Anthropic Python SDK v1.6.0
Anthropic Python SDK v1.6.0 introduces Managed Agents auto-mode tool permissions, compaction beta parameters, async credential token providers, and critical client retry bug fixes.
Why this signal matters
Anthropic Python SDK v1.6.0 introduces several new API features, client improvements, and bug fixes. Key additions include auto mode tool permissions for Managed Agents, beta support for compaction parameters and signed compaction blocks, enum types for workspace data-residency geo fields, URL sources in the web fetch tool, and workspace ID parameters for user profile methods. Client changes add support for async credential token providers, fix non-blocking coroutine retries for async client connection errors, honor Retry-After headers exceeding 60 seconds (falling back to default backoff when out of range), and ignore invalid Retry-After values while validating maxRetries. Dependency updates require anyio = 4.1.
Actionable summary
Anthropic Python SDK release v1.6.0 adds Managed Agents auto mode tool permissions, beta compaction and thinking mismatch parameters, async credential token providers, and updates dependencies requiring anyio = 4.1 alongside client retry handling fixes.

What builders should check
- Ensure environment dependencies satisfy anyio 4.1 or later.
- Review retry configurations to account for validated maxRetries and updated Retry-After handling behavior.
- Optionally migrate to async credential token providers if managing asynchronous credentials.
