Claude Code v2.1.174 Release Notes

Claude Code v2.1.174 is now available, delivering enhanced user experience improvements and critical bug fixes that make your AI-powered development workflow even more reliable and intuitive.

What’s New

Enhanced Scroll Control

New scroll acceleration setting: Added wheelScrollAccelerationEnabled setting to disable mouse-wheel scroll acceleration in fullscreen mode, giving you more precise control over navigation.

Improved Model Selection

Better model picker visibility: Fixed the /model picker to properly display model families that Default resolves to:
- Opus now appears as its own row on Max/Team Premium/Enterprise plans
- Sonnet displays correctly on Pro/Team plans
- Opus shows properly on pay-as-you-go API accounts
Accurate version labels: Fixed hardcoded Sonnet version labels when ANTHROPIC_DEFAULT_SONNET_MODEL pins a different Sonnet version

Enterprise & API Improvements

Billing banner fix: Resolved incorrect “Fable 5 is now consuming usage credits” banner showing for enterprise accounts with usage-based billing
Bedrock GovCloud support: Fixed Bedrock GovCloud regions (us-gov-*) to use correct inference profile prefix (us-gov instead of global), eliminating 400 errors
Background session isolation: Fixed background sessions inheriting incorrect ANTHROPIC_* provider environment variables from the shell daemon

Performance & Reliability Fixes

Faster exit times: Eliminated 1-2 second pause when exiting Claude Code after interrupted shell commands on macOS and Linux
Accurate git attribution: Fixed git commit co-author attribution displaying incorrect model names
Better advisor selection: Fixed /advisor dialog pre-selecting blocked advisor models from the availableModels allowlist
Optimized skill reloading: Skill hot-reload now only re-announces changed skills instead of the entire listing
Subagent attribution: Fixed missing per-agent attribution headers in Workflow tool agent() subagents

VSCode Integration

Enhanced usage tracking: Added comprehensive usage attribution to the Account & usage dialog (/usage) with detailed breakdowns:
- Cache misses and long context usage
- Subagent activity
- Per-skill, agent, plugin, and MCP usage statistics
- 24-hour and 7-day reporting periods
