# @langchain/ollama ## 1.2.6 ### Patch Changes - [#10212](https://github.com/langchain-ai/langchainjs/pull/10212) [`9920cfe`](https://github.com/langchain-ai/langchainjs/commit/9920cfed2b9588b8ba401088b49c0bf9820634ca) Thanks [@colifran](https://github.com/colifran)! - feat(ollama): implement standard schema support for structured output ## 1.2.5 ### Patch Changes - [#10106](https://github.com/langchain-ai/langchainjs/pull/10106) [`9f30267`](https://github.com/langchain-ai/langchainjs/commit/9f30267e95a2a42fac71f1d3674b84c5a190dbbc) Thanks [@hntrl](https://github.com/hntrl)! - Add package version metadata to runnable traces. Each package now stamps its version in `this.metadata.versions` at construction time, making version info available in LangSmith trace metadata. ## 1.2.4 ### Patch Changes - [#10080](https://github.com/langchain-ai/langchainjs/pull/10080) [`b583729`](https://github.com/langchain-ai/langchainjs/commit/b583729e99cf0c035630f6b311c4d069a1980cca) Thanks [@hntrl](https://github.com/hntrl)! - Add string-model constructor overloads for chat models (with supporting tests where applicable). ## 1.2.3 ### Patch Changes - [#10065](https://github.com/langchain-ai/langchainjs/pull/10065) [`e2b3d90`](https://github.com/langchain-ai/langchainjs/commit/e2b3d90a7b27dbb6a303e52bab08a1c881c2c850) Thanks [@MatanTsach](https://github.com/MatanTsach)! - fix(ollama): preserve tool_calls when AIMessage content is a string ## 1.2.2 ### Patch Changes - [#9900](https://github.com/langchain-ai/langchainjs/pull/9900) [`a9b5059`](https://github.com/langchain-ai/langchainjs/commit/a9b50597186002221aaa4585246e569fa44c27c8) Thanks [@hntrl](https://github.com/hntrl)! - 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. ## 1.2.1 ### Patch Changes - [#9793](https://github.com/langchain-ai/langchainjs/pull/9793) [`82d7df7`](https://github.com/langchain-ai/langchainjs/commit/82d7df7435165d1d53103f3d009011e9268be14e) Thanks [@bao-tran-iohub](https://github.com/bao-tran-iohub)!
