Claude Code v2.1.174 の更新内容

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
