← Claude Code changelog

Claude Code 2.1.161

This release significantly enhances workflow reliability and user experience. Parallel tool calls now execute independently, ensuring a single failure won't halt other tasks in the same batch, and usage metrics can be sliced by custom dimensions like team or repo for deeper insights. Critical fixes address issues like managed-settings policies blocking third-party provider sessions, background output corruption, and `/autofix-pr` limitations in git worktrees. Overall, these improvements provide a more robust, secure, and insightful environment for all users, particularly those with complex workflows or specific enterprise configurations.

Added

  • Added a tip suggesting disabling terminal GPU acceleration (or running `/terminal-setup`) to fix garbled glyphs

Improved

  • Improved terminal rendering performance by stabilizing the layout engine's JIT compilation profile
  • Improved rendering performance for large file writes

Changed

  • `OTEL_RESOURCE_ATTRIBUTES` values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo
  • `claude agents` rows now show `done/total` before the detail when work is fanned out; peek shows the longest-running item
  • `/mcp` now collapses claude.ai connectors you've never signed in to behind a "Show unused connectors" row
  • Parallel tool calls: a failed Bash command no longer cancels other calls in the same batch — each tool returns its own result independently
  • Fullscreen mode: clipboard now uses `wl-copy`/`xclip`/`xsel` on Linux when available, copies to both the clipboard and PRIMARY selection for middle-click paste, and the "hold {key} for native selection" hint now shows the correct key per terminal

Fixed

  • Fixed the `/effort` dialog, workflow animations, and prompt keyword shimmer not honoring the "Reduce motion" setting
  • Fixed `forceLoginOrgUUID`/`forceLoginMethod` managed-settings policies blocking third-party provider sessions (Bedrock, Vertex, Foundry, Mantle) alongside the org pin (regression in 2.1.146)
  • Fixed background subagent output corrupting `claude -p` stdout when using `--output-format text` or `json`
  • Fixed `/usage-credits` starting a re-login for Team and Enterprise admins instead of pointing to the organization's usage settings page
  • Fixed `/autofix-pr` reporting "cannot run on the default branch" when the session is inside a git worktree or another repository
  • Fixed `--resume` picker not showing sessions from the current directory when it isn't a git worktree (e.g., jj workspaces)
  • Fixed Windows hooks that invoke bash explicitly (e.g., `/usr/bin/bash script.sh`) failing with "command not found" or "cannot execute binary file"
  • Fixed OpenTelemetry log events (`user_prompt`, `api_request`, `tool_result`, `tool_decision`) being silently dropped when emitted before telemetry initialization completed
  • Fixed `claude mcp` list/get/add printing secrets to the terminal: `${VAR}` references are no longer expanded, and credential headers and URL secrets are redacted
  • Fixed Workflow agents spawned with `isolation: "worktree"` in background sessions being blocked from editing files inside their own worktree
  • Fixed background sessions dispatched from `claude agents` booting on a stale model from the daemon's environment instead of the model in `settings.json`
  • Fixed a potential crash when rendering Write tool results after resuming a session
  • Fixed completed subagents getting stuck showing as running when an error occurs while finalizing their result
  • Fixed `EADDRINUSE` errors from tools that bind Unix sockets under `$TMPDIR` when `CLAUDE_CODE_TMPDIR` is set to a deep path
