Anthropic's Python SDK v1.6.0 introduces new API features for Managed Agents, compaction, workspace data residency, input transformations, and web fetch tools, alongside client improvements.
READY TO POST:
anthropic's python sdk just dropped v1.6.0, adding 'auto mode tool permissions' for managed agents and new 'compaction' parameters. feels like better agent control is coming.
new anthropic python sdk update (v1.6.0) includes url_sources for the web fetch tool and new workspace data residency fields. nice to see continued tooling expansion.
