Both SDKs' 1.x/3.x majors run on httpx2 (the maintained fork of httpx by its original author, published by Pydantic at github.com/pydantic/httpx2, version line 2.x) instead of httpx, which is what makes these two bumps one change. httpx2 is now a declared dependency because two modules import it directly. Everything else in the 0.x -> 1.x / 2.x -> 3.x change lists is absent here: no Text Completions, no `with_raw_response`, no raw `output_format` dicts, no Bedrock client, and `requires-python` is already 3.12. Three code changes, all forced by the bump: The BYOM DNS-pinning client in `docsgpt/security/safe_url.py` is handed to `OpenAI(http_client=...)`, and the SDK rejects an old-httpx client at construction — which would have taken the SSRF guard offline. It is built on httpx2 now, and its `sni_hostname` extension carries a `str` rather than ascii bytes: httpcore passes the value straight to `ssl.SSLContext.wrap_socket`, and the truststore backend httpx2 uses for the default system trust store encodes it instead of accepting bytes. Bytes therefore failed every real handshake while passing the existing tests, which stub the transport out; the test now pins the type and says why. The stream-retry error tuple in `docsgpt/llm/base.py` named `httpx` exceptions only. The two libraries' exception classes are unrelated types, so after the bump the retry silently stopped firing for openai and anthropic while still working for google-genai and elevenlabs. It now covers both stacks, with a parametrized test over each. anthropic 1.x dropped temperature/top_p/top_k from `messages.create`'s signature (passing one raises TypeError) without dropping them from the API, so the provider forwards them through `extra_body`. The wire request is unchanged and a model that rejects them 400s exactly as before.
