Anthropic releases Claude Code v2.1.71 with Claude API skill, expanded Voice STT language support, enhanced VS Code integration, and numerous improvements.

Anthropic released Claude Code v2.1.71 on March 6, 2026. This major update introduces new features centered around developer experience and external application integration.

Key Changes

UX Improvements

Effort Level Display: Effort level (e.g., “with low effort”) is now displayed on the logo and spinner, making it easier to verify the current effort setting.

Agent Name Display: When using --agent, the agent name now appears in the terminal title.

VS Code Integration Enhancement

MCP Server Management Dialog: Users can now enable/disable MCP servers, reconnect, and manage OAuth authentication using the /mcp command in the chat panel without switching to the terminal.

Security Improvements

Skill Loading Security Fix: Fixed a security issue where nested skill discovery could load skills from gitignored directories like node_modules.

Added optional name argument to /remote-control for custom session titles
Added numeric keypad support for option selection
Added sandbox.enableWeeperNetworkIsolation setting for TLS certificate verification with custom MITM proxies
Added includeGitInstructions setting to disable built-in commit/PR workflow instructions

Added ${CLAUDE_SKILL_DIR} variable for skills to reference their own directory

Bug Fixes

Fixed claude remote-control crashing on npm installs
Fixed deprecated Opus model versions resolving to current versions
Fixed macOS keychain corruption issue
Fixed .credentials.json subscription type display issues
