changes.md (BC-101) and ai-docs/ai-migration-v14-v15.md.
* **Message:** Removed the initialMessage property from message props and context. Use the new hook to identify thread-parent messages.
* **ChannelDetail:** outside a modal, the ChannelDetail views render no close
button unless ChannelDetail or ChannelDetailProvider gets onClose. They used to
render a close button that did nothing.
* **ChannelDetail:** ChannelDetail calls onLayoutChange on every layout change. It
used to ignore the prop.
* **AttachmentSelector:** SimpleAttachmentSelector, and the plain upload button AttachmentSelector renders when File is its only action, follow the composer's File rule instead of the upload-file capability alone. They appear without upload-file when attachments.customCdn is set, are hidden when attachments are disabled (the channel type's uploads flag is off without customCdn, or the client sets attachments.enabled: false), and are disabled once the message holds maxNumberOfFilesPerMessage files. At that limit the menu's File item also stays, disabled, where v14 hid it. See BC-065 in ai-docs/v15-breaking-changes.md and "Attachment and poll availability" in ai-docs/ai-migration-v14-v15.md.
* deprecated message, mention and list APIs are removed.
- `renderText(text, mentionedUsers, options)` is now `renderText(text, options)`, and `RenderTextFunction` is `(text, options)`. Pass mentions as `options.messageMentionEntities`, built with `getRenderTextMentionEntities(message)`.
- Custom mention renderers get `node.mentionedEntity` instead of `node.mentionedUser`.
- `onMentionsClick` / `onMentionsHover` are called with `(event, message)`; the `mentioned_users` argument and the `MentionedUserEventHandler` type are removed (use `CustomMentionHandler`). Read the clicked mention from the target's `data-user-id` / `data-mention-id`.
- `MessageContextValue.onMentionsClickMessage` / `onMentionsHoverMessage` and the handlers from `useMentionsHandler` are `undefined` unless `onMentionsClick` / `onMentionsHover` is passed. Mentions are interactive only when a click handler is set.
- `mentionsMarkdownPlugin` and `createMentionPluginAndDisplayTextSet` take mention entities only, not `UserResponse[]`.
- `useUserRole` is renamed `useMessagePermissions(message)`, and it no longer returns `isAdmin`, `isModerator` or `isOwner`; gate on the `can*` flags or `useChannelCapabilities()`.
- `disableQuotedMessages` is removed from `MessageList`, `Message` and `useMessagePermissions`. To hide quoting, pass a `messageActionSet` without the `quote` item through the `MessageActions` slot.
- `VirtualizedMessageList` drops `defaultItemHeight`, `overscan` and `scrollSeekPlaceHolder`; pass them through `additionalVirtuosoProps`.
- `PinEnabledUserRoles` and `PinPermissions` are removed; use `useMessagePermissions(message).canPin`.
See ai-docs/v15-breaking-changes.md (BC-087 to BC-095) and ai-docs/ai-migration-v14-v15.md.
* message context and grouping API changes.
- MessageProps.threadList and MessageContextValue.threadList are removed. Detect a thread
with `!!useThreadContext()`.
- ReactionSelector.getDialogId takes only `{ messageId }`; the reaction selector dialog id
no longer has a `-thread` part. Each message list has its own dialog manager.
- MessageContextValue.endOfGroup, firstOfGroup and groupedByUser are removed. Read
`useMessageContext().groupStyles[0]` (`top`, `middle`, `bottom` or `single`).
- The str-chat__virtual-message__wrapper--end, --first and --group classes are no longer
applied. Target the list item's .str-chat__li--top / --middle / --bottom / --single.
- MessageList.noGroupByUser and VirtualizedMessageList.shouldGroupByUser are replaced by
groupByUser (defaults: true and false). VirtuosoContext.shouldGroupByUser is groupByUser.
- The groupStyles function prop of both lists is renamed getGroupStyles and is called with
one GetGroupStylesParams object: { groupByUser, maxTimeBetweenGroupedMessages, message,
nextMessage, previousMessage }. The exported getGroupStyles takes the same object, and
useEnrichedMessages takes getGroupStyles and groupByUser instead of groupStyles and
noGroupByUser.
See BC-048, BC-085 and BC-086 in ai-docs/v15-breaking-changes.md.
* **MessageComposer:** useUserRole(message).canEdit is now the update permission alone
(update-any-message, or update-own-message on the user's own message). It no
longer excludes poll messages and giphies. A custom UI that gated an edit button
on it and wants that rule adds `!message.poll_id && message.command !== 'giphy'`.
* **MessageComposer:** the edit, copyMessageText and download rules about the message
moved from useBaseMessageActionSetFilter onto the items of
defaultMessageActionSet as isVisible. A hand-written edit, copyMessageText or
download item without isVisible now shows wherever the base filter allows it,
e.g. edit on a poll message the user may update. Copy the default item's
isVisible to keep the rule. Item isVisible rules also apply when
disableBaseMessageActionSetFilter is set, which previously returned the set
unfiltered, and to failed messages: a poll message or giphy that failed to send
for a network reason no longer offers Edit.
* **MessageComposer:** a message with a poll renders its text and attachments too, and
the quoted message now renders above the poll instead of below it. Such a
message gets str-chat__message--has-poll and no longer gets
str-chat__message--has-single-attachment.
* **MessageComposer:** custom AttachmentPreviewList, VoiceRecordingPreviewSlot and
LinkPreviewList components mount only while their item in
defaultMessageComposerPreviewSet is visible: attachments while the composer holds
an attachment other than a voice recording, voiceRecording while it holds a voice
recording, linkPreviews while a link preview is loading or loaded. Previously they
mounted whenever the preview area showed. A custom component that also renders
something else (a location, a poll, an empty or upload state) replaces its item
with one whose isVisible covers it.
* channel.watch() resolves with the channel instance to use (the channel, or the instance that superseded it), not the server response: read channel.data, channel.state and channel.messagePaginator instead.
- channel.watch() sends no query for a channel already watched and loaded unless it asks for options the current watch was not sent with, so it no longer refreshes one: refresh with channel.reload(), load other messages through channel.messagePaginator.
- A channel.watch() while another with the same options is in flight joins it instead of sending a request.
* **MessageList:** useMessageListScrollManager no longer takes onScrollToTop. Loading older messages keeps the message the reader was looking at in place, also when loading starts at the very top, instead of pinning the newly loaded page to the top.
- InfiniteScrollPaginator's loadNextDebounceMs now rate-limits the edge check while scrolling (the first check runs at once, then at most once per loadNextDebounceMs) instead of waiting until scrolling stops for that long. Older and newer pages start loading before the reader reaches the edge.
- MessageList and VirtualizedMessageList pass showNotification to NewMessageNotification only when a message from someone else arrives while the list is scrolled up. Being on an older message set no longer shows it; ScrollToLatestMessageButton signals that.
- In a channel, ScrollToLatestMessageButton shows the current user's unread count from the channel's read state instead of counting message.new events, so messages a reconnect brought in are included. In a thread it counts new replies from 0.
* marker: the removals are v14 API, so the branch has a
`fix!:` commit with a `BREAKING CHANGE:` footer, per the AGENTS.md
convention. The footer to keep in the squash commit:
* `MessageList` no longer accepts `messages`, `hasMore`,
`jumpToLatestMessage`, `loadingMoreNewer` or `messageLimit`, and
`VirtualizedMessageList` no longer accepts `messages`; the lists render
and paginate the message paginator. `CustomClasses.chatContainer` and
the `ComponentContext.LoadingErrorIndicator` slot are removed. Inside
`ChatView` the channel list no longer renders its own `str-chat <theme>`
scope. See ai-docs/v15-breaking-changes.md (BC-019, BC-046, BC-047,
BC-073, BC-074).
Verification: `yarn lint`, `tsc -p tsconfig.lib.json --noEmit`, `yarn
types:scripts`, `yarn validate-translations` and `yarn test` (281 files,
3090 tests) pass. `yarn build`, `validate-cjs`, `validate-esm`,
`validate-entry-isolation`, and the tutorial and vite example builds
passed before the rebase onto the guides branch, which brought in only
docs and the api-surface script. The ai-chatbot example build was not
verified: it hung locally in a sandboxed environment. The theme-scope
change was not checked visually in a browser.
### UI Changes
No intended visual change inside `ChatView`. Outside `ChatView`, the
channel list picks up the design tokens again, as in v14. The
`MessageList` loading indicator now appears while older messages load.
No screenshots: the examples need Stream credentials to run.

<!-- end of auto-generated comment: release notes by coderabbit.ai -->
* the `options` prop of `useCreateChatClient` is renamed to
`config`, and its type changes from `StreamChatOptions` to the `stream-chat`
configuration tree (`DeepPartial<InstanceConfigTree>`). Options that were
passed at the top level now go under the `client` key, for example
`options={{ baseURL, axiosRequestConfig }}` becomes
`config={{ client: { baseURL, axiosRequestConfig } }}`. Requires a
* requires stream-chat 10.0.0-rc.20 or later; client.activeChannels, client.getChannelById() and client.getChannelByMembers() are gone, use client.channelManager.get(cid), values() and client.channel() / client.channelManager.ensure({ type, id, data }); the thread list is client.threads.paginator, and threads come from client.threads.ensure() / get().
* getChannel() is removed; get the channel from client.channelManager.ensure() and call channel.ensureWatched(options).
* channel search results, and the channels message search fetches for its results, are no longer watched; a custom search result component watches the channel when it is opened (channel.ensureWatched(), or jumpToMessage(id, { watchChannel: true }) for a message).
* port the tutorial alignment (#3251) to v15, with panel-aware workspace navigation (#3301)
* **MessageComposer:** the `preventClearingOnUnmount` prop is removed from
`MessageComposer`. Drop it. If you relied on unmounting to clear a
composer supplied through `MessageComposerControllerProvider`, call
`clear()` on it yourself when your UI is done with it.
* `ChannelListItemProps.channelUpdateCount` is removed.
The unread badge now updates without it.
* `ChannelListItemProps.key` is removed. React's own
`key` prop is unaffected.
* `ChannelListItemProps.watchers` is removed. It had no
effect in v15.
* adopt stream-chat's branded TimestampNS (#3297)
* **Attachment:** `useSendMessageFn` and `useUpdateMessageFn` are removed. Call
`messageComposer.send()` and `messageComposer.update()` instead. They resolve
`'sent' | 'nothing-to-send' | 'failed'` rather than a boolean, so a truthiness
check on the result now passes for every outcome β compare against `'sent'`.
* **Attachment:** the two message submission failure notifications changed key.
`messageComposer.sendMessageFn.sendMessageRequestFailed.text` is now
`notification.messageSendFailed`, and
`messageComposer.updateMessageFn.editMessageRequestFailed.text` is now
`notification.messageUpdateFailed`. A typed custom translation dictionary fails
to compile until both are renamed.
* **Attachment:** `RetryHandler` takes `Omit<OperationParams<'retry'>, 'message'>`
instead of `RetrySendMessageWithLocalUpdateParams`, which stream-chat removed in
GetStream/stream-chat-js#1882. Code that names the old type must be updated.
* the `stream-chat` peer range moves to `^10.0.0-rc.12`. That release removes
`connection.changed`, changes `client.wsConnection` from the socket itself to a wrapper, and moves
the socket's settings into configuration. See GetStream/stream-chat-js PR 1859 for the full list;
an application on an earlier `stream-chat` will not typecheck against this version.
* connectivity is read from state stores rather than events. Code that listened for
`connection.changed` β to render its own banner, to refetch on reconnect β must subscribe to
`client.wsConnection.state` or `client.networkConnection.state` instead, or use the new
`useWSConnectionState` / `useNetworkConnectionState` hooks. Nothing in this package dispatches or
forwards the old event. Note the two stores name their fields differently: the socket's `isHealthy`
is always a boolean, while the network's `isOnline` is `boolean | undefined`, where `undefined`
means no platform reporter has reported yet and must be tested with `=== false`.
* `Channel` no longer reloads its channel on `connection.recovered`. The client
reloads every active channel itself and dispatches the event afterwards, so handling it here
reloaded each open channel twice per reconnect. Anything relying on the component to refresh a
channel after a reconnect should rely on the client instead.
* a socket drop on a working network now renders "Reconnectingβ¦" rather than
"Waiting for networkβ¦", from the new `chat.reportLostConnection.reconnecting.text` key. Tests and
dictionaries keyed on the old copy for that case need updating; the `waitingNetwork` key is
unchanged and still used when the device network is down. The delay before either banner appears
now comes from `client.wsConnection.config.offlineNotificationDisplayDelayMs` (5s default) rather
than from a fixed hold inside the client, so changing that config changes when the banner shows.
The `system:network:connection:lost` notification type is unchanged.
* `Thread` requires a `thread` prop and renders `children`.
`additionalMessageComposerProps`, `additionalMessageListProps`,
`additionalParentMessageProps`, `additionalVirtualizedMessageListProps`, `autoFocus` and
`virtualized` are removed β pass those props to the children you render. `Thread`
provides the thread itself, so it no longer needs to be wrapped in `ThreadProvider`. The
`str-chat__thread--virtualized` class is gone; `Thread` cannot know which list you chose.
* `Thread.enableDateSeparator` is removed with nothing in its place. A
`MessageList` in a thread now follows its own default and shows date separators unless
you pass `withDateSeparator={false}`.
* `disableDateSeparator` is renamed to `withDateSeparator` on
`MessageList` (default `true`, was `disableDateSeparator={false}`) and
`VirtualizedMessageList` (default `false`, was `disableDateSeparator={true}`). The rename
also reaches `processMessages`, `useEnrichedMessages`, `FloatingDateSeparator`,
`useFloatingDateSeparator` and `useFloatingDateSeparatorMessageList`.
* the `head` prop is removed from `MessageList` and
`VirtualizedMessageList`. Both render the thread's parent message from context; override
it with a `ThreadHead` component on `ComponentContext`.
* `ThreadHeaderProps` is down to `overrideTitle`. `thread` comes from the
thread in context, and `closeThread` goes through workspace navigation β customize it
centrally via `ChatView`'s `deriveWorkspaceNavigation`, or call the new `useCloseThread()`
hook from a header of your own. `ComponentContext.ThreadHeader` is removed; compose the
header you want.
* `ThreadSlot` wraps its children in `<Thread>` instead of letting them
replace the whole panel, mirroring `ChannelSlot`. Markup that must sit outside the thread
container moves outside `ThreadSlot`; anything needing thread context must sit inside.
* `Thread` no longer rebuilds its subtree when the thread changes. A
custom component rendered inside `Thread` that relied on being remounted per thread β to
reset local state, or to re-run a mount effect β must depend on the thread instead. The
SDK's own message list does this by keying on the thread; `WithAudioPlayback` by taking
`playbackScope`.
* `LegacyThreadContext` and its `legacyThread` value are removed. The
thread composer resolves its composition context from the `Thread` instance in
`ThreadContext`.
* **MessageActions:** the `messageActions` prop is removed from `Channel`,
`MessageList`, `VirtualizedMessageList`, `Thread` and `Message`. Filter
`defaultMessageActionSet` and pass the result as `messageActionSet`
instead.
* **MessageActions:** `MESSAGE_ACTIONS`, `OPTIONAL_MESSAGE_ACTIONS`,
`getMessageActions()`, and the `MessageActionsArray` and `Capabilities`
types are no longer exported. Use the new `DefaultMessageActionType`
union for the action types the SDK ships.
* **MessageActions:** `MessageContext` no longer carries `getMessageActions`
or `actionsEnabled`. The rendered action set is decided by
`messageActionSet` and each item's own `isVisible` predicate.

* **AudioPlayback:** `ChannelProps.allowConcurrentAudioPlayback`,
`ThreadProps.allowConcurrentAudioPlayback` and
`WithAudioPlaybackProps.allowConcurrentPlayback`
are removed, with no replacement. If you passed `true`, delete it:
starting a player now pauses
whichever was playing and takes the shared element over. If you passed
`false` or nothing, the
only change is that playback is exclusive across surfaces rather than
within one.
* **AudioPlayback:** `useActiveAudioPlayer()` now reports the app-wide
active player rather than the
calling surface's.
* **Channel:** `ChannelProps.channel` is now required and
`EmptyPlaceholder` is removed.
Render the exported `ChannelPlaceholder` to fill the same
`.str-chat__channel` layout slot
while no channel is selected.
* **Channel:** `Channel` no longer queries the channel;
`initializeOnMount` and
`channelQueryOptions` are removed. Whoever supplies the channel
initializes it β use the
exported `getChannel({ channel, client })`, which watches and
de-duplicates concurrent calls.
Channels from `ChannelList` or any `queryChannels` call arrive watched
already. `Channel` no
longer renders `LoadingIndicator` or `LoadingErrorIndicator` for a query
it does not make, and
an uninitialized channel renders as an empty channel with no error.
* **Channel:** `Channel` no longer writes `document.title`, and
`activeUnreadHandler` is
removed. See `examples/vite/src/DocumentTitleManager` for a working
replacement in application
code.
* **Channel:** the `channel.channelMissing.text` translation key is
removed. This is a
compile error (TS2353) for any dictionary typed with the exact
`TranslationDictionary` β
delete the entry from custom locale files.
* **Channel:** `ChatContext.latestMessageDatesByChannels` is removed.
Slow-mode cooldown now
lives on `channel.cooldownTimer` (`useCooldownRemaining` /
`useIsCooldownActive`), and the
channel's latest message on
`channel.messagePaginator.aggregateState.lastMessage`.
* **Channel:** `Channel` no longer jumps to a message focused from
search. Selecting a search
result calls `channel.messagePaginator.jumpToMessage(id)` directly, and
the highlight is read
from `channel.messagePaginator.messageFocusSignal`. A custom message
list that relied on
`Channel` performing the jump must call `jumpToMessage` itself.
* **i18n:** consume the shared runtime from @stream-io/i18n (#3284)
* move to timestamps in response models (#3278)
* request-handler props are removed from `Channel` and
`Thread`.
`doSendMessageRequest`, `doUpdateMessageRequest`,
`doDeleteMessageRequest` and
`doMarkReadRequest` are gone, along with `useChannelRequestHandlers`,
`useThreadRequestHandlers` and `useEditMessageHandler`. Register once on
the client:
```
// v14
<Channel channel={channel} doSendMessageRequest={mySend}>
// v15
client.config.set({
channel: {
requestHandlers: {
sendMessageRequest: async ({ localMessage, message, options }) => ({
message: await mySend(message, options),
}),
},
},
});
```
Three differences: handlers take a single params object and return `{
message }`; thread
flows register under the `thread` key; and registration is per CLIENT,
not per mounted
subtree β the one thing the props could do that this cannot. Per-channel
behaviour now
needs a branch inside one handler on the `cid` it receives.
* `useChannelConfig` returns the channel's RESOLVED
configuration instead
of the channel type's raw server config, so field names change:
channelConfig?.typing_events β channelConfig?.typingEvents.enabled
channelConfig?.read_events β channelConfig?.readEvents.enabled
channelConfig?.replies β channelConfig?.replies.enabled
channelConfig?.user_message_reminders β
channelConfig?.userMessageReminders.enabled
channelConfig?.commands β channelConfig?.availableCommands
Every gate is now the server flag ANDed with what is registered through
`client.config`,
which is what the client actually enforces. The hook also subscribes:
these were getters,
so a `client.config.set()` previously never reached the screen. No
component reads
`channel.serverConfig` any more.
* `useAttachmentManagerState` replaces
`hasCustomDoUploadRequest` with
`customCdn`, and gains `attachmentsEnabled`, `locationEnabled` and
`pollsEnabled`.
* the per-domain stores on `channel.state` are removed β
`readStore`,
`typingStore`, `membersStore`, `watcherStore`, `ownCapabilitiesStore`,
`mutedUsersStore`.
Subscribe to `channel.state` itself; the selector is unchanged, because
`ChannelStateData`
is flat and keeps the same top-level keys:
useStateStore(channel.state.ownCapabilitiesStore, sel) β
useStateStore(channel.state, sel)
`WatcherState` is renamed `ChannelWatchState`, and
`channel.disconnected` is renamed
`channel.pendingDisposal` (removed outright β no deprecated alias).
* `AIStates` is no longer exported from
`stream-chat-react` β import it
from `stream-chat`. The values are unchanged, but it is now
literal-typed, so an inferred
array of its members no longer accepts the wide `AIState`:
const STOPPABLE: readonly AIState[] = [AIStates.Thinking,
AIStates.Generating];
* `<Channel>` marks its channel active while mounted and
reloads it on
`connection.recovered`. The client skips re-seeding an active channel's
message list on
hydration and reconnect, so the consumer owns that window. A custom
channel surface that
does not render `<Channel>` must call `channel.activate()` /
`deactivate()` and
`channel.reload()` itself, or its list goes stale after a reconnect.
* **i18n:** adopt the shared i18n layer from stream-chat/i18n (#3271)
* **context:** - **Context hooks no longer accept a `componentName` argument.**
`useChatContext('X')` and friends stop type-checking; drop the argument.
- **Required contexts throw when used outside their provider**, instead
of logging a warning and returning `{}`. Affects the 14 hooks listed
above. Components must be rendered within the provider they read from β
e.g. anything calling `useChatContext` needs a `<Chat>` ancestor.
- **`useChannelInstanceContext` returns
`Partial<ChannelInstanceContextValue>`** β `channel` is now typed as
possibly `undefined`.
- **`ChatViewContext` has no default value** (typed `| undefined`), so
`useContext(ChatViewContext)` may return `undefined`.
- **`MessageComposerContext` is typed as `MessageComposerContextValue |
undefined`**, correcting a narrower declaration that was papered over
with casts.
- **The gallery header no longer uses the
`ComponentContext.MessageTimestamp` override**; it renders the item's
own timestamp.
### π Implementation details
Parameter removed from all 7 hooks and their 138 call sites.
Missing-provider behaviour also normalized, since `src/` had three
competing conventions (warn + `{} as T`, throw, silent cast). The `{} as
T` fallback deferred failures to a downstream `Cannot read properties of
undefined` several frames away. Everything now goes through
`requireContext` (`src/context/requireContext.ts`):
- **Required β throw**, naming hook and provider: `useChatContext`,
`useMessageContext`, `useMessageComposerContext`,
`useMessageListContext`, `useVirtualizedMessageListContext`,
`useMessageBounceContext`, `usePollContext`, `useDialogManager`,
`useSearchContext`, `useSearchSourceResultsContext`,
`useContextMenuContext`, `useChannelListItemContext`,
`useGalleryContext`, `useChatViewContext`
- **Optional by design β keep default, honest type**:
`useTranslationContext`, `useComponentContext`,
`useChannelInstanceContext` (now `Partial`), `useModalContext`,
`useAriaLiveAnnouncer`, `useMessageTranslationViewContext`
- **Renders both inside and outside a provider β read the raw context**:
`Audio`, `VoiceRecording`, `CardAudio`, `Timestamp`,
`MessageRepliesCountButton`, `MessageComposerUI`, `ModalGallery`
Two changes were needed before their hooks could throw:
- `WithDragAndDropUpload` detected the composer via
`Object.keys(ctx).length > 0`; now uses a
`useIsWithinMessageComposerContext()` predicate. Adds the test file this
component lacked.
- `GalleryHeader` read message context while rendering outside any
`MessageProvider`. `GalleryItem` now carries `user` and `createdAt` β
wrapping the call sites would be wrong, since `ChannelMediaView`
flattens many messages into one list. Adds a
`timestamp.GalleryTimestamp` key.
`ChatViewContext` also loses its module-level `LayoutController`
default, which let unrelated subtrees write to one shared instance.
`src/context/__tests__/missingProviderContract.test.tsx` pins the
required/optional split.
### π¨ UI Changes
The channel-media gallery header now shows a per-item sender and
timestamp, which it previously couldn't display at all.
No screenshots: the demo users on the shared environment have no
channels, and seeding one would write test data others would see.
Covered by unit tests in `GalleryUI.test.tsx` β worth a manual look.
* the <Chat> prop and the ChatContext field channelPaginatorsOrchestrator are renamed to channelManager, and the types ChannelPaginatorsOrchestrator / ChannelPaginatorsOrchestratorState are now ChannelManager / ChannelManagerState. Every useChatContext() consumer reading the old field, and any test that builds a partial ChatContext value, has to be updated. No deprecated prop or type aliases are exported.
* requires stream-chat v10.
* Removed `ChannelStateContext` and `ChannelActionContext` along with
`useChannelStateContext()`, `useChannelActionContext()`,
`useCreateChannelStateContext()` and `useCreateChannelActionContext()`.
Read the channel via `useChannel()` and message state via
`useMessagePaginator()`; both are backed by LLC `StateStore`s.
* `ChatContext` no longer exposes the active channel or `setActiveChannel()`.
Channel/thread routing is slot-driven β use `useChatViewNavigation()` from
`stream-chat-react/slot-layout` (`openChannel`, `openThread`, `closeThread`).
* The `TypingContext` provider path was removed from the `Channel` runtime.
`TypingIndicator` now derives its state from LLC stores and takes
`isMessageListScrolledToBottom` and `scrollToBottom` props.
* Context mutation/pagination helpers were replaced by paginator methods:
`updateMessage`/`removeMessage` -> `ingestItem`/`removeItem`;
`loadMore`/`loadMoreNewer` -> `toTail()`/`toHead()`;
`jumpToMessage`/`jumpToFirstUnreadMessage` -> `messagePaginator.jumpToMessage()`/
`jumpToTheFirstUnreadMessage()`. Messages are no longer in `channel.state`.
* Custom send/update/delete/markRead overrides move from ChannelActionContext
callbacks to `channel.configState.requestHandlers` /
`thread.configState.requestHandlers`.
* `ChatView` is a navigation landmark, not a WAI-ARIA Tabs widget: the selector
is `role="navigation"` with `aria-current` on the active button. There is no
`role="tab"`/`"tablist"`/`"tabpanel"`. `activeChatView` renamed to `activeView`.
* `ChannelList` renders a `role="listbox"` whose items are `role="option"`.
* v10 data shapes: channel name/image read from `channel.data.custom.name`/
`.custom.image`; user custom fields from `user.custom` (e.g. `username`);
attachment `duration`/`file_size`/`mime_type`/`waveform_data` from
`attachment.custom`. Message moderation uses `message.moderation`
(`moderation_details` is gone).

π― Goal
Bring generated UI to v15. An agent can answer with UI: the agents router puts a reply's A2UI or OpenUI block in the message's
ai_uifield, and what the person does goes back asai_ui_action. This shipped on v14 in 14.16.0 (#3388);masterdidn't have it yet.π Implementation details
Ports what #3388 added, on top of v15's
ai-components:src/plugins/AIComponents/GenerativeUI/: the format-agnosticAIUIHost, renderer, document, action, component definitions, view, entrance, runtime loader and error boundary, exported fromstream-chat-react/ai-components.AIConversation'suiprop;fromStreamMessagereadsuiDocument.stream-chat-react/a2ui(ESM only;requirethrows saying so) andstream-chat-react/openui, which load@a2ui/web_core+@a2ui/react0.15 and@openuidev/react-lang+react-uithe first time a reply shows them. These are optional~peers;zodmoves to^4.2.0.vite.config.tsentries pluswithoutUnreachableEntries, so each format ships only entries something can load;package.jsonexports andtypesVersions.ai-ui,a2ui,openuiand_ai-ui-iconsstyles inai-components.css; README sections for Generated UI, A2UI and OpenUI.The renderers, generated-UI code and styles match v14 apart from the changes below. The merged
AIConversation.tsxandentries.tsequal v14 plus master's own v15 changes.Adapted to v15:
fromStreamMessagereadsai_uithroughwithCustomFields, so it findscustom.ai_uion a stream-chat v10 message andai_uiat the top level of a message straight from the API, as it doesai_generated. The renderer and conversation tests build replies the v10 way.common.search.ariaLabelandcommon.close.ariaLabelin place of v14's English keys. The filter's placeholder gets its own key,aiComponents.a2ui.choicePickerFilter.placeholder, which is added to the README table andai-docs/i18n-v15-key-map.json.validate-entry-isolationnow also keeps the main andai-componentsentries off the A2UI and OpenUI plugins and their packages; the ESM smoke test importsa2ui.mjsandopenui.mjs; the CJS one requiresopenui.jsand checks thatrequireofa2uisays it is ESM only.utils.isObjectreuses the generated UI's React-freeisRecordrather than duplicating it.yarn dedupekeeps one@floating-ui/react-dom; the new packages otherwise split it, which brokeyarn types.Button, Form, icons, tokens and theming needed no changes: the components and icon names the A2UI renderer uses exist unchanged on v15, and class names stay the same.
Checked locally:
yarn lint,yarn types,yarn types:scripts,yarn test(319 files, 3,676 tests with all three commits),yarn build(leaveskeys.tsas committed),validate-cjs,validate-esm,validate-entry-isolation.examples:build(run as CI does, withNEXT_TELEMETRY_DISABLED=1) builds all four examples; the vite example's German and Italian dictionaries translate the newaiComponents.a2ui.choicePickerFilter.placeholderkey.Also ports #3394
The second commit brings over the v14 follow-up, generated UI parity with iOS and Android: secrets stay on the device, the person's message is what they pressed, tools that change something run only from a tap (
AIUIClientTool.readOnly,runTool'suserInitiated), the app's tools in both formats' instructions and A2UI@call, amediaUrlcheck before media loads, OpenUIQuerycaching, the renderers'instructionsoption, A2UIbasicComponentsoverrides and OpenUIunknown-actionerrors. It applied without conflicts; only its tests changed, to render withrenderinstead of v14'srenderWithEnglish. Behaviour change (as on v14): a tool withoutreadOnly: trueruns only from a tap.Fixes on top of #3394
The third commit fixes three issues #3394 has on v14 too, each with a test that fails without it:
navigator.userActivation, which pressing Enter to send a message also sets. Browsers withoutuserActivationcan now run Mutations from taps.$variableout of an action's context and message when its form also has unbound fields. OpenUI then passes only the form's own values, which don't include the variable.The same fixes for
release-v14are in #3395.π¨ UI Changes
None to existing components. Generated UI renders only with an
AIUIHostpassed toAIConversation, styled as on v14.Summary by CodeRabbit
