TL;DR: Anthropic's Claude Code 2.1.271 lands with faster remote responses, tighter per-command network sandboxing, and immediate org-policy refresh after credential switches.
Summary: Claude Code 2.1.271 has been released with 96 CLI changes. Claude Code Remote now honors the host's fast-mode setting (or /fast), reducing response latency where the organization permits it, and auto-sandboxing for Bash, PowerShell, and Monitor can be constrained with per-command allowed_domains so only required hosts are reachable. The org-policy cache is also cleared when switching accounts or API keys, so updated policies apply immediately instead of going stale.
Why it matters: Sandbox egress controls and instant policy propagation matter for teams running agents in regulated or locked-down environments, where stale rules or unrestricted network access are real risks. Upgrade and audit your allowed_domains lists if you run Claude Code with auto-sandboxing enabled.
