v2.5.0

Compatibility Notes

• [langchain] The @langchain/core package is now a peer dependency.
  You now have to install the @langchain/core package as a direct dependency of your project. (5b88f6f)

New Features

• [langchain] Support disabling streaming completely via the langchain option disableStreaming. (b91e0a7)
• [langchain] Support auto-streaming via the langchain option streaming. When enabled (e.g., transparently by LangGraph), responses are automatically streamed in invoke() calls. (b91e0a7)
• [orchestration] Add support for orchestration configuration references in the orchestration client. (2f19a40)

Fixed Issues

• [langchain] Pin @langchain/core to v1.1.8 to avoid a regression. (9ff7cec)

Improvements

• [langchain] Move the @langchain/core package from dependencies to peer dependencies.
  This reduces the chance of version incompatibilities between langchain-related packages. (5b88f6f)
