What probably matters to youSection of the release
What
A new reference document ships inside Claude Code, reached from the /claude-api upgrade flow, walking a project through the 0.x to 1.x migration step by step.
Details
Steps covered: bump the pin, raise the Python floor to 3.10, move httpx objects that cross the SDK boundary to the httpx2 fork or call httpx2.alias_httpx() at an entry point, await .with_raw_response body reads on async clients, port completions.create plus HUMAN_PROMPT/AI_PROMPT to Messages, drop temperature/top_p/top_k, rewrite raw output_format={...} as output_config={"format": {...}}, and supply an explicit Bedrock region.
The document is a plain text constant in the bundle with no gate around it.
Evidence
# Upgrading the anthropic Python SDK: 0.x → 1.x
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
