## AI 摘要

Claude Code v2.1.191 新增 `/rewind` 命令，支持从 `/clear` 前恢复对话。修复流式响应时滚动位置跳到底部、后台智能体停止后复活等问题。改进 MCP 服务器可靠性，对 `tools/list` 等请求增加短暂退避重试；优化 OAuth 流程，无头环境直接跳过浏览器弹窗。流式响应 CPU 使用率降低约 37%（通过合并文本更新间隔至 100ms），并减少终端输出缓存带来的内存增长。

## 正文

What's changed

Added /rewind support for resuming a conversation from before /clear was run

Fixed scroll position jumping to the bottom while reading earlier output during a streaming response

Fixed background agents resurrecting after being stopped — stopping an agent from the tasks panel is now permanent

Fixed /voice showing a generic "not available" message when disabled by an organization's policy — it now explains the restriction

Fixed /login URL opening truncated in Windows Terminal when it wraps across lines

Fixed Cmd+click on links in fullscreen mode for Ghostty over ssh/tmux

Fixed claude agents sending builtin slash commands like /usage to background sessions as prompt text instead of showing a hint

Fixed claude agents job rows showing full filesystem paths for pasted images instead of the [Image #N] placeholder

Fixed hooks with comma-separated matchers (e.g. "Bash,PowerShell") silently never firing

Fixed /permissions Recently-denied tab: approving a denial now persists on close instead of being silently discarded

Fixed the agent panel jumping by one row when scrolling the roster past the overflow cap

Fixed the welcome splash art overflowing the default 80×24 macOS Terminal window

Fixed managed settings: forceRemoteSettingsRefresh now takes effect when set via MDM or file policy, and the fetch sends Cache-Control: no-cache to prevent proxies from serving stale responses

Improved sandbox network permission dialog: hosts you allow with "Yes" are now remembered for the rest of the session instead of re-prompting on every connection

Improved MCP server reliability: capability discovery (tools/list, prompts/list, resources/list) now retries transient network errors with short backoff

Improved MCP OAuth: discovery and token requests now retry once after transient network errors, and headless environments skip the browser popup and go straight to the paste-the-URL prompt

Improved MCP error messages: HTTP 404 errors now show the URL and point to your MCP config

Improved vim mode prompt-history search (NORMAL /) to hint how to reach slash commands

Reduced CPU usage during streaming responses by ~37% by coalescing text updates to 100ms

Reduced long-session memory growth from terminal output cache
