Patch Changes

• #4497 ddc40b7 - fix: tolerate reasoning and image content blocks that omit their declared fields (@okisdev)

• #4517 cefcf27 - chore: update dependencies (@okisdev)

• #4515 f5e94b7 - feat: forward onThreadIdChange through the adapter entry hooks (useLangGraphRuntime, useStreamRuntime, useChatRuntime, useAdkRuntime, useOpenCodeRuntime, usePiRuntime). the option already existed on useRemoteThreadListRuntime but every wrapper dropped it, so routing/persistence built on the settled remote thread id never fired from these hooks. only the settled remote id is emitted; the transient __LOCALID_* placeholder is never surfaced.

• #4467 0749c94 - refactor: split the useStreamRuntime file into hooks/types/converter modules and adopt the shared createRuntimeExtras helper (@okisdev)

• #4519 4b4a0fe - fix: type-check the langchain message converter against the current @langchain/langgraph-sdk (return a single converter Message, accept the generative-UI metadata extension, and bind uiMessagesByParent through a memoized callback rather than the converter's metadata channel). no runtime behavior change.

Patch Changes

• #4151 299d448 - chore: drop stale biome-ignore pragmas now that the repo lints with oxlint (@okisdev)

• #4136 4429aa3 - centralize thread-level shared options forwarding across runtime wrapper hooks. follow-up to #4135. (@okisdev)

  new public exports from @assistant-ui/core (re-exported from @assistant-ui/react):

  • ExternalStoreSharedOptions, a typed Pick over ExternalStoreAdapter covering the four thread-level optional fields every wrapper forwards: isDisabled, isSendDisabled, unstable_capabilities, suggestions.
  • pickExternalStoreSharedOptions(options), plucks those four fields from a wider options object. the body uses satisfies Required<...> so adding a key to the type without copying it in the function is a compile error rather than a silent missing-field bug.
  • useExternalStoreSharedOptions(options) (from @assistant-ui/core/react), a memoized variant for wrappers that wrap their store in useMemo. lets the wrapper list a single stable shared reference as a dep instead of enumerating the four fields. same satisfies guard internally so the destructure stays in sync with the type.

  internal: every runtime wrapper hook (useChatRuntime, useAISDKRuntime, useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime) now uses these helpers instead of inlining the conditional spreads added in #4135. each wrapper sheds 20 to 40 lines of duplicated declarations and conditional spreads; future additions to the shared option set propagate through a single edit in pickExternalStoreSharedOptions instead of touching every wrapper. no user-facing behavior change.

• #4175 2dec3ae - chore: update dependencies (@Yonom)

• #4135 e7c2396 - align the runtime wrapper hooks so every distribution forwards the same set of optional adapter-level fields to useExternalStoreRuntime. closes #4134. (@okisdev)

  useChatRuntime and useAISDKRuntime (which already accepted suggestions) gain three new options:

  • isDisabled, disables the composer input entirely.
  • isSendDisabled, keeps the input usable but makes send() a no-op (paired with composer.canSend).
  • unstable_capabilities, per-thread capability overrides (currently { copy?: boolean }).

  useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime gain all four (the three above plus suggestions).

  adapter-level additions, where missing:

  • useChatRuntime / useAISDKRuntime already accepted dictation and voice through the ExternalStoreAdapter adapter shape; this just confirms the typing.
  • useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime now accept dictation and voice in their adapters object and forward them through.
  • useOpenCodeRuntime gains an adapters option for the first time (attachments / speech / dictation / voice / feedback).

  every new field is optional and defaults to the prior behavior, so existing call sites need no changes.

Patch Changes

• #3967 0a0c306 - feat(core, react): add MessagePrimitive.GenerativeUI primitive (@samdickson22)

  A new first-class primitive for rendering agent-described React UI from a JSON spec, with a consumer-provided component allowlist as the security boundary.

  The agent emits a new generative-ui message part containing a tree of components by name; MessagePrimitive.GenerativeUI walks the spec and resolves each name against the registry you pass in. Unknown names throw a typed GenerativeUIRenderError (or invoke the optional Fallback). Composes with MessagePrimitive.Parts via the new components.generativeUI option, and supports streaming partial specs.

  <MessagePrimitive.Parts
    components={{
      generativeUI: { components: { Card, Button } },
    }}
  />

Patch Changes

• #4049 3eaf583 - feat(react-langchain): parity options + send hooks (toward deprecating react-langgraph) (@Yonom)

  • Adds autoCancelPendingToolCalls (default true): when a new user message is submitted while previous tool calls are still pending, automatically submit tool messages cancelling them so the agent's tool-call accounting stays consistent.
  • Adds unstable_allowCancellation: routes the Cancel button to useStream().stop(). On by default; pass false to disable.
  • Adds unstable_threadListAdapter: custom RemoteThreadListAdapter override for self-hosted persistence (takes precedence over cloud).
  • Adds create and delete options, forwarded to the underlying useCloudThreadListAdapter.
  • Adds useLangChainSend() and useLangChainSendCommand() parity helpers for migrating away from useLangGraphSend / useLangGraphSendCommand.
