## Summary
- Add `respondAll(responsesById, options)` to the stream controller and
the React/Angular/Svelte/Vue wrappers, resuming multiple interrupts
pending at the same checkpoint in a single `Command({ resume })`. This
is required for runs that pause on several interrupts at once (e.g.
parallel tool-authorization prompts), which sequential `respond()` calls
cannot service.
- Change `respond()` to take an options object (`{ interruptId?,
namespace?, config?, metadata? }`), folding run-level
`config`/`metadata` onto the resumed run so it applies the same
configurable values and metadata a fresh `submit()` would.
- Extend `ThreadStream.respondInput()` to accept a `responses` batch
(mutually exclusive with the single `interrupt_id`/`response`) and clear
all responded interrupts from local state.
- Update the protocol-v2 reference servers (`embed/protocol.mts`,
`protocol/service.mts`) to read the `responses` batch plus
`config`/`metadata` leniently and fold them onto the run servicing
`input.respond`.
- Update docs (interrupts/use-stream) across all framework packages and
add controller tests for batched resume.
## Summary
- `stream.stop()` now cancels the active run server-side by default
(`client.runs.cancel`) before disconnecting the client transport.
- Added `stream.disconnect()` as an alias for `stop({ cancel: false })`
for join/rejoin UIs.
- Introduced `StreamStopOptions` (`{ cancel?: boolean }`) on
`StreamController` and all v1 framework bindings (React, Vue, Svelte,
Angular).
- Updated `use-stream.md` and added controller unit tests for
cancel-on-stop and no-cancel-on-disconnect.
## Summary
- Split tool-call handles by consumer:
- **Client SDK** (`ThreadStream.toolCalls`, subgraph/subagent
projections): `ClientAssembledToolCall` with a promise-only `output`
(resolves on success, rejects on error). Still exported as
`AssembledToolCall` from `@langchain/langgraph-sdk/client` for script
usage.
- **Framework SDKs** (`stream.toolCalls`, `useToolCalls`,
`injectToolCalls`): `AssembledToolCall` with plain reactive fields —
`output: T | null`, `status`, and `error` — updated in place as events
arrive so React/Vue/Svelte/Angular can render from snapshots without
`await`, effects, or Suspense around promises.
- Add generic `AssembledToolCall<TName, TInput, TOutput>` plus
`id`/`args` aliases; point `InferToolCalls` at assembled streaming
handles and add `AssembledToolCallFromTool` (exported as
`ToolCallFromTool` from `@langchain/react`, `@langchain/vue`,
`@langchain/svelte`, and `@langchain/angular`).
- Rework `ToolCallAssembler` around a mutable internal handle and
`toClientAssembledToolCall()` for client projections; framework stores
the reactive handle directly.
- Remove redundant `InferAssembledToolCalls` and deprecated `StateOf`;
wire typed `toolCalls` / selector generics across all four framework
packages.
- Expand and align `createAgent`, `createDeepAgent`, and `langgraph`
type tests across React, Vue, Svelte, and Angular; update examples,
protocol-v2 integration tests, and Vue migration docs.
Aligning with latest Python changes updating endpoints to be:
POST /threads/{thread_id}/stream/events — SSE event stream
POST /threads/{thread_id}/commands — JSON command
WS /threads/{thread_id}/stream/events
for new streaming features.
