Anthropic SDK v0.110.0
June 19, 2026
v0.110.0, released on 2026-06-18, adds support for the new `code_execution_20260120` tool in the API and includes bug fixes for header merging, Bedrock stream event type preservation, and `x-stainless-helper` key handling. The notable detail is the new tool integration plus a cleanup of helper/header behavior, which should improve compatibility and reduce subtle request/streaming bugs.
