With tracing on, a nested `streamMode: "messages"` run delivered every token twice. - Updated dependencies [[`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f), [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924), [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5)]: - @langchain/langgraph-sdk@1.9.30 ## @langchain/langgraph-sdk@1.9.30 ### Patch Changes - [#2691](https://github.com/langchain-ai/langgraphjs/pull/2691) [`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(sdk): clear messages on hydrate(null) with a pending interrupt Teardown awaited the paused root pump, so threadId went null while the old conversation stayed on screen. Reset the snapshot first. - [#2703](https://github.com/langchain-ai/langgraphjs/pull/2703) [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(sdk): keep isLoading true across interrupt→running hydration Deferred terminal resets no longer clear isLoading when a newer running lifecycle has already arrived (HITL resume / SSE replay). - [#2692](https://github.com/langchain-ai/langgraphjs/pull/2692) [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(sdk): adopt server metadata on same-id optimistic message echo When a `values` snapshot echoes an optimistic human with the same content plus committed `additional_kwargs` (e.g. attachment paths), `stream.messages` now takes the server copy instead of keeping the plain optimistic message until hydration. Preferring is asymmetric: lagging or poorer values snapshots do not strip richer current metadata. In-flight AI token streaming is unchanged: streamed content still wins when it has moved past the snapshot. ## @langchain/angular@1.0.31 ### Patch Changes - Updated dependencies [[`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f), [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924), [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5)]: - @langchain/langgraph-sdk@1.9.30 ## @langchain/react@1.0.31 ### Patch Changes - Updated dependencies [[`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f), [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924), [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5)]: - @langchain/langgraph-sdk@1.9.30 ## @langchain/svelte@1.0.31 ### Patch Changes - Updated dependencies [[`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f), [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924), [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5)]: - @langchain/langgraph-sdk@1.9.30 ## @langchain/vue@1.0.31 ### Patch Changes - Updated dependencies [[`3ce9f8d`](https://github.com/langchain-ai/langgraphjs/commit/3ce9f8d11dd64b1d091a25162603c49e6f4a426f), [`51b4202`](https://github.com/langchain-ai/langgraphjs/commit/51b42020f7c730a15193aa907056881e3d961924), [`a86f813`](https://github.com/langchain-ai/langgraphjs/commit/a86f813954e010fbf30711c37baa5c53444613d5)]: - @langchain/langgraph-sdk@1.9.30 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>
