# Claude Code发布v2.1.221：新增Focus View隐藏工具活动

Claude Code 更新至 v2.1.221。主要变化：VSCode 新增 Focus View，通过 Ctrl+Alt+F 切换，将工具活动折叠为可展开摘要，并显示实时运行指示器；Linux 和 WSL 上新增 sandbox 凭据文件的 mask 模式。

## English Version

**Claude Code v2.1.221 Adds Focus View, Sandbox Mask Mode**

Claude Code v2.1.221 introduces Focus View in VSCode, a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator (Ctrl+Alt+F). Also adds 'mask' mode for sandbox credential files on Linux and WSL.
