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/quickjs@0.6.0 ### Minor Changes - [#606](#606) [`3c8f8b2`](3c8f8b2) Thanks [@colifran](https://github.com/colifran)! - chore(quickjs): disallow task as a configurable ptc tool ## deepagents-acp@0.1.16 ### Patch Changes - Updated dependencies [[`d7ecab2`](d7ecab2), [`1a2b2df`](1a2b2df), [`42f34b6`](42f34b6), [`0ae10d7`](0ae10d7)]: - deepagents@1.10.6 ## deepagents@1.10.6 ### Patch Changes - [#608](#608) [`d7ecab2`](d7ecab2) Thanks [@aolsenjazz](https://github.com/aolsenjazz)! - fix(deepagents): forward subagent results as text Fixed a 400 `invalid_request_error` that occurred when a subagent used an Anthropic server-side tool (web search, web fetch, or code execution): the subagent's `server_tool_use`/`*_tool_result` blocks were forwarded to the parent agent as `tool_result` content, which the API rejects. Subagent results are now passed back to the parent as their text content (matching the Python implementation), which resolves the error and also handles a trailing empty `end_turn` message. - [#656](#656) [`1a2b2df`](1a2b2df) Thanks [@colifran](https://github.com/colifran)! - fix(deepagents): default unknown file extensions to text/plain - [#611](#611) [`42f34b6`](42f34b6) Thanks [@aolsenjazz](https://github.com/aolsenjazz)! - feat(deepagents): add bedrockPromptCachingMiddleware to default stack Add bedrockPromptCachingMiddleware to default middleware stack. This automatically opts-in to Bedrock prompt caching for Nova and Anthropic models - [#613](#613) [`0ae10d7`](0ae10d7) Thanks [@christian-bromann](https://github.com/christian-bromann)! - fix(deepagents): declare LangChain runtime packages as peer dependencies Move `@langchain/core`, `@langchain/langgraph`, `@langchain/langgraph-sdk`, and `langchain` from `dependencies` to `peerDependencies`, and also declare `@langchain/langgraph-checkpoint` as a peer (its `BaseCheckpointSaver`/`BaseStore` types are part of the public API), so they resolve to a single shared instance in the consumer's tree. Previously they were bundled as regular dependencies, which let a consumer end up with two copies of `@langchain/core` (e.g. `1.2.0` vs `1.2.1`). Because these packages ship classes with private/ protected fields, the duplicate copies are treated as nominally distinct types, producing errors like passing a `ChatOpenAI` model to `createDeepAgent` or a compiled graph to the local protocol helpers. As peers, the app controls the version and bumping `@langchain/core` no longer requires a `deepagents` release. ## @langchain/daytona@0.2.1 ### Patch Changes - [#614](#614) [`5b462f2`](5b462f2) Thanks [@christian-bromann](https://github.com/christian-bromann)! - Replace deprecated `@daytonaio/sdk` dependency with `@daytona/sdk`. ## @langchain/modal@0.1.5 ### Patch Changes - [#657](#657) [`5f93c11`](5f93c11) Thanks [@colifran](https://github.com/colifran)! - fix(modal): modal low level file handle api `sandbox.open` has been removed ## @deepagents/evals@0.0.15 ### Patch Changes - Updated dependencies [[`d7ecab2`](d7ecab2), [`1a2b2df`](1a2b2df), [`42f34b6`](42f34b6), [`0ae10d7`](0ae10d7)]: - deepagents@1.10.6 --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Colin Francis <colin.francis@langchain.dev>
