ดาวน์โหลด Claude Code 2.1.219

- Added Claude Opus 5 (claude-opus-5), now the default Opus model — 1M context, fast mode at $10/$50 per Mtok
- Added sandbox.network.strictAllowlist setting to deny non-allowlisted hosts for sandboxed commands without prompting
- Added DirectoryAdded hook that fires after /add-dir or the SDK register_repo_root control request registers a new working directory mid-session
- Added mcp_server_errors to the headless stream-json init event, listing --mcp-config entries skipped by config validation; terminal runs print a startup warning
- Added the workflowSizeGuideline settings key so the advisory Dynamic workflow size guideline can be set from any settings file; the /config row is hidden while one does
- Added nested subagent forwarding in stream-json: subagents spawned at depth-2+ now appear when --forward-subagent-text is set, keyed by their spawning Agent tool_use id
- Fixed claude -p text output dropping the answer already produced when a turn dies on a mid-stream API error
- Added HTTP status and error text to claude mcp list and /mcp when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
- Fixed a permission you approved while a self-hosted runner was restarting being dropped when the session resumed, so the approved action now runs
- Fixed the Fable model row showing "Requires usage credits" for plans that include it, when a stale cache had baked the label in
- Fixed a SIGTERM arriving while a self-hosted runner was starting up leaving a stale active row until the lease expired; it now deregisters cleanly
- Added structured failure categories to self-hosted runner spawn and session failures, so hook errors, runner crashes and config errors can be told apart
- Fixed the /model picker showing the merged Opus row as plain "Opus" instead of "Opus (1M context)"
- Fixed copy-on-select inside GNU screen printing base64 into the terminal instead of copying the selection
- Fixed Remote Control clients keeping a stale fast-mode status after a model switch, reconnect, or failed org check
- Fixed CLAUDE_CODE_GIT_BASH_PATH on Windows exiting or being used as bash when the path isn't a bash/sh binary; it's now ignored with a warning
- Fixed Vim mode: pressing ← on an empty prompt now returns to the agent view from NORMAL mode, not just INSERT
- Fixed screen-reader mode rewriting the entire input line on every keystroke instead of echoing only the typed character
- Improved the "Remote Control is only available via api.anthropic.com" error to name the specific setting that caused it
- Improved claude --teleport to show which repo your current checkout points at when it doesn't match the session's repo
- Changed dynamic workflows to default to a medium size guideline (aim for fewer than 15 agents); pick another size or unrestricted with Dynamic workflow size in /config
- Changed managed MCP allowlist/denylist ${VAR} entries to resolve from the startup environment and managed-settings env instead of settings-file env
- Changed the /model picker to highlight only the newest model's name, so the highlight marks the new release rather than an arbitrary subset of the list
- Added the current default workflow size to the running-workflow status line, with a pointer to /config for changing it
- Removed Opus 4.7 from fast mode; /fast now applies to Opus 5 and Opus 4.8
- Updated the claude-api skill to default to Claude Opus 5, with a migration path from Opus 4.8
- Subagents can now spawn nested subagents up to depth 3 by default (was 1); set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH=1 to disable nesting
