+We've released
+v1.0 of the
+Python SDK
+. The SDK's HTTP layer moves from
+httpx
+to
+httpx2
+, a maintained, API-compatible fork: build custom
+http_client

+Timeout
+, and transport objects from
+httpx2
+(the
+DefaultHttpxClient
+helpers are unchanged), and call
+httpx2.alias_httpx()
+at startup if you rely on tracing or mocking libraries that patch
+httpx
+. v1.0 requires Python 3.10 or later and removes long-deprecated surface, including the legacy Text Completions API, the
+temperature

+top_p
+, and
+top_k
+parameters on Messages methods, and the tool runner's client-side
+compaction_control
+. On the async client,

+AnthropicBedrock
+now raises an error when no AWS region is configured instead of defaulting to
+us-east-1
