- Improved abort signal handling for chat models: - Added `ModelAbortError` class in `@langchain/core/errors` that contains partial output when a model invocation is aborted mid-stream - `invoke()` now throws `ModelAbortError` with accumulated `partialOutput` when aborted during streaming (when using streaming callback handlers) - `stream()` throws a regular `AbortError` when aborted (since chunks are already yielded to the caller) - All provider implementations now properly check and propagate abort signals in both `_generate()` and `_streamResponseChunks()` methods - Added standard tests for abort signal behavior - [#9900](https://github.com/langchain-ai/langchainjs/pull/9900) [`a9b5059`](https://github.com/langchain-ai/langchainjs/commit/a9b50597186002221aaa4585246e569fa44c27c8) Thanks [@hntrl](https://github.com/hntrl)! - fix(providers): add proper abort signal handling for invoke and stream operations - Added early abort check (`signal.throwIfAborted()`) at the start of `_generate` methods to immediately throw when signal is already aborted - Added abort signal checks inside streaming loops in `_streamResponseChunks` to return early when signal is aborted - Propagated abort signals to underlying SDK calls where applicable (Google GenAI, Google Common/VertexAI, Cohere) - Added standard tests for abort signal behavior in `@langchain/standard-tests` This enables proper cancellation behavior for both invoke and streaming operations, and allows fallback chains to correctly proceed to the next runnable when the previous one is aborted. - [#9875](https://github.com/langchain-ai/langchainjs/pull/9875) [`a000b0f`](https://github.com/langchain-ai/langchainjs/commit/a000b0f642f24dd6a2159a4fa2c6bda5838a68e1) Thanks [@joeljohn159](https://github.com/joeljohn159)!

- fix: handle "tool_call" content blocks in ChatGoogleGenerativeAI with outputVersion: "v1" Previously, using `outputVersion: "v1"` with `ChatGoogleGenerativeAI` would throw an "Unknown content type tool_call" error when processing tool calls generated by LangChain's `AIMessage`. This fix adds a handler for the `tool_call` block type in the conversion utility, ensuring compatibility with standard LangChain tool call blocks. ## 2.1.11 ### Patch Changes - [#9827](https://github.com/langchain-ai/langchainjs/pull/9827) [`e16c218`](https://github.com/langchain-ai/langchainjs/commit/e16c218b81980a1c576af5192342019975bb95b9) Thanks [@sanjaiyan-dev](https://github.com/sanjaiyan-dev)!
