feature patch

Anthropic has released Python SDK v1.2.0, which stabilizes beta API namespaces for files and skills by aligning them with generally available shapes and dropping dated beta header pins. This update improves consistency and future compatibility for developers interacting with these features. Key bug fixes include enabling binary file uploads via AWS Bedrock and ensuring forward compatibility with new event types. The release also addresses several tool-related issues, such as preserving exact file bytes in agent toolsets.

  • →beta files/skills namespaces use GA shapes; drop dated beta header pins
  • →aws,bedrock: sign raw request bytes so binary file uploads work
  • →resolve assignment aliases in detect-breaking-changes
  • →make event accumulator forward-compatible with new event types
  • →let read return a view_range of a file over the size cap
