Anthropic Python SDK 1.4.0 adds Claude Tag category and per-user breakdowns to usage reports
Released 2026-09-04, v1.4.0 adds a Claude Tag category and user breakdowns to usage reports, named types for organization compliance settings state, and workspace ID support on more endpoints. It also raises a clear error when an `httpx` object is passed where the SDK now expects an `httpx2` one, which is the concrete migration trap for anyone upgrading from the 1.3 line. The matching TypeScript SDK went to sdk-v0.124.0 the same minute, alongside vertex 0.19.7, bedrock 0.33.4, foundry 0.4.5 and aws 0.7.0.
