Claude Code 重度用户终于不用再被模型选择器迷惑了——Opus/Sonnet 现在正确显示，背景会话的诡异环境变量问题也修了，建议所有使用 Claude Code 的开发者更新。
Anthropic 发布了 Claude Code v2.1.174 版本，主要修复了多个影响用户体验的 Bug。其中包括 /model 选择器不再隐藏 Default 解析的模型家族，Opus、Sonnet 等模型现在会正确显示；修复了背景会话继承错误环境变量导致的问题；修复了 macOS/Linux 上退出时 1-2 秒的卡顿；修复了 git 提交 co-author 显示错误模型名的问题。此外，新增了 wheelScrollAccelerationEnabled 设置以禁用全屏模式下的鼠标滚轮加速，VSCode 版本也增加了使用量归因面板。
v2.1.174
What's changed Added wheelScrollAccelerationEnabled setting to disable mouse-wheel scroll acceleration in fullscreen mode Fixed the /model picker hiding the model family that Default resolves to — Opus now appears as its own row on Max/Team Premium/Enterprise plans, Sonnet on Pro/Team plans, and Opus on pay-as-you-go API accounts Fixed /model picker showing a hardcoded Sonnet version label when ANTHROPIC_DEFAULT_SONNET_MODEL pins a different Sonnet Fixed the "Fable 5 is now consuming usage credits" banner incorrectly showing for enterprise accounts with usage-based billing Fixed Bedrock GovCloud regions ( us-gov-* ) deriving the wrong inference profile prefix ( global instead of us-gov ), causing 400 errors on derived model IDs Fixed background sessions inheriting another session's ANTHROPIC_* provider env (gateway URL, custom headers, /model aliases) from the shell that started the background daemon Fixed a 1-2 second pause when exiting Claude Code shortly after a shell command was interrupted or killed on macOS and Linux Fixed git commit co-author attribution showing an incorrect model name for some models Fixed the /advisor dialog pre-selecting a saved advisor model that is blocked by the availableModels allowlist Fixed skill hot-reload re-sending the entire skill listing when a single skill changed; only changed skills are now re-announced Fixed Workflow tool agent() subagents missing per-agent attribution headers [VSCode] Added usage attribution to the Account & usage dialog ( /usage ) showing cache misses, long context, subagents, and per-skill/agent/plugin/MCP breakdowns over the last 24h or 7d Fixed pre-warmed background workers failing with "Could not resolve authentication method" when claimed after sitting idle
