refactor!: remove deprecated message APIs before v15 GA - #3387
Builds on #3386 (REACT-1278), which lands first. This PR targets master and includes #3386's commits until that one merges.
🎯 Goal
Remove the APIs that v14 deprecated or that never worked, before v15 GA, and fix the mention, avatar and thread-head behaviour that the removals exposed.
🛠 Implementation details
Removed, with their replacements (each one has an entry in ai-docs/v15-breaking-changes.md and a step in ai-docs/ai-migration-v14-v15.md):
Removed
Use instead
Entry
renderText(text, mentionedUsers, options)
renderText(text, options) with options.messageMentionEntities (getRenderTextMentionEntities(message))
BC-081
node.mentionedUser in custom mention renderers
node.mentionedEntity
BC-082
the mentioned_users argument of onMentionsClick / onMentionsHover, and MentionedUserEventHandler
handlers get (event, message); type them as CustomMentionHandler
PinEnabledUserRoles, PinPermissions (never in v14 stable)
useMessagePermissions(message).canPin
ruled out as a v14 → v15 change
mentionsMarkdownPlugin / createMentionPluginAndDisplayTextSet taking a UserResponse[]
pass mention entities
BC-088
disableQuotedMessages on MessageList / Message, and the second argument of useMessagePermissions
a messageActionSet without the quote item, through the MessageActions slot. The default actions already ignored the flag in v14, so nothing changes on screen
BC-089
Mention, avatar and thread-head behaviour:
Mentions are interactive (pointer cursor, separate focus stop, Enter/Space) only when an onMentionsClick handler is set. useMentionsHandler and the message context's onMentionsClickMessage / onMentionsHoverMessage are undefined without one (BC-087). MessageText marks the interactive case with str-chat__message-text-inner--mentions-clickable.
A message re-renders when a mention handler is added or removed after it first rendered.
Mention and user handlers swapped after a message rendered reach it: they are wrapped with useStableCallback.
showAvatar on MessageList, VirtualizedMessageList or Message now takes effect: Message passes it into MessageContext, where MessageUI reads it, and a change re-renders the message.
The thread's parent message gets the list-wide message props its replies get (useThreadHead(messageProps)), so onMentionsClick, onUserClick, renderText and showAvatar work on it. Only the props that are set are passed.
messageHasMentions(message) is a new export.
Examples: the cookbook recipes and the vite custom message UI treat only replies as thread messages (useThreadContext() and not initialMessage), so the thread's parent keeps its read receipts, status and actions.
Checks:yarn test (3434 tests), yarn types, yarn lint, yarn build, validate-translations, validate-entry-isolation, and type-checks of the vite and cookbook examples all pass. Mention clicks, the thread parent message, VirtualizedMessageList paging and the cookbook recipes were checked in the browser.
Follow-ups:
REACT-1509: mentions with the same display text link to the first matching entity.
additionalMessageComposerProps on MessageList, VirtualizedMessageList and Message is read by no component; removing it needs its own ticket and BC entry.
🎨 UI Changes
Mentions show a pointer cursor only when an onMentionsClick handler is set; otherwise they keep the default cursor.
showAvatar now changes whether a message shows its avatar.
Summary by CodeRabbit
New Features
Message lists now support configurable grouping by sender, with custom group-style options. Message metadata, including status, sender name, timestamps, and edited indicators, remains visible across group positions.
Mention text supports clickable styling when a click handler is configured, and mention handlers can be added or removed as messages update.
Thread replies are distinguished from parent messages for status, receipt, and action display.
Breaking Changes
Message rendering, mention, permissions, and message-list APIs have changed. Several legacy props, role flags, and the useUserRole hook are removed; consult the updated migration guide.
MessageContext declared threadList, firstOfGroup, endOfGroup and
groupedByUser, but no message list set them. groupStyles is now the
single source of grouping, and thread detection is useThreadContext().
- Remove threadList from MessageProps and MessageContextValue.
ReactionSelector.getDialogId takes only { messageId }; each list's own
dialog manager keeps a message's channel and thread dialogs apart.
- Remove endOfGroup, firstOfGroup and groupedByUser from MessageContext
and the str-chat__virtual-message__wrapper--* classes. The default
MessageUI renders the metadata on every message and the
str-chat__li--top/--middle CSS hides it.
- Rename MessageList.noGroupByUser and
VirtualizedMessageList.shouldGroupByUser to groupByUser (defaults
true and false), and the groupStyles function prop to getGroupStyles,
called with one GetGroupStylesParams object.
- Share the group-style loop as getMessageGroupStyles. The virtualized
list now recomputes group styles when a message changes, not only
when the count does.
BREAKING CHANGE: MessageProps.threadList, MessageContextValue.threadList,
endOfGroup, firstOfGroup and groupedByUser are removed, as are the
str-chat__virtual-message__wrapper--* classes. noGroupByUser and
shouldGroupByUser are replaced by groupByUser, the groupStyles prop by
getGroupStyles, and getGroupStyles and useEnrichedMessages take objects
with groupByUser. See BC-079 and BC-080 in ai-docs/v15-breaking-changes.md.
Ticket: https://linear.app/stream/issue/REACT-1278
The cookbook recipes and the vite example read isInThread from
useThreadContext() instead of MessageContext.threadList, and the vite
example passes groupByUser to VirtualizedMessageList.
Remove the APIs that were deprecated in v14, and tidy the mention and
thread-head handling around them.
- renderText(text, options): the mentionedUsers argument is removed;
mentions come from options.messageMentionEntities.
- The Mention node carries mentionedEntity only.
- onMentionsClick / onMentionsHover are called with (event, message);
MentionedUserEventHandler is removed.
- useUserRole is renamed to useMessagePermissions and no longer returns
isAdmin, isModerator or isOwner.
- PinEnabledUserRoles and PinPermissions are removed.
- VirtualizedMessageList drops defaultItemHeight, overscan and
scrollSeekPlaceHolder; pass them through additionalVirtuosoProps.
- mentionsMarkdownPlugin and createMentionPluginAndDisplayTextSet take
mention entities only.
- Mentions are interactive (pointer, focus stop, Enter/Space) only when
onMentionsClick is set; the message-context mention handlers and
useMentionsHandler's handlers are undefined without one.
- The thread's parent message gets the list-wide message props its
replies get, so onMentionsClick and onUserClick work on it.
- Mention and user handlers swapped after a message rendered reach it.
BREAKING CHANGE: see ai-docs/v15-breaking-changes.md and
ai-docs/ai-migration-v14-v15.md for each removed or changed API and its
replacement.
This change updates message grouping, mention rendering and handlers, message permissions, and thread-context handling. It also updates affected examples and tests, and adds v15 breaking-change documentation for the revised APIs.
Changes: Message and message-list API updates

Summary
Grouping and list behavior src/components/MessageList/*, src/components/Message/MessageUI.tsx, src/components/Message/utils.tsx, src/context/MessageContext.tsx, examples/vite/src/ChatLayout/Panels.tsx
Grouping options now use groupByUser and getGroupStyles. New helpers calculate group styles from processed messages and their neighbors. Group metadata renders for all group styles, and list-wide props are passed to thread-head messages.
renderText now receives mention entities through its options object. Mention nodes use mentionedEntity, and click or hover handlers receive the event and message. Unconfigured handlers are undefined; clickable mention styling and wrapper behavior depend on an active click handler.
useMessagePermissions replaces useUserRole; the quote-disable option and role flags were removed. Consumers now use thread context to identify replies, and reaction-selector dialog IDs use only message IDs.
Migration documentation and validation ai-docs/v15-breaking-changes.md, AGENTS.md, src/components/MessageList/__tests__/*, src/components/Message/hooks/__tests__/*
The v15 migration document adds and revises entries for these API changes and updates its evidence references and coverage map. Tests are updated for the new grouping, mention, permissions, and thread-context behavior.

Explanation
The title "refactor!: remove deprecated message APIs before v15 GA" matches the main change. The PR removes APIs deprecated in v14 or nonfunctional, including renderText's mentionedUsers argument, useUserRole, disableQuotedMessages, and several VirtualizedMessageList props. The title is concise and uses the conventional commit form. It does not mention the mention, avatar, or thread-head behavior changes, which is acceptable because the title need not cover every detail.
Full details: Description check
Explanation
The description covers the goal, implementation details, and a UI changes section, so all three template sections are present. It gives a clear removed-to-replacement table with BC entry references, lists behavior changes, names the tests and checks run, and lists follow-ups. The UI Changes section describes the pointer cursor and avatar changes but has no screenshots. The template asks for screenshots, so that gap is minor. The description is mostly complete.
Full details: Docstring Coverage
Explanation
Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 50 files. (9 skipped: 3 unsupported, 6 over the file limit.)

useThreadContext() is set for the thread parent as well as its replies,
so the read-receipt recipe and the vite custom message UI hid the
parent's receipts, status and actions. Treat only replies as thread
messages by also checking MessageContext.initialMessage.

Not changed: all 88 index rows (BC-001 to BC-088) use the same #bc-NNN links with no heading anchors, so the new rows follow the file's convention. Fixing the links means changing the whole index, which is outside this PR.

@MartinCupela Understood. The new rows follow the existing #bc-NNN pattern in ai-docs/v15-breaking-changes.md. The fragment mismatch affects the whole index, not only these ten rows.
I accept leaving that cleanup outside this PR. Would you like me to open a follow-up issue for all 88 index links?
…licked mention
The cookbook custom message UIs treated the thread parent as a reply,
hiding its status, reply count, pin and reply actions; only replies are
thread messages now (useThreadContext() and not initialMessage).
The onMentionsClick migration example reads data-user-id from the
clicked mention instead of opening the first mentioned user, and the
mentionsMarkdownPlugin test builds its entity from the user fixtures.

Enter or Space on the focused message text calls onMentionsClick with
the text element as the target, so no mention is identified. The
example opens a profile from the keyboard only when the message
mentions exactly one user, and the prose says what the target is.
…to the message
disableQuotedMessages is removed from MessageProps, MessageListProps and
useMessagePermissions, whose canQuote is now the quote-message
capability alone. The default message actions never honoured the flag;
hide the Quote action with a messageActionSet instead.
Message now forwards showAvatar into MessageContext, where MessageUI
reads it, and both message memo comparators re-render when it changes.
The migration guide no longer lists additionalMessageComposerProps and
disableQuotedMessages among the props that affect the thread's parent
message.
BREAKING CHANGE: disableQuotedMessages is removed from MessageList and
Message, and useMessagePermissions takes only the message. See BC-089 in
