Claude Code v2.1.161: OTEL Labels, Parallel Tool Call Resilience, Linux Clipboard Overhaul
Anthropic
Claude Code v2.1.161 (released June 2, 2026) adds OTEL_RESOURCE_ATTRIBUTES values as metric labels for slicing usage by team and repo dimensions, improves the `claude agents` display to show done/total counts during fan-out, and collapses unused MCP claude.ai connectors by default. Key reliability fix: failed Bash commands in a parallel tool batch no longer cancel other in-flight calls. Linux fullscreen clipboard now uses wl-copy/xclip/xsel and supports both clipboard and PRIMARY selection. Additional bug fixes address managed-settings policy interference with third-party providers and background subagent stdout corruption.
Почему это важно
The parallel tool call resilience fix is critical for complex agentic workflows where a single failing Bash command previously aborted the entire batch, causing silent data loss in multi-step pipelines.
