Chat SDK Files

Minor Changes

• ad90432: Add opt-in selection change events for Select and RadioSelect inputs in Slack modals
• dc2a777: Add TanStack AI support. thread.post(), thread.reply(), and channel.post() accept the stream returned by TanStack's chat(), and the new chat/ai/tanstack subpath provides toTanStackMessages for thread history and createTanStackTools for the Chat SDK toolset. Neither adds a runtime dependency on @tanstack/ai; the tools require zod 4.2 or newer.
• 139d337: Support Vercel Connect in the Teams adapter with lazy app identity resolution and custom webhook verification. Ensure custom Bot Framework and Graph token factories take precedence over client-secret environment variables.

Add Teams to create-chat-sdk --connect and interactive Connect scaffolding, including the helper, connector environment variable, and setup documentation.

• 2e2426d: Add onInstalled and onUninstalled handlers for installation lifecycle events. The Teams adapter emits them for installationUpdate activities, including the add-upgrade and remove-upgrade actions, with a persistable channelId for later proactive messages.

The Teams adapter now sends, edits, deletes, reacts, and types against the service URL encoded in the thread ID instead of the app-wide default, so conversations hosted on regional or sovereign Bot Framework endpoints are reached correctly. An explicit apiUrl still pins every call to that endpoint.

• 8421953: feat(teams): render tables as the Adaptive Card 1.5 Table element

The Teams adapter now renders Table as the native Adaptive Cards Table element instead of a Container of ColumnSets. Teams draws grid lines between cells, sizes columns by relative weight and marks the header row for accessibility. The @chat-adapter/teams/cards subpath emits the same element.

Table gains optional rendering options that only Teams reads: widths (positive integer column weights), verticalAlign (vertical alignment of cell content), gridLines (default true) and gridStyle. Other adapters ignore them. Pass gridLines: false to keep a borderless table.

The chat JSX runtime now forwards align on <Table>, matching fromReactElement.

• 056d883: Allow history.user.maxPerUser and legacy transcripts.maxPerUser to be false to disable count-based history eviction. The default remains 200 entries per user.
• fcdc1c9: Honor an adapter's definitive isMention: false instead of re-detecting mentions from the message text.

An adapter that reads structured platform content reports true or false, and the SDK falls back to matching @username in the text only when the adapter reports nothing. A definitive false now wins, so an adapter can suppress a mention that exists only in text its platform renders literally, such as a code sample. Adapters that previously returned false to mean "not detected" should return undefined instead. Direct messages are unchanged: with no onDirectMessage handler registered they still route to onNewMention.

Adapter changes that follow from the new contract:

• Linear: ordinary comments are left undetermined, so SDK text detection still applies to them.
• Notion: keyword mode leaves comments without a keyword match undetermined instead of reporting false, so @userName in the text still counts.
• X: posts rebuilt from raw or fetched by id are left undetermined instead of reporting false. Only post.mention.create events report true.
• Discord: a real ping, role mention, @everyone, or allowlisted channel reports true; anything else is left undetermined instead of false, so a literal @botname typed in the text still counts as before.

Patch Changes

• f233ffe: Retry initialization after a failed state connection. Once the state adapter (for example Redis) recovers, the next initialize() call or webhook tries again instead of rejecting with the original connection error. Concurrent callers still share one attempt. Adapter initialization failures remain cached until shutdown() so retries cannot restart adapters that are already running or still starting.
• 91683e5: Wait for Telegram polling handlers to settle before advancing update offsets.
• c21ccbc: Add an opt-in webhook option to propagate message, action, and slash command handler errors through waitUntil while preserving default behavior.
