[Release] anthropics/claude-code v2.1.175: v2.1.175

Claude Code v2.1.175 introduces the `enforceAvailableModels` managed setting, which strengthens model access control by constraining the Default model selection to the allowlist. When enabled, any Default model that resolves to a disallowed model automatically falls back to the first allowed model, and users cannot override the managed allowlist with broader settings.

Key Points

• •New `enforceAvailableModels` managed setting provides stricter model access governance
• •When enabled, the `availableModels` allowlist now constrains the Default model selection
• •Default models that resolve to disallowed models automatically fall back to the first allowed model in the list
• •User and project-level settings can no longer widen or override a managed `availableModels` list
• •Enhances security and compliance by preventing unauthorized model access escalation
• •Provides administrators with stronger control over model availability across teams
