github-actions[bot]	31261c3be5	chore: version packages (#2558 ) This PR was opened by the [Changesets release](https://github.com/changesets/action) GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## @langchain/langgraph-checkpoint-mongodb@1.4.0 ### Minor Changes - [#1928](https://github.com/langchain-ai/langgraphjs/pull/1928) [`3d7fcea`](https://github.com/langchain-ai/langgraphjs/commit/3d7fcea7d7ea7f1203d24be9df607d5a8e8717bc) Thanks [@Mihailoff](https://github.com/Mihailoff)! - Add TTL support for automatic checkpoint expiration - Add optional `ttl` parameter to MongoDBSaver (value in seconds) - Add `setup()` method to create TTL indexes on collections - Add `upserted_at` timestamp to documents when TTL is enabled - Each write refreshes TTL (expires after inactivity, not creation) ### Patch Changes - [#2556](https://github.com/langchain-ai/langgraphjs/pull/2556) [`bee3c91`](https://github.com/langchain-ai/langgraphjs/commit/bee3c91d0adc315ebde0622d8c4b1fff041c1bfd) Thanks [@mohamedkhaled4053](https://github.com/mohamedkhaled4053)! - Fix `MongoDBSaver.putWrites` throwing `MongoServerError: Invalid BulkOperation, Batch cannot be empty` when called with an empty `writes` array. This is reached by human-in-the-loop / `interrupt()` flows, where a task can complete producing zero channel writes and LangGraph calls `putWrites(config, [], taskId)`. `putWrites` now no-ops on empty writes, matching the behavior of the postgres and sqlite savers (which iterate and naturally skip empty batches). - [#2550](https://github.com/langchain-ai/langgraphjs/pull/2550) [`2b8cc2f`](https://github.com/langchain-ai/langgraphjs/commit/2b8cc2f3fd5c9d3c33b56e013292daf5d936428e) Thanks [@lazydiv](https://github.com/lazydiv)! - feat(checkpoint-mongodb): add setup() to create required indexes ## @langchain/langgraph-api@1.4.0 ### Minor Changes - [#2559](https://github.com/langchain-ai/langgraphjs/pull/2559) [`48cbdd2`](https://github.com/langchain-ai/langgraphjs/commit/48cbdd23fdf29277530f6aa05c397c9902e81206) Thanks [@christian-bromann](https://github.com/christian-bromann)! - feat(langgraph-cli): add `deploy` command for LangSmith Deployment Port the Python CLI's `langgraph deploy` workflow to `@langchain/langgraph-cli`, including local and remote build paths, deployment lifecycle subcommands (`list`, `revisions list`, `delete`, `logs`), and host-backend client utilities with tests. ### Patch Changes - [#2557](https://github.com/langchain-ai/langgraphjs/pull/2557) [`b1e856d`](https://github.com/langchain-ai/langgraphjs/commit/b1e856d987ac16148dc0872d1fecf70e659ef28e) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph-api): preserve non-empty response_metadata on protocol-v2 state messages The protocol-v2 state normalizer stripped `response_metadata` from messages, dropping data that HITL flows rely on — an interrupt's card is carried on `AIMessage.response_metadata` (e.g. `{ cards: ... }`).

Christian Bromann	b1e856d987	feat(sdk): apply state update and goto alongside interrupt resume (#2557 ) ## Summary - Add `update` and `goto` options to `respond()` across the SDK so resolving an interrupt can apply a state update and/or directed jump in the same superstep — mapped to LangGraph's `Command(resume, update, goto)`. The canonical use case is a HITL flow that pushes the interrupt card into state at the moment it answers, committed in one checkpoint with no flicker. - `@langchain/langgraph-sdk`: new `update`/`goto` fields on `StreamRespondAllOptions`, forwarded by `StreamController.respond`/`respondAll`; `@langchain/core` `BaseMessage` instances under the `messagesKey` are serialized to dicts before transport, exactly like `submit()`. - `@langchain/langgraph-api`: forward `update`/`goto` from `input.respond` into the run `Command` in both the protocol service and the embedded server. - `@langchain/react`, `@langchain/vue`, `@langchain/svelte`, `@langchain/angular`: document the new `respond({ update, goto })` capability (incl. `BaseMessage` examples). - Fix: the protocol-v2 state normalizer stripped `response_metadata`, which HITL cards ride on (`AIMessage.response_metadata`); non-empty `response_metadata` is now preserved. - Add React browser tests (`interrupt_card_graph` fixture via `createAgent`) covering the approve and reject paths: the FE-pushed card lands in committed state exactly once and persists through a slow tool execution.	2026-06-22 08:20:15 -07:00

If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated. # Releases ## @langchain/langgraph-checkpoint@1.1.2 ### Patch Changes - [#2544](https://github.com/langchain-ai/langgraphjs/pull/2544) [`4487214`](https://github.com/langchain-ai/langgraphjs/commit/448721449f0801009ba76b03dd2e9c16f900bbba) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): make concurrent DeltaChannel writes deterministic on replay Concurrent same-superstep writes to a `DeltaChannel` could reconstruct from a checkpoint differently than they were applied live, because live execution ordered them by task path while savers replayed them by task id. This fixes that divergence in two complementary ways: - Plain concurrent writes are now applied in the canonical `(task_id, idx)` order on both paths: `_applyWrites` orders them that way live, and the `getDeltaChannelHistory` walk enforces the same order so reconstruction matches live for every saver (Postgres, SQLite, MongoDB, Redis, and custom). - An `Overwrite` now wins its entire super-step: every sibling write in the same step — before AND after the `Overwrite` — is discarded, matching `BinaryOperatorAggregate`. This makes the result independent of the (unstable) ordering of concurrent fan-in writes; previously a plain write that landed after an `Overwrite` in the same step was still folded in. To keep reconstruction in sync with this `Overwrite` rule, any `DeltaChannel` that sees an `Overwrite` in a super-step is now force-snapshotted at the next checkpoint (and, under `"exit"` durability, in the final checkpoint). The post-overwrite value is materialized into `channel_values`, so a cold read seeds from that snapshot and never has to replay across the reset — making live and reconstructed state identical without changing the sparse-replay history shape. These delta-channel APIs remain Beta. - [#2531](https://github.com/langchain-ai/langgraphjs/pull/2531) [`38cfe01`](https://github.com/langchain-ai/langgraphjs/commit/38cfe01ff02490ff6bcc86c66708ef671f2e0d4b) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): forward task metadata and name subagents via lc_agent_name `mapDebugTasks` now forwards filtered user-meaningful task config metadata (including `lc_agent_name`) onto `tasks` stream payloads. The lifecycle transformer uses that metadata to set subagent `graph_name` from `lc_agent_name` and recover `cause: { type: "toolCall", tool_call_id }` from parent tool-dispatch tasks. Adds the shared `EXCLUDED_METADATA_KEYS` constant to `@langchain/langgraph-checkpoint`. Ports langgraph#7928. ## @langchain/langgraph-checkpoint-redis@1.0.10 ### Patch Changes - [#2336](https://github.com/langchain-ai/langgraphjs/pull/2336) [`25907eb`](https://github.com/langchain-ai/langgraphjs/commit/25907eb0be25258c26327c6c68c72bc828ee1cff) Thanks [@MohMaherId](https://github.com/MohMaherId)! - fix(langgraph-checkpoint-redis): persist and reconstruct full `channel_values` across multi-node graphs. `RedisSaver.put()` delta-filters `channel_values` to only the channels written by the current node, but `getTuple()` had no reconstruction logic — unlike `PostgresSaver` — so any multi-node graph whose last node wrote a subset of channels silently lost the others. Each changed channel is now persisted as a version-keyed `checkpoint_blob:` entry in `put()` and missing channels are reconstructed from those blobs on read. `deleteThread()` now also deletes the `checkpoint_blob:` keys. Without this the blobs introduced above would orphan forever (memory growth) and thread deletion would be incomplete, matching `PostgresSaver.deleteThread()` parity. When `ttlConfig.refreshOnRead` is enabled, reads now refresh the TTL of the reconstructed `checkpoint_blob:*` keys alongside the checkpoint key. Otherwise a read would keep the checkpoint alive while the blobs it depends on expired, silently dropping reconstructed channels. On write, `put()` now refreshes the TTL of every blob the checkpoint references (the full `channel_versions` set), not just the channels changed by the current node, so carried-over blobs from earlier nodes expire in lockstep with the checkpoint doc. This write-side refresh is independent of `refreshOnRead`. The per-channel blob writes also now run in parallel. Known limitation: with TTL enabled, a carried-over blob can still be lost if it expires during an idle gap longer than `defaultTTL` (no read or write refreshed it in time). When that happens the channel is left cleanly absent on read rather than erroring. Fully closing this gap (re-persisting expired blobs) is tracked as a follow-up. ## @langchain/langgraph@1.4.3 ### Patch Changes - [#2544](https://github.com/langchain-ai/langgraphjs/pull/2544) [`4487214`](https://github.com/langchain-ai/langgraphjs/commit/448721449f0801009ba76b03dd2e9c16f900bbba) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): make concurrent DeltaChannel writes deterministic on replay Concurrent same-superstep writes to a `DeltaChannel` could reconstruct from a checkpoint differently than they were applied live, because live execution ordered them by task path while savers replayed them by task id. This fixes that divergence in two complementary ways: - Plain concurrent writes are now applied in the canonical `(task_id, idx)` order on both paths: `_applyWrites` orders them that way live, and the `getDeltaChannelHistory` walk enforces the same order so reconstruction matches live for every saver (Postgres, SQLite, MongoDB, Redis, and custom). - An `Overwrite` now wins its entire super-step: every sibling write in the same step — before AND after the `Overwrite` — is discarded, matching `BinaryOperatorAggregate`. This makes the result independent of the (unstable) ordering of concurrent fan-in writes; previously a plain write that landed after an `Overwrite` in the same step was still folded in. To keep reconstruction in sync with this `Overwrite` rule, any `DeltaChannel` that sees an `Overwrite` in a super-step is now force-snapshotted at the next checkpoint (and, under `"exit"` durability, in the final checkpoint). The post-overwrite value is materialized into `channel_values`, so a cold read seeds from that snapshot and never has to replay across the reset — making live and reconstructed state identical without changing the sparse-replay history shape. These delta-channel APIs remain Beta. - [#2531](https://github.com/langchain-ai/langgraphjs/pull/2531) [`38cfe01`](https://github.com/langchain-ai/langgraphjs/commit/38cfe01ff02490ff6bcc86c66708ef671f2e0d4b) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): merge instead of overwrite in `ensureLangGraphConfig` `ensureLangGraphConfig` now per-key merges `callbacks`, `tags`, `metadata`, and `configurable` across configs instead of last-write-wins, so values bound via `.withConfig({...})` survive when a later (e.g. invoke-time) config supplies other keys. The merged dicts are fresh objects, fixing a by-reference mutation of shared base configs. Also drops the now-redundant `combineCallbacks` workaround in `streamEvents`, which double-registered and double-fired graph-bound callbacks. - [#2531](https://github.com/langchain-ai/langgraphjs/pull/2531) [`38cfe01`](https://github.com/langchain-ai/langgraphjs/commit/38cfe01ff02490ff6bcc86c66708ef671f2e0d4b) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): preserve namespace nesting for imperative graph invokes When a compiled graph is invoked from inside another graph's running task (e.g. a tool body calling `subAgent.invoke(...)`), the surrounding task context — including the langgraph-internal nesting keys (`__pregel_read`, `__pregel_stream`, `checkpoint_ns`, the checkpoint map) — is propagated implicitly via `AsyncLocalStorage`. The base `Runnable.stream` calls langchain-core's `ensureConfig`, which replaces the ambient `configurable` wholesale whenever the caller passes its own. Because `createAgent` always supplies a `configurable`, every tool-invoked sub-agent lost those keys, ran as a fresh root run, and had its streamed events flattened to the root namespace instead of nesting under the triggering task. `Pregel.stream` now merges the ambient `configurable` underneath the caller's (caller keys win per-key) when the ambient marks an active task (`__pregel_read` present) but the explicit `configurable` is missing it. Declared subgraph nodes (which already carry their own `__pregel_read`) and top-level runs are unaffected. - [#2537](https://github.com/langchain-ai/langgraphjs/pull/2537) [`be09666`](https://github.com/langchain-ai/langgraphjs/commit/be096663f42fe7ea9355d6c0def4854e657866d8) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): dispatch stream messages handler inline The v3 `messages` handler (`StreamProtocolMessagesHandler`, which powers `run.messages`) only performs a synchronous `push()` onto the run's stream, but its callbacks were dispatched on LangChain's background callback queue (the default `awaitHandlers === false`). A model or tool call inside a nested or parallel task could therefore flush its `messages` chunk _after_ the Pregel loop returned and sealed the stream, where `IterableReadableWritableStream.push` silently drops chunks once closed. This surfaced as empty per-message streams (`sub.messages`) for subagents dispatched in parallel from a single tools step. The handler now sets `awaitHandlers = true` so its callbacks run inline — every push happens during the originating model/chain call while the stream is still open. This avoids the global over-wait, fake-timer deadlock, and error-path unhandled rejections that a blanket `awaitAllCallbacks()` drain before close would have introduced. - [#2531](https://github.com/langchain-ai/langgraphjs/pull/2531) [`38cfe01`](https://github.com/langchain-ai/langgraphjs/commit/38cfe01ff02490ff6bcc86c66708ef671f2e0d4b) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): forward task metadata and name subagents via lc_agent_name `mapDebugTasks` now forwards filtered user-meaningful task config metadata (including `lc_agent_name`) onto `tasks` stream payloads. The lifecycle transformer uses that metadata to set subagent `graph_name` from `lc_agent_name` and recover `cause: { type: "toolCall", tool_call_id }` from parent tool-dispatch tasks. Adds the shared `EXCLUDED_METADATA_KEYS` constant to `@langchain/langgraph-checkpoint`. Ports langgraph#7928. - [#2549](https://github.com/langchain-ai/langgraphjs/pull/2549) [`bc667a9`](https://github.com/langchain-ai/langgraphjs/commit/bc667a998ae9909d15795387dad45048e8947219) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(langgraph): support DeltaChannel fields in StateSchema Add a `DeltaValue` state field (and a `MessagesDeltaValue` prebuilt) so a `DeltaChannel` can be declared via `StateSchema`, not just `Annotation.Root` or a raw channel map. `StateSchema` now maps `DeltaValue` to a `DeltaChannel` (forwarding `snapshotFrequency` and the value-schema default) and validates its inputs/`Overwrite` updates like `ReducedValue`. -

- Allow custom `AgentServerAdapter`s to be late-bound and re-bound to a thread. Adapters can now implement an optional `setThreadId(threadId)`, which `client.threads.stream(threadId, { transport })` calls when binding the active thread — including the lazily-minted id from the first `submit()` on a `threadId: null` controller. The built-in `ProtocolSseTransportAdapter`, `ProtocolWebSocketTransportAdapter`, and `HttpAgentServerAdapter` implement it: `threadId` is now optional at construction, request URLs derive from the currently-bound thread, and `paths` entries may be functions of the thread id (`(threadId) => string`). This lets a single custom transport back a lazy thread-creation flow instead of being pinned to one thread at construction. - [#2527](https://github.com/langchain-ai/langgraphjs/pull/2527) [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7) Thanks [@christian-bromann](https://github.com/christian-bromann)! - chore(deps): remove uuid dependency in favor of embedded uuid in core Replace direct `uuid` package imports with `@langchain/core/utils/uuid` across langgraph packages to deduplicate dependencies and align with @langchain/core's embedded UUID utilities. ## @langchain/angular@1.0.23 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 ## @langchain/react@1.0.23 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 ## @langchain/svelte@1.0.23 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 ## @langchain/vue@1.0.23 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 ## @example/ai-elements@0.1.38 ### Patch Changes - Updated dependencies \[[`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph@1.4.2 - @langchain/react@1.0.23 ## @examples/assistant-ui-claude@0.1.38 ### Patch Changes - Updated dependencies \[[`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph@1.4.2 - @langchain/react@1.0.23 ## @examples/ui-angular@0.0.48 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 - @langchain/langgraph@1.4.2 - @langchain/angular@1.0.23 ## @examples/ui-multimodal@0.0.24 ### Patch Changes - Updated dependencies \[[`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph@1.4.2 - @langchain/react@1.0.23 ## @examples/ui-react@0.0.24 ### Patch Changes - Updated dependencies \[[`ba31f04`](https://github.com/langchain-ai/langgraphjs/commit/ba31f045d1d458a456c6f6441e8ee81d32c5c700), [`e7e8035`](https://github.com/langchain-ai/langgraphjs/commit/e7e8035fadca5f0d4cbc55bbbb77e65878ab2952), [`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph-sdk@1.9.22 - @langchain/langgraph@1.4.2 - @langchain/react@1.0.23 ## langgraph@1.0.42 ### Patch Changes - Updated dependencies \[[`9e114e5`](https://github.com/langchain-ai/langgraphjs/commit/9e114e55d362a874878a817740de42fd62ae9db7)]: - @langchain/langgraph@1.4.2 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>	2026-06-12 14:33:35 -07:00

When `addHandoffBackMessages` is not provided, it now defaults to the same value as `addHandoffMessages`, matching the Python package behavior. `createHandoffTool` now also accepts `description` as the preferred option name while continuing to support the existing `agentDescription` option as deprecated for backwards compatibility. ### Patch Changes - [#2407](https://github.com/langchain-ai/langgraphjs/pull/2407) [`59d4765`](https://github.com/langchain-ai/langgraphjs/commit/59d4765870bc0cddf3ef594b128ab3280533cb6c) Thanks [@pragnyanramtha](https://github.com/pragnyanramtha)! - Normalize all whitespace in supervisor handoff tool names. ## @langchain/langgraph@1.4.1 ### Patch Changes - [#2520](https://github.com/langchain-ai/langgraphjs/pull/2520) [`2da5c33`](https://github.com/langchain-ai/langgraphjs/commit/2da5c3374f7b91ba0afa607c507e2ff1591baca7) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(state): validate Zod state updates from nodes Validate node return values and Command updates against Zod state schema constraints before applying them to graph state.

When using `ToolNode` as a node in a LangGraph graph, this gives tools access to the current graph state for workflows that need tool-call support in LangGraph proper. Tools can type the second parameter as `ToolRuntime<StateType>` from `@langchain/core/tools` and read `runtime.state` directly. This works in every runtime, including web browsers, and removes the need for `getCurrentTaskInput()` (which relies on `node:async_hooks`/`AsyncLocalStorage`). `getCurrentTaskInput(config)` continues to work for backwards compatibility. - Updated dependencies \[[`3855985`](https://github.com/langchain-ai/langgraphjs/commit/3855985dd049739f145295d236ce6aa02ae2fb0e), [`7c3e9e9`](https://github.com/langchain-ai/langgraphjs/commit/7c3e9e93f3c7ec1dc654dac8ee8c03562ee8337b), [`17c44a3`](https://github.com/langchain-ai/langgraphjs/commit/17c44a38b7478e2bc4fe908a54c78ef33fb68ba3)]: - @langchain/langgraph-sdk@1.9.21 ## @langchain/langgraph-sdk@1.9.21 ### Patch Changes - [#2522](https://github.com/langchain-ai/langgraphjs/pull/2522) [`3855985`](https://github.com/langchain-ai/langgraphjs/commit/3855985dd049739f145295d236ce6aa02ae2fb0e) Thanks [@christian-bromann](https://github.com/christian-bromann)! - feat(stream): add per-event side-effect selector Add `useChannelEffect` (React/Svelte/Vue) / `injectChannelEffect` (Angular), a side-effect counterpart to `useChannel` that invokes an `onEvent` callback once per raw protocol event without re-rendering.

Christian Bromann	3855985dd0	fix(sdk): add per-event channel effect selector (#2522 ) ## Summary - Add a side-effect counterpart to `useChannel`: `useChannelEffect` (React, Svelte, Vue) and `injectChannelEffect` (Angular). It invokes an `onEvent` callback once per raw protocol event and returns nothing, so it never re-renders — the idiomatic v1 replacement for the removed `onLangChainEvent` / `onCustomEvent` callbacks used for analytics/logging. - Back all four bindings with a new framework-agnostic `acquireChannelEffect(registry, channels, namespace, options)` helper in `@langchain/langgraph-sdk/stream`. It acquires the same ref-counted `channelProjection` as `useChannel` (so an effect consumer and a matching `useChannel` share one server subscription and survive thread swaps), diffs the shared store by event identity, skips events buffered before it attaches (no double-counting history on a late mount), and resets correctly across thread rebinds. - API matches the agreed shape with `target`, `enabled`, `replay` (defaults to `false`/live-only — opposite of `useChannel`), `bufferSize`, `onEvent`, and `onError`. Callbacks are read from a ref/lazy wrapper so fresh inline closures never re-subscribe. - Update selector docs and `v1-migration.md` in all four SDKs, noting the callback now receives v1 protocol events (`lifecycle.`, `tools.`, `messages.*`, `custom`) rather than legacy LangChain event names. --------- Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>	2026-06-10 15:19:27 -07:00

The timer resets per retry attempt, and `NodeTimeoutError` is retryable under the default retry policy.

A new `RunControl` (exported from `@langchain/langgraph`) exposes `requestDrain(reason)` plus read-only `drainRequested` / `drainReason`. Pass it through the new `control` option on `invoke` / `stream` / `streamEvents` (and the functional API). It is surfaced on `runtime.control`, so nodes can read it or call `requestDrain()` themselves, and it is propagated into subgraphs. When a drain is requested, the Pregel loop checks the flag at the top of each superstep (after the previous step's writes are applied and checkpointed): if more tasks remain it saves the checkpoint and throws the new `GraphDrained` error (also under `durability: "exit"`), so the run can be resumed later from the same config. If the graph naturally finishes on that tick it returns normally and the caller can inspect `control.drainRequested`. A drain requested inside a subgraph bubbles up and stops the parent at its next boundary. Draining never cancels work that is already running — pair it with an `AbortSignal` if you need a hard upper bound. - [#2452](https://github.com/langchain-ai/langgraphjs/pull/2452) [`a8e7659`](https://github.com/langchain-ai/langgraphjs/commit/a8e7659a9d22fd84425aaf26bda88667c76b185a) Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add `DeltaChannel` and the writes-history saver API (beta). `DeltaChannel` is a reducer channel that stores only a sentinel in checkpoint blobs instead of the full accumulated value, reconstructing state on read by replaying ancestor writes through a batch reducer.

The handler runs ONLY after the failing node's `retryPolicy` is exhausted, so retry and handling stay decoupled. It receives a typed `NodeError { node, error }` and the typed node input state, can return a state update, and can route to a recovery branch via `new Command({ goto })` (saga / compensation flows). Failure provenance is checkpointed (via a reserved `ERROR_SOURCE_NODE` write) so handlers observe the same context after a checkpoint resume. Uncaught node errors without a handler still abort the run as before, and `GraphBubbleUp` errors (such as `interrupt()`) are never swallowed by a handler. `StateGraph.setNodeDefaults({ errorHandler })` now also accepts a graph-wide default handler. It is materialized at `compile()` as a single shared handler and invoked for every regular node that does not set its own `errorHandler`. A per-node handler always takes precedence, the default never catches a failure raised by an error-handler node itself (handler failures fail the run), and the default is not inherited by subgraphs. Ports the Python feature from langchain-ai/langgraph#7233. - [#2450](https://github.com/langchain-ai/langgraphjs/pull/2450) [`2f6d873`](https://github.com/langchain-ai/langgraphjs/commit/2f6d87368e590ae2fc2a7990fd13cb0a5fe3c198) Thanks [@christian-bromann](https://github.com/christian-bromann)! - Add node-level timeouts.

Previously a mixed `putWrites([[...regular...], [INTERRUPT, …]], taskId)` placed the INTERRUPT at a positive idx that could collide with a regular write at the same `(task_id, idx)`, and the unconditional `$set` upsert silently overwrote whichever row landed there first. The conflict-resolution clause now matches the Postgres / SQLite (TS and Python) checkpointers: `$set` only when every channel is a special one, `$setOnInsert` otherwise. ## @langchain/langgraph-checkpoint-postgres@1.0.3 ### Patch Changes - [#2512](https://github.com/langchain-ai/langgraphjs/pull/2512) [`375c73f`](https://github.com/langchain-ai/langgraphjs/commit/375c73fcd1ef06145301df80466fda35c0a99385) Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: reject SQL `LIKE` wildcards (`%`, `_`) and the backslash escape character in `PostgresStore` namespace labels. `BaseStore.search()` matches namespaces via `namespace_path LIKE ${prefix}%`, and these characters in caller-supplied namespace labels are interpreted as wildcards by Postgres even through a bound parameter — letting a namespace prefix of `["%"]` match every namespace in the store across tenants. `validateNamespace` now throws for these characters at all `search` / `get` / `put` entrypoints, keeping store-wide consistency. CWE-1336. ## @langchain/langgraph-checkpoint-redis@1.0.8 ### Patch Changes - [#2518](https://github.com/langchain-ai/langgraphjs/pull/2518) [`9182ea3`](https://github.com/langchain-ai/langgraphjs/commit/9182ea35ecc1f932eb864fa7dc4fb32a00c5f7d6) Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: `RedisSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`) to fixed negative indices in their Redis key (`checkpoint_write:…:<idx>`) instead of the call-local ordinal. Previously a mixed `putWrites([[…regular…], [INTERRUPT, …]], taskId)` placed the INTERRUPT key at the positive idx of its position in the batch, where a peer task's regular write at the same idx would overwrite it via the unconditional `JSON.SET`. The conflict-resolution clause now matches Postgres / SQLite / MongoDB: unguarded `JSON.SET` when every write is a special channel, `JSON.SET … NX` (insert-or-ignore) otherwise. ## @langchain/langgraph-checkpoint-sqlite@1.0.3 ### Patch Changes - [#2516](https://github.com/langchain-ai/langgraphjs/pull/2516) [`f6a6d26`](https://github.com/langchain-ai/langgraphjs/commit/f6a6d26b7e69003c4fa052f3cd3319f3e72f0f8f) Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: `SqliteSaver.putWrites` now honors `WRITES_IDX_MAP`, pinning special channels (`__error__`, `__scheduled__`, `__interrupt__`, `__resume__`) to fixed negative indices instead of the call-local ordinal. Previously a follow-up `putWrites([[INTERRUPT, …]], taskId)` for the same checkpoint silently `REPLACE`d the regular write previously stored at `idx=0` for that task, losing data. The conflict-resolution clause also now matches the Python checkpointer contract: `OR REPLACE` only when every channel is a special one (so e.g. INTERRUPT→RESUME state transitions overwrite), `OR IGNORE` otherwise. ## @langchain/angular@1.0.21 ### Patch Changes - [#2515](https://github.com/langchain-ai/langgraphjs/pull/2515) [`49b8c1a`](https://github.com/langchain-ai/langgraphjs/commit/49b8c1a04cf03a77069a955816b0f5af2f68ab41) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix: make AnyStream a true supertype so selector hooks need no cast A concrete `useStream<typeof agent>()` handle was not assignable to `AnyStream` because generic-computed covariant members (`toolCalls`, `values`) don't widen under `any` — `InferToolCalls<any>[]` resolves to `AssembledToolCall<…, never>[]`, narrower than a concrete handle.

Christian Bromann	49b8c1a04c	fix: make AnyStream a true supertype so selector hooks need no cast (#2515 ) ## Summary - `AnyStream` (`UseStreamReturn<any, any, any>`) was not actually a supertype of concrete stream handles: members computed from the generics in covariant positions don't collapse under `any`. `toolCalls` resolves via `InferToolCalls<any>` to `AssembledToolCall<string, …, never>[]`, whose `never` output slot is narrower than a concrete handle's `unknown`, so `UseStreamReturn<typeof agent>` failed to assign and every `useMessages`/`useToolCalls`/`useValues` (`inject*` on Angular) call required an `as AnyStream` cast. - Redefined `AnyStream` in all four framework packages to `Omit` the generic-computed members and re-add them at their widest forms, preserving each framework's reactivity wrapper: plain arrays for React/Svelte, `Readonly<ShallowRef<…>>` for Vue, `Signal<…>` for Angular. React also drops `~stateType` (the only package that has that member). - Retyped each package's internal `getRegistry` to accept `AnyStream`, removed React's duplicate local `AnyStream` in `selectors.ts` in favor of the public type, and corrected the misleading doc comments. - Downstream (`langchainplus` agent-chat-v2) can drop its `stream as AnyStream` casts once these ship.	2026-06-09 20:27:08 -07:00

Christian Bromann	41cd05a411	fix(sdk): hydrate custom transport without extra client config (#2508 ) ## Summary - `StreamController.hydrate()` calls `transport.getState()` when the adapter implements it, then falls back to `client.threads.getState()`. - `HttpAgentServerAdapter` / `ProtocolSseTransportAdapter` add `getState()` via `GET /threads/:threadId/state` (optional `paths.state` override). - `resolveClientApiUrl()` lets `useStream` build the hydration `Client` from the transport’s `apiUrl` when none is passed explicitly. - React, Vue, and Angular `useStream` hooks use the resolver so custom-backend apps only need `transport={adapter}`.	2026-06-08 18:06:16 -07:00

This removes duplicated logic across `session/index.mts`, `session/namespace.mts`, `session/internal-types.mts`, and `service.mts`. This also aligns SSE event-sink filtering (`matchesSinkFilter`) with the WebSocket subscription matcher: both now normalize dynamic namespace suffixes (e.g. a `["fetcher"]` namespace filter matches an event emitted under `["fetcher:<uuid>"]`). Previously the SSE path used a stricter exact-segment match. Because the session now imports `@langchain/langgraph/stream`, the `@langchain/langgraph` peer dependency floor is raised to `^1.3.6` (the first release that ships the `/stream` entrypoint). ### Patch Changes - Updated dependencies \[]: - @langchain/langgraph-ui@1.3.0 ## @langchain/langgraph-checkpoint-sqlite@1.0.2 ### Patch Changes - [#2504](https://github.com/langchain-ai/langgraphjs/pull/2504) [`e8a0940`](https://github.com/langchain-ai/langgraphjs/commit/e8a09409ac4a997012e78081160c91188ebe39fc) Thanks [@jackjin1997](https://github.com/jackjin1997)! - fix: `SqliteSaver.list({}, { filter })` now honors arbitrary metadata keys (e.g. `tenant_id`, `env`), matching the behavior of the MongoDB, Postgres, and Redis checkpointers.

Alongside the existing `StreamChannel` and `convertToProtocolEvent`, it exposes subscription primitives, typed against a minimal `MatchableEvent` shape so they work on both the core `ProtocolEvent` and the wire-level `Event` from `@langchain/protocol`: - `inferChannel(event)` — map an event to its subscription `Channel` (named `custom:<name>` channels included). - `matchesSubscription(event, definition)` — decide whether a buffered event should be delivered for a `SubscribeParams` filter, honoring channel, namespace prefix/depth, and an optional `since` replay cursor. - `isPrefixMatch(namespace, prefix)` / `normalizeNamespaceSegment(segment)` — namespace prefix matching with dynamic-suffix normalization (e.g. `fetcher:<uuid>` matches the `fetcher` prefix). - `SUPPORTED_CHANNELS` / `isSupportedChannel(value)` — the recognized channel set and a guard for validating subscription requests. - Updated dependencies \[[`cad31b4`](https://github.com/langchain-ai/langgraphjs/commit/cad31b42f001a87fcdf57c4c084c655c8762b6a5)]: - @langchain/langgraph-sdk@1.9.19 ## @langchain/langgraph-sdk@1.9.19 ### Patch Changes - [#2505](https://github.com/langchain-ai/langgraphjs/pull/2505) [`cad31b4`](https://github.com/langchain-ai/langgraphjs/commit/cad31b42f001a87fcdf57c4c084c655c8762b6a5) Thanks [@christian-bromann](https://github.com/christian-bromann)! - Deduplicate the client stream transports: the protocol transport now shares the SSE decoder and `IterableReadableStream` helpers with the legacy transport instead of carrying its own copies. Removes the redundant `transport/decoder.ts` and `transport/stream.ts` shims (and a dead `StreamPart` re-export), importing the shared utilities from `utils/sse.ts` directly.

Christian Bromann	f67772ff3f	fix(sdk): resume useChannel subscriptions across serial runs (#2500 ) ## Summary - Fix `channelProjection` to pass `resumeOnPause: true`, matching `extensionProjection`, so `useChannel` continues receiving events after each run's terminal lifecycle event instead of going silent after the first prompt on a thread. - Add a unit test that simulates a paused subscription resuming with a second event batch, and a React browser integration test asserting `useChannel` event count grows across two serial submits (3 → 6). - Update selector JSDoc and `selectors.md` / `selector-composables.md` across React, Vue, Svelte, and Angular to document the complementary roles: `useChannel` = full bounded event history across runs; `useExtension` = latest payload only.	2026-06-06 15:29:59 -07:00

dependabot[bot]	f552c05813	chore(deps): bump hono from 4.12.18 to 4.12.21 (#2492 ) Bumps [hono](https://github.com/honojs/hono) from 4.12.18 to 4.12.21. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/honojs/hono/releases">hono's releases</a>.</em></p> <blockquote> <h2>v4.12.21</h2> <h2>Security fixes</h2> <p>This release includes fixes for the following security issues:</p> <h3>app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths</h3> <p>Affects: <code>app.mount()</code>. Fixes prefix stripping using the raw URL pathname instead of the decoded path, where percent-encoded characters in the mount prefix or path could cause the prefix to be removed at the wrong position, resulting in the sub-application receiving an incorrect path. GHSA-2gcr-mfcq-wcc3</p> <h3>IP Restriction bypasses static deny rules for non-canonical IPv6</h3> <p>Affects: <code>hono/ip-restriction</code>. Fixes IP address comparison using string equality, where non-canonical IPv6 representations of a denied address — such as compressed forms or hex-notation IPv4-mapped addresses — could bypass static deny rules. GHSA-xrhx-7g5j-rcj5</p> <h3>Cookie helper does not sanitize sameSite and priority, allowing Set-Cookie injection</h3> <p>Affects: <code>hono/cookie</code>. Fixes missing validation of <code>sameSite</code> and <code>priority</code> options against injection characters (<code>;</code>, <code>\r</code>, <code>\n</code>), where user-controlled input passed to either option could inject additional attributes into the Set-Cookie response header. GHSA-3hrh-pfw6-9m5x</p> <h3>JWT middleware accepts any Authorization scheme, not only Bearer</h3> <p>Affects: <code>hono/jwt</code>, <code>hono/jwk</code>. Fixes missing scheme validation in the Authorization header, where any two-part header value was accepted regardless of the scheme name, allowing non-Bearer schemes to pass JWT authentication. GHSA-f577-qrjj-4474</p> <hr /> <p>Users who use <code>app.mount()</code>, <code>hono/ip-restriction</code>, <code>hono/cookie</code>, or <code>hono/jwt</code>/<code>hono/jwk</code> are encouraged to

Christian Bromann	0a0e04e9ff	fix(sdk): revive automatic optimistic submit echo (#2494 ) ## Summary - revive automatic optimistic updates to `@langchain/langgraph-sdk`: `submit()` input is echoed into `values` / `messages` immediately, messages without ids get client-minted ids for server reconciliation, and non-message keys are shallow-merged with rollback when no `values` snapshot arrives. - Track per-message lifecycle via `useMessageMetadata(...).optimisticStatus` (`pending` → `sent` / `failed`); failed optimistic messages are kept for retry UX and dropped on `hydrate()`. - Plumb `optimistic?: boolean` through React, Vue, Svelte, and Angular `useStream` hooks (defaults to enabled) and document the v1 migration path replacing legacy `optimisticValues`. - Add browser e2e tests across all four framework SDKs covering message happy path, id reconciliation, failure handling, opt-out, and non-message state convergence/rollback.	2026-06-04 20:58:57 -07:00

The content pump and lifecycle watcher are independent streams, so this reordering could strand nodes as perpetually running in `useStream` subgraph UIs. ## @langchain/angular@1.0.14 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 ## @langchain/react@1.0.14 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 ## @langchain/svelte@1.0.14 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 ## @langchain/vue@1.0.14 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 ## @example/ai-elements@0.1.29 ### Patch Changes - Updated dependencies \[]: - @langchain/react@1.0.14 ## @examples/assistant-ui-claude@0.1.29 ### Patch Changes - Updated dependencies \[]: - @langchain/react@1.0.14 ## @examples/ui-angular@0.0.39 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 - @langchain/angular@1.0.14 ## @examples/ui-multimodal@0.0.15 ### Patch Changes - Updated dependencies \[]: - @langchain/react@1.0.14 ## @examples/ui-react@0.0.15 ### Patch Changes - Updated dependencies \[[`ba583b6`](https://github.com/langchain-ai/langgraphjs/commit/ba583b601d284c689bbfc15397686f1aa7481fba)]: - @langchain/langgraph-sdk@1.9.14 - @langchain/react@1.0.14 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>	2026-06-03 15:19:03 -07:00

Christian Bromann	0491534712	fix(sdk): route headless tool resumes through respond on v1 stream (#2467 ) ## Summary - Fix headless-tool resume on the v1 stream protocol by routing resume payloads through `applyHeadlessToolResumeCommand` (`respond` / `respondAll`) instead of `submit(null, { command })`. - Export `applyHeadlessToolResumeCommand` and `HeadlessToolResumeController` from `@langchain/langgraph-sdk` and re-export from `@langchain/react`. - Strengthen headless-tool browser tests across React, Vue, Angular, and Svelte to assert tool result values, final agent message, idle loading state, and no lingering interrupts.	2026-06-02 10:53:27 -07:00

A caller able to shape any of those fields (every quickstart, tutorial, and test fixture uses `MemorySaver` by default) could pass `"__proto__"`, `"constructor"`, or `"prototype"` and have the subsequent assignment mutate `Object.prototype`. From that point every plain object in the process inherits the injected property, breaking `for...in` loops, truthy short-circuits, and downstream serializers across unrelated code paths. CWE-1321. Adds an `assertSafeStorageKey` chokepoint applied at every public entry that touches `storage` or `writes` (`put`, `putWrites`, `deleteThread`, `getTuple`, `list`). The guard rejects non-string values, the empty string (unless explicitly opted-in for `checkpoint_ns`), and the three prototype-pollution keys. Behaviour for valid string identifiers is unchanged. ## @langchain/langgraph-checkpoint-redis@1.0.6 ### Patch Changes - [#2350](https://github.com/langchain-ai/langgraphjs/pull/2350) [`1e73c6b`](https://github.com/langchain-ai/langgraphjs/commit/1e73c6b4630bbc4aa976eea4bfc33c4f753b7ee9) Thanks [@Nagendhra-web](https://github.com/Nagendhra-web)! - fix(checkpoint-redis): block Redis KEYS / SCAN pattern injection via top-level identifiers `RedisSaver` and `ShallowRedisSaver` previously embedded `thread_id`, `checkpoint_ns`, `checkpoint_id`, and `task_id` directly into Redis keys and `client.keys(pattern)` calls with no validation. A caller able to shape any of those fields (multi-tenant SDK deployments where the `RunnableConfig` originates from request input, or webhook payloads that flow into a persisted thread) could promote a string identifier into a glob pattern (``, `?`, `[...]`) or escape character (`\`). The most severe sink is `deleteThread`: a `threadId` of `` issues `client.keys("checkpoint::")` followed by `client.del(...)`, deleting every checkpoint in the database across every tenant. `getTuple`, `list`, and `loadPendingWrites` are exposed to the same pattern via the fallback paths that bypass the existing `escapeRediSearchTagValue` defense. Adds a single `assertSafeKeyComponent` helper exported from `./utils.js` and applies it at every key-building site. The guard asserts the value is a non-empty string (the empty `checkpoint_ns` default is opt-in via `{ allowEmpty: true }`) and rejects the Redis pattern meta-characters `* ? [ ] \`. The `:` delimiter is intentionally permitted because LangGraph emits it as a legitimate part of `checkpoint_ns` for subgraphs / nested graphs, where it only ever appears as a literal in the key. Behavior for valid string identifiers is unchanged. ## @langchain/langgraph-api@1.2.3 ### Patch Changes - [#2447](https://github.com/langchain-ai/langgraphjs/pull/2447) [`80c2806`](https://github.com/langchain-ai/langgraphjs/commit/80c2806cb2da93745a640664bd0cf603c2361da9) Thanks [@christian-bromann](https://github.com/christian-bromann)! - protocol-v2: fold forkFrom client-side and honor per-run multitaskStrategy The SDK now folds the ergonomic `forkFrom` option into `config.configurable.checkpoint_id` before sending `run.start`, so the agent server only ever accepts the single, legacy-compliant fork field (`forkFrom` no longer hits the wire).

Christian Bromann	2c14b12a80	fix(sdk): add back respondAll and respond config/metadata (#2448 ) ## 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.	2026-05-28 16:53:09 -07:00

Christian Bromann	3529e3831a	fix(sdk): align AssembledToolCall typing with pre-v1 expectations (#2421 ) ## 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.	2026-05-22 06:38:06 -07:00

Hunter Lovell	01dd0462ed	fix(sdk): retry connection failures before throwing ConnectionError (#2388 ) ## Summary This change updates SDK retry behavior so connection-related failures are retried instead of immediately aborting inside `onFailedAttempt`. When retries are exhausted, the final surfaced error is still coalesced to a `ConnectionError` with the existing LangGraph-specific guidance. A focused unit test was added to lock in this behavior. ## Changes ### @langchain/langgraph-sdk - Updated `AsyncCaller` connection-error handling to only throw `ConnectionError` on the final failed attempt (`retriesLeft === 0`), while allowing retries on earlier attempts. - Added a regression test covering retry count plus final `ConnectionError` coalescing for connection-refused/fetch-failed style errors. - Added a patch changeset for `@langchain/langgraph-sdk` documenting the retry/coalescing fix.	2026-05-18 10:27:49 -07:00

dependabot[bot]	aa6deb60c7	chore(deps): bump hono from 4.12.14 to 4.12.18 (#2374 ) Bumps [hono](https://github.com/honojs/hono) from 4.12.14 to 4.12.18. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/honojs/hono/releases">hono's releases</a>.</em></p> <blockquote> <h2>v4.12.18</h2> <h2>Security fixes</h2> <p>This release includes fixes for the following security issues:</p> <h3>Cache Middleware ignores Vary: Authorization / Vary: Cookie leading to cross-user cache leakage</h3> <p>Affects: Cache Middleware. Fixes missing cache-skip handling for <code>Vary: Authorization</code> and <code>Vary: Cookie</code>, where a response cached for one authenticated user could be served to other users. GHSA-p77w-8qqv-26rm</p> <h3>CSS Declaration Injection via Style Object Values in JSX SSR</h3> <p>Affects: hono/jsx. Fixes a missing CSS-context escape for <code>style</code> object values and property names, where untrusted input could inject additional CSS declarations. The impact is limited to CSS and does not allow JavaScript execution. GHSA-qp7p-654g-cw7p</p> <h3>Improper validation of NumericDate claims (exp, nbf, iat) in JWT verify()</h3> <p>Affects: <code>hono/utils/jwt</code>. Fixes improper validation of <code>exp</code>, <code>nbf</code>, and <code>iat</code> claims, where falsy, non-finite, or non-numeric values could silently bypass time-based checks instead of being rejected per RFC 7519. GHSA-hm8q-7f3q-5f36</p> <hr /> <p>Users who use the JWT helper, hono/jsx, or the Cache middleware are strongly encouraged to upgrade to this version.</p> <h2>v4.12.17</h2> <h2>What's Changed</h2> <ul> <li>fix(jsx): normalize SVG attributes on the <!-- raw HTML omitted --> root element by <a href="https://github.com/kfly8"><code>@kfly8</code></a> in <a href="https://redirect.github.com/honojs/hono/pull/4893">honojs/hono#4893</a></li> <li>fix(ssg): add <code>atom+xml</code> and <code>rss+xml</code> to <code>defaultExtensionMap</code> by <a href="https://github.com/yuintei"><code>@yuintei</code></a> in <a href="https://redirect.github.com/honojs/hono/pull/4899">honojs/hono#4899</a></li> <li>fix(cors): make origin optional in CORSOptions by <a href="https://github.com/truffle-dev"><code>@truffle-dev</code></a> in <a href="https://redirect.github.com/honojs/hono/pull/4905">honojs/hono#4905</a></li> <li>fix(types): propagate middleware response types to app.on overloads by <a href="https://github.com/T4ko0522"><code>@T4ko0522</code></a> in <a href="https://redirect.github.com/honojs/hono/pull/4906">honojs/hono#4906</a></li> </ul> <h2>New Contributors</h2> <ul> <li><a href="https://github.com/kfly8"><code>@kfly8</code></a> made their first contribution in <a href="https://redirect.github.com/honojs/hono/pull/4893">honojs/hono#4893</a></li> <li><a href="https://github.com/truffle-dev"><code>@truffle-dev</code></a> made their first contribution in <a href="https://redirect.github.com/honojs/hono/pull/4905">honojs/hono#4905</a></li> </ul> <p><strong>Full Changelog</strong>: <a href="https://github.com/honojs/hono/compare/v4.12.16...v4.12.17">https://github.com/honojs/hono/compare/v4.12.16...v4.12.17</a></p> <h2>v4.12.16</h2> <h2>Security fixes</h2> <p>This release includes fixes for the following security issues:</p> <h3>Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection</h3> <p>Affects: hono/jsx. Fixes missing validation of JSX tag names when using <code>jsx()</code> or <code>createElement()</code>, which could allow HTML injection if untrusted input is used as the tag name. GHSA-69xw-7hcm-h432</p> <h3>bodyLimit() can be bypassed for chunked / unknown-length requests</h3> <p>Affects: Body Limit Middleware. Fixes late enforcement for request bodies without a reliable Content-Length (e.g. chunked requests), where oversized requests could reach handlers and return successful responses before being rejected.
