# Claude Code v2.1.203 发布：修复大量背景会话与子代理稳定性问题

## AI 点评

> 这个补丁版本几乎把 Claude Code 用户在过去几周遇到的所有顽固 bug 都修了，尤其是背景会话和子代理的稳定性。如果你正在用它做长时间运行的任务或多仓库开发，这个版本必须升级。

## 速览

Anthropic 发布 Claude Code v2.1.203，重点修复了背景会话的登录过期警告、手动权限模式徽章、MCP 根目录支持等新特性，同时解决了 macOS 上因错误内存检测导致的 15-20 秒卡顿、后台代理因令牌过期永久无响应、子代理工作丢失、交互式会话每轮 CPU/内存回归等关键问题，并优化了响应流畅度和二进制体积。

## 关键点

- 新增登录即将过期警告和手动权限模式徽章，提升会话可见性
- 修复 macOS 背景代理会话 15-20 秒卡顿和后台令牌过期导致永久无响应
- 修复子代理工作丢失、进程间环境变量继承、多仓库工作树隔离等核心问题
- 优化实时预览更新、减少二进制体积约 7MB、降低启动内存约 7MB

What's changed Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible Added the session's additional working directories to MCP roots/list, with notifications/roots/list_changed sent when the set changes Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196) Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically Fixed returning to claude agents silently stopping running subagents and re-running the prompt from scratch — their work now carries over Fixed a memory and per-turn CPU regression in interactive sessions: the context-usage indicator no longer re-analyzes the entire transcript after every turn Fixed background agents inheriting a stale PATH from the daemon instead of the dispatching shell, causing missing tools on Windows Fixed background and agent-view sessions dropping a shell-exported ANTHROPIC_BASE_URL, which sent API keys to the default endpoint and failed with 401 Fixed Bash failing with "argument list too long" in repos with many git worktrees Fixed worktree-isolated subagents sometimes running shell commands in the parent checkout instead of their own worktree Fixed worktree creation rejecting nested repositories in multi-repo workspaces, leaving background sessions unable to isolate and edit Fixed background agents crash-looping when their working directory was deleted, replaced by a file, or became an invalid path — they now fail once with a clear error Fixed a background daemon auto-upgrade failure silently killing all running background sessions Fixed TaskStop and TaskOutput failing to find background agents spawned by another agent — errors now list running agents by id and description Fixed the claude agents composer discarding your typed message when a slash command isn't available there Fixed the agent list crashing when opening a stopped session whose conversation was already open in another session Fixed background sessions showing "Needs input" in the agent list after the question was already answered Fixed background agent startup failures showing only "exit_with_message" instead of the actual error Fixed background sessions ignoring effortLevel changes in settings.json when forked through the daemon Fixed attached background sessions ignoring CLAUDE_CODE_DISABLE_MOUSE and CLAUDE_CODE_DISABLE_MOUSE_CLICKS opt-outs Fixed /exit incorrectly warning about running background agents after all named agents had completed Fixed background sessions started from a non-git directory unable to edit files when a WorktreeCreate hook was configured Fixed the @ directory picker in claude agents not showing registered git worktrees Fixed background task output on Windows being permanently replaced by an empty file after /clear Fixed content jumping when scrolling up through long transcript history Fixed the terminal flickering and jumping while typing in bash mode when a shell-history suggestion was shown Fixed literal ^[[I / ^[[O escape codes being printed when reattaching to a background session Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead Changed the empty claude agents view to always show the organized sections (Needs input / Working / Completed) with descriptions Removed the startup "claude command missing or broken" warnings — they now appear in /doctor and /status instead Removed a redundant navigation hint from the claude agents footer [VSCode] Added a Settings toggle for "Enable Remote Control for all sessions"
