✨ Claude Code v2.1.20 发布了！

✦ 更新内容
• 在 vim 普通模式下，当光标无法再继续移动时，新增方向键历史记录导航
• 在帮助菜单中新增外部编辑器快捷键（ Ctrl+G ），提升可发现性
• 在提示输入区底部新增 PR 审查状态指示器：用带颜色的小圆点展示当前分支 PR 状态（已批准 / 需要修改 / 待处理 / 草稿），并提供可点击链接
• 支持通过 --add-dir 参数指定额外目录来加载其中的 CLAUDE.md 文件（需设置 CLAUDE_CODE_ADDITIONAL_DIRECTORIES_CLAUDE_MD=1 ）
• 新增可通过 TaskUpdate 工具删除任务的能力
• 修复会话压缩（ compaction ）问题：此前可能导致恢复会话时加载完整历史，而不是压缩后的摘要
• 修复代理在执行任务期间，有时会忽略用户发送的新消息的问题
• 修复宽字符（ emoji 、中文/日文/韩文等）渲染瑕疵：宽字符被更窄字符替换时，尾部列未清除导致的残影
• 修复当 MCP 工具响应包含特殊 Unicode 字符时引发的 JSON 解析错误
• 修复在多行/自动换行文本输入中，按上下方向键时应优先移动光标而不是触发历史导航的问题
• 修复按上方向键浏览命令历史时，草稿输入内容会丢失的问题
• 修复在输入过程中键入斜杠命令时“幽灵文本”闪烁的问题
• 修复移除 marketplace 来源时未能正确删除设置的问题
• 修复某些命令（如 /context ）出现重复输出的问题
• 修复任务列表有时会显示在主对话视图之外的问题
• 修复在 Python 文档字符串等多行结构内出现 diff 时的语法高亮问题
• 修复取消工具调用时可能导致的崩溃
• 改进 /sandbox 命令 UI：当缺少依赖时显示依赖状态，并提供安装说明
• 改进“思考中”状态文本：增加细微的闪光（ shimmer ）动画效果
• 改进任务列表：根据终端高度动态调整可见条目数量
• 改进“分叉对话”提示：说明如何恢复原始会话
• 调整折叠的 read/search 分组显示：进行中用现在时（“Reading”“Searching for”），完成后用过去时（“Read”“Searched for”）
• 调整队友消息渲染：支持富 Markdown 格式（加粗、代码块、列表等），不再仅以纯文本显示
• 调整 ToolSearch 结果展示：改为简短通知，而不是内嵌在对话中
• 调整 /commit-push-pr 技能：当通过 MCP 工具配置后，可自动将 PR URL 发布到 Slack 频道
• 调整 /copy 命令：对所有用户开放
• 调整后台代理：启动前会先请求工具权限
• 调整权限规则：如 Bash(*) 将被接受并视作等同于 Bash
• 调整配置备份：新增时间戳并轮换保留（保留最近 5 份），以防止数据丢失

• Changed the /commit-push-pr skill to automatically post PR URLs to Slack channels when configured via MCP tools
• Changed the /copy command to be available to all users
