[Release] anthropics/claude-code v2.1.214: v2.1.214

ashwin-antJul 18, 2026

Claude Code v2.1.214 is a security and stability release that fixes critical permission-check bypasses across multiple shells (Bash, PowerShell, zsh), improves command parsing to prevent auto-approval of unsafe operations, and adds new features like the EndConversation tool and OpenTelemetry enhancements. The release addresses 50+ bugs including permission prompt timing issues, background session management, streaming failures, and platform-specific encoding problems on Windows.

  • Fixed permission-check bypass in Windows PowerShell 5.1 and improved Bash permission checks to fail closed on file-descriptor redirects and very long commands (>10,000 chars)
  • Enhanced permission prompts to prevent auto-approval of unsafe `help`, `man`, and `docker` daemon-redirect commands that could execute dangerous options or substitutions
  • Added EndConversation tool allowing Claude to terminate sessions with abusive users or jailbreak attempts, matching claude.ai behavior since 2025
  • +7 more key points...
