 # Changelog
 
+## 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
+
 ## 2.1.218
 
 - Changed `/code-review` to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target
 - Added screen-reader announcements of deleted text for word and line deletions (`Option+Delete`, `Ctrl+W`, `Cmd+Backspace`, `Ctrl+U`, `Ctrl+K`) in `--ax-screen-reader` mode
 - Fixed Windows paths with `\u`-prefixed segments (like `C:\Users\unicorn`) being corrupted into CJK characters in tool inputs, which made those files inaccessible
 - Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ask to confirm, and Esc in the agent view returns to the conversation it backgrounded
-- 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 multi-line paste collapsing into one line with `j` in place of newlines in terminals that encode pasted newlines as Ctrl+J
 - Fixed `/context` reporting stale pre-compact token usage after compacting from the message picker
 - Fixed `/ultrareview` failing on descriptive arguments like "review my auth changes" — they now run a review of your current branch with the text applied as a note to the findings

-    <content type="html">&lt;p&gt;• Subagents now run in the background by default, so Claude keeps working while they run and is notified when they finish (previously a gradual rollout)&lt;/p&gt;
-&lt;p&gt;• Claude in Chrome is now generally available&lt;/p&gt;
-&lt;p&gt;• Added background agent notifications in claude agents — sessions that need input or finish now fire the Notification hook (agent_needs_input / agent_completed)&lt;/p&gt;
-&lt;p&gt;• Added /dataviz skill for chart and dashboard design guidance with a runnable color-palette validator&lt;/p&gt;
-&lt;p&gt;• Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain&lt;/p&gt;
-&lt;p&gt;• Background agents launched from claude agents now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask&lt;/p&gt;
-&lt;p&gt;• The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku&lt;/p&gt;
-&lt;p&gt;• Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks&lt;/p&gt;
-&lt;p&gt;• Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing&lt;/p&gt;
-&lt;p&gt;• Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host&lt;/p&gt;
-&lt;p&gt;• Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session&lt;/p&gt;
-&lt;p&gt;• Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately&lt;/p&gt;
-&lt;p&gt;• Fixed the /diff panel not refreshing when you switch branches or commit outside the session&lt;/p&gt;
-&lt;p&gt;• Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode&lt;/p&gt;
-&lt;p&gt;• Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — awsAuthRefresh now runs automatically&lt;/p&gt;
-&lt;p&gt;• Fixed "no route to host" for local-network hosts in macOS background agent sessions by declaring Local Network entitlements&lt;/p&gt;
-&lt;p&gt;• Fixed /desktop failing with "Cannot determine working directory" after entering and exiting a worktree&lt;/p&gt;
-&lt;p&gt;• Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open&lt;/p&gt;
-&lt;p&gt;• Fixed pressing ← inside claude attach &amp;lt;id&amp;gt; exiting to the shell instead of opening the agent view&lt;/p&gt;
-&lt;p&gt;• Fixed claude --bg silently creating an unattachable session when combined with --print/-p; the conflicting flags are now rejected up front&lt;/p&gt;
-&lt;p&gt;• Fixed the workflow progress view dropping the earliest agents from the list while the phase counter stayed correct in SDK and desktop-app sessions&lt;/p&gt;
-&lt;p&gt;• Fixed .claude/rules/ conditional rules not loading when the target file is reached via a symlinked path&lt;/p&gt;
-&lt;p&gt;• Fixed Cmd+click not opening URLs in fullscreen mode in Warp on macOS&lt;/p&gt;
-&lt;p&gt;• Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme&lt;/p&gt;
-&lt;p&gt;• Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode&lt;/p&gt;
-&lt;p&gt;• Fixed /branch deriving its default fork name from the compaction summary instead of the first real prompt&lt;/p&gt;
-&lt;p&gt;• Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count&lt;/p&gt;
-&lt;p&gt;• Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11&lt;/p&gt;
-&lt;p&gt;• Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH&lt;/p&gt;
-&lt;p&gt;• Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded&lt;/p&gt;
-&lt;p&gt;• /login now opens the sign-in dialog from the claude agents view instead of saying it isn't available&lt;/p&gt;
-&lt;p&gt;• Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval&lt;/p&gt;
-&lt;p&gt;• Removed the /agents wizard; ask Claude to create or manage subagents, or edit .claude/agents/ directly&lt;/p&gt;</content>
