Claude Code 2.1.191

This release introduces the highly requested /rewind command, enabling conversation resumption even after clearing the chat history. Key improvements include a fix for scroll position jumping during streaming responses and significant CPU usage reduction (up to 37%) during text updates, ensuring a smoother experience. Agent management sees greater reliability with permanent agent stopping, while sandbox network permissions are now remembered per session, enhancing developer workflow. Various other fixes address usability, agent display, and policy enforcement, benefiting all users with a more stable and efficient environment.

Added

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

Improved

  • 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

Changed

  • Reduced CPU usage during streaming responses by ~37% by coalescing text updates to 100ms
  • Reduced long-session memory growth from terminal output cache

Fixed

  • 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
