Claude Code 2.1.141 - リリースノート

日本語サマリー

ご提示いただいたリリースノートの要約です。破壊的変更やセキュリティ関連の重要な修正は見当たりませんでしたが、認証や権限まわりの重要な変更を冒頭にまとめています。

⚠️ 重要な変更・修正

• サードパーティプロバイダーの認証修正: Bedrock, Vertex, Foundryなどサードパーティプロバイダーのセッションが、ホストの apiKeyHelper / ANTHROPIC_AUTH_TOKEN を誤って継承していた問題を修正しました。
• AWS認証の修正: 環境のAWS認証情報が検出された場合に awsCredentialExport がスキップされ、クロスアカウントアクセスの認証に失敗していた問題を修正しました。

✨ 新機能と主な変更点

• フック機能の拡張: HookのJSON出力に terminalSequence フィールドが追加され、制御端末なしでデスクトップ通知やベルの発行などが可能になりました。
• 新規環境変数の追加:
  • CLAUDE_CODE_PLUGIN_PREFER_HTTPS: SSH鍵がない環境向けに、GitHubプラグインのソースをHTTPS経由でクローンできるようになりました。
  • ANTHROPIC_WORKSPACE_ID: 複数のワークスペースをカバーする連合ルール（Federation）で、特定のワークスペースにトークンをスコープするために追加されました。
• claude agents の改善: 特定ディレクトリにセッションリストを絞り込む --cwd <path> オプションが追加されました。
• コンテキストの圧縮: Rewindメニューに「Summarize up to here」が追加され、最新のやり取りを残しつつ以前のコンテキストを要約・圧縮できるようになりました。
• フィードバック機能の強化: /feedback で現在のセッションだけでなく、過去24時間または7日間の recent sessions を含められるようになりました。
• 権限とバックグラウンド処理の改善:
  • Autoモードの権限ダイアログが、permissions.ask ルールによる表示理由を説明するようになりました。
  • /bg や ←← で起動したバックグラウンドエージェントが、デフォルトに戻らず現在の権限モードを維持するようになりました。

🐛 主要なバグ修正

• モデル・プロバイダー関連: ANTHROPIC_SMALL_FAST_MODEL 未設定時、Bedrock/Vertexなどで利用できないHaikuモデルIDが送信される背景クエリの問題を修正（メインモデルにフォールバック）。
• MCPサーバー関連: 認証エラー（403/401）の表示改善や、設定変数未設定時のエラーメッセージ改善、POSIXシェルの変数展開（${var%pattern}）の誤検知修正など、多数のMCP関連修正を含みます。
• UI/操作感の改善: 権限プロンプト表示中の Enter キー誤送信、/model の同時セッション閾値への副作用、Ctrl+C による中断が効かない問題、light-ansiテーマでの差分コンテキストが見えなくなる問題などを修正しました。
• Windows/WSL: Windowsでのデーモンパイプキーのロックエラー表示改善や、WSLgユーザー向けの音声モード依存パッケージ（sox など）の提案追加、Alt+Vでの画像貼り付けエラーを修正しました。

原文（Release Notes）

What's changed

• Added terminalSequence field to hook JSON output so hooks can emit desktop notifications, window titles, and bells without a controlling terminal
• Added CLAUDE_CODE_PLUGIN_PREFER_HTTPS to clone GitHub plugin sources over HTTPS instead of SSH, for environments without a GitHub SSH key
• Added ANTHROPIC_WORKSPACE_ID environment variable for workload identity federation — scopes the minted token to a specific workspace when the federation rule covers more than one
• Added claude agents --cwd <path> to scope the session list to a directory
• /feedback can now include recent sessions (last 24 hours or 7 days) for issues spanning more than the current session
• Rewind menu: added "Summarize up to here" to compress earlier context while keeping recent turns intact
• Auto mode permission dialog now explains when a permissions.ask rule caused the prompt
• Restored the "view diff in your IDE" option on file-edit permission prompts when an IDE is connected
• Background agents launched via /bg or ←← now preserve the current permission mode instead of reverting to default
• claude agents: agents that finish work but leave a background shell running now move to Completed instead of staying under Working
• Improved spinner feedback during long thinking periods — the spinner now warms to amber after 10 seconds to signal Claude is still working
• Improved plugin menu navigation: →/Tab switch tabs, ↑ moves to the tab strip, and tab headers and search box are clickable in fullscreen mode
• Fixed background side-queries sending an unavailable Haiku model ID on Bedrock/Vertex/Foundry/gateway when no ANTHROPIC_SMALL_FAST_MODEL override is set — now falls back to the main-loop model
• Fixed claude daemon status and /doctor on Windows throwing when the daemon pipe key file is locked or unreadable — now shows the underlying error instead of an opaque failure
• Fixed claude agents showing the agent-type list instead of the dashboard when launched through a wrapper that adds flags
• Fixed claude agents opening a crashed session firing redundant dispatches when the working directory was deleted
• Fixed background jobs on a custom ANTHROPIC_BASE_URL gateway not getting auto-named — the namer now uses the main model when no Haiku model is configured
• Fixed /model in one session silently changing the autocompact threshold in other concurrent sessions
• Fixed switching permission mode while a tool-permission prompt is open not auto-dismissing the prompt when the new setting permits the tool
• Fixed pressing Enter while a permission/dialog prompt is open also submitting text in the input box
• Fixed hooks receiving a non-existent transcript_path after EnterWorktree switches the working directory
• Fixed markdown tables with cell wrapping falling back to the vertical key-value layout instead of rendering as a bordered grid (regression in 2.1.136)
• Fixed cancelled prompts being removed from Up-arrow history when auto-restored into the input box, avoiding duplicate entries
• Fixed prompts cancelled with Ctrl+C/Esc before any response being dropped from Up-arrow history
• Fixed Ctrl+C not interrupting a running turn while in vim INSERT/VISUAL mode
• Fixed alternative chat:submit keybindings (e.g. meta+enter, ctrl+enter) not working when enter is rebound to chat:newline
• Fixed prompt suggestions being silently disabled when an output style was configured
• Fixed spinnerVerbs setting not being honored in turn-completion messages
• Fixed AskUserQuestion popup hiding the last line of preceding chat content
• Fixed Web Search status showing "Did 0 searches" when searches returned errors
• Fixed multi-line statusline output dropping or corrupting rows when any line exceeds terminal width
• Fixed light-ansi theme using invisible white for diff context lines on light backgrounds — now uses black
• Fixed error overlay dumping minified bundle source that hid the original error message
• Fixed pressing Enter after typing a feedback survey rating digit submitting it as a chat message instead of the rating
• Fixed pressing x on a selected subagent in the agent panel typing into the prompt instead of stopping the agent
• Fixed session title being derived from plugin monitor notifications before the user's first prompt
• Fixed "Allowed by PermissionRequest hook" repeating once per tool call under a collapsed read/search group
• Fixed /tui silently dropping running background shells and subagents — now refuses and asks to wait for them to finish
• Fixed welcome banner showing "API Usage Billing" on Bedrock, Vertex, Foundry, and other third-party providers — now shows the provider name
• Fixed /mcp server list not keeping the focused server visible in short terminals in fullscreen mode
• Fixed redaction in /feedback bundles producing invalid JSON for quoted values like session IDs
• Fixed desktop and third-party provider sessions incorrectly inheriting apiKeyHelper/ANTHROPIC_AUTH_TOKEN from host managed-settings
• Fixed early analytics events being silently dropped when fired before logger initialization
• Fixed claude plugin install failing for plugins whose marketplace ref no longer exists upstream when a sha is also pinned
• Fixed plugin details pane showing 0 MCP servers for plugins that declare them via .mcp.json
• Fixed plugin MCP servers with unset config variables showing a generic connection failure instead of a "config issue" message with a fix-it hint; malformed .mcp.json entries no longer drop other MCP servers
• Fixed MCP server configs using POSIX shell parameter expansions (e.g. ${var%pattern}) being incorrectly flagged as missing environment variables
• Fixed MCP HTTP/SSE servers returning 403 on connect showing as "failed" instead of "needs auth"
• Fixed remote MCP servers disconnecting unnecessarily when the optional server-events stream failed to reconnect — tool calls continue over POST
• Fixed Remote Control MCP connectors all failing with 401 when the worker session token rotated mid-session
• Fixed Remote Control automatically re-enrolling a trusted device when the server rejects a stale token, instead of looping through /login
• Fixed a race where early OTel spans could be silently dropped in SDK/headless mode with beta tracing enabled
• Fixed custom voice:pushToTalk keybindings and "space": null unbinds being silently ignored
• Fixed Windows Alt+V image paste reporting "no image found" when the clipboard contains a screenshot
• Fixed SDK "Claude Code native binary not found" on Linux when both glibc and musl platform packages are installed
• Bedrock: awsCredentialExport now always runs when configured instead of being skipped when ambient AWS credentials resolve, fixing auth for cross-account access
• [VSCode] Fixed in-chat mic showing no feedback when the microphone produced only silence — now shows "No audio detected"
• [VSCode] Voice mode: the WSL error now suggests installing sox libsox-fmt-pulse for WSLg users
• claude agents: launching a session no longer fails when the pre-warmed background worker is unhealthy — now falls back to a fresh launch
• claude agents no longer shows empty placeholder sessions left over from backgrounding a fresh REPL, and shows onboarding text when entered via ← with no other agents
• Empty idle background sessions left over from ← are now automatically retired by the daemon after 5 minutes
