• /config key=value sets any setting from the prompt. Works in interactive, -p, and Remote Control, so you can script setting changes without editing JSON files.
• Prompt caching was silently broken on custom ANTHROPIC_BASE_URL and Foundry. A per-request attestation token changed every turn, defeating the cache entirely (more below).
• Foreground subagents now cap at the same 5-level depth as background subagents. Previously unbounded, so deep foreground chains will stop at 5 (more below).
• CLAUDE_CLIENT_PRESENCE_FILE suppresses mobile push notifications while you're at the machine. Point it at a marker file your presence detector creates and deletes.

New in 2.1.181

2.1.181 (June 18, 2026)

• Added /config key=value syntax to set any setting from the prompt (e.g. /config thinking=false), works in interactive, -p, and Remote Control
• Added sandbox.allowAppleEvents opt-in setting that lets sandboxed commands send Apple Events on macOS
• Added CLAUDE_CLIENT_PRESENCE_FILE environment variable: point it at a marker file to suppress mobile push notifications while you're at the machine
• Upgraded the bundled Bun runtime to 1.4
• Improved streaming of long paragraphs: text now appears line-by-line instead of waiting for the first line break
• Improved auto-retry: API connection drops mid-thinking now automatically retry instead of showing "Connection closed while thinking"
• Improved the subagent panel: idle subagents auto-hide after 30s, the list caps at 5 rows with scroll hints, and keyboard hints now show in the footer
• Improved the MCP OAuth browser page to match Claude Code's visual style and auto-close on success
• Changed fullscreen mode URL opening to require Cmd+click (macOS) / Ctrl+click, matching native terminal behavior
• Changed the Improved N memories line to no longer list individual files outside verbose mode
• Fixed prompt caching not reading on custom ANTHROPIC_BASE_URL and on Foundry due to a per-request attestation token changing every turn
• Fixed Write/Edit producing 0-byte or truncated files on network drives and cloud-synced folders
• Fixed open, osascript, and browser-based auth flows failing with error -600 on macOS by adding the Apple Events entitlement
• Fixed a startup regression (~120ms per launch in fresh environments, introduced in 2.1.169): the first prompt no longer waits for the managed-settings fetch when no MCP servers are configured
• Fixed startup blocking with a blank terminal for up to 15 seconds when the account settings fetch is slow on a degraded network
• Fixed startup crash (TypeError: Cannot read properties of null) when .claude.json contains corrupted null project entries
• Fixed macOS TUI freezing at session start (Ctrl+C unresponsive) when Spotlight is busy reindexing
• Fixed long-running idle sessions losing their history when another Claude Code process ran the 30-day transcript cleanup
• Fixed foreground subagents spawning unbounded nested chains; they now respect the same 5-level depth limit as background subagents
• Fixed /recap and conversation forks using the previous model immediately after a model switch
• Fixed subagent "Thinking" duration showing the parent agent's elapsed time instead of the subagent's own
• Fixed subagents blocked on a nested agent showing a ticking elapsed time instead of "waiting" in the agent panel
• Fixed the API retry indicator ("Retrying in 0s, attempt N/10") staying on screen after the retry succeeded
• Fixed AWS awsCredentialExport credentials with a short remaining lifetime causing credential refreshes every minute, and now accepts the JSON shape from aws configure export-credentials
• Fixed claude mcp get/list showing ✓ Connected when tools/list fails; they now show ! Connected, tools fetch failed with the error detail
• Fixed /remote-control leaving a stale "connecting..." line; it now confirms in the transcript once connected
• Fixed ExitWorktree refusing to remove a clean worktree with "Could not verify worktree state" when bare git cannot be resolved on Windows
• Fixed settings changes (such as /effort or /model) failing with ENOENT when ~/.claude/settings.json is a relative symlink under a symlinked ~/.claude
• Fixed IDE selection line numbers in context reminders being off by one (IntelliJ and VS Code)
• Fixed Ctrl+C in fullscreen after a native terminal selection (modifier+drag) overwriting the clipboard with the app's prior selection
• Fixed Ctrl+V showing "No image found in clipboard" instead of pasting when the clipboard contains text
• Fixed agent creation failing with "EEXIST: file already exists" when the agents directory already exists (Windows/OneDrive)
• Fixed AskUserQuestion preview content being cut off at the dialog edge instead of word-wrapping
• Fixed AskUserQuestion multi-select questions silently dropping a typed "Other" free-text answer when submitting
• Fixed /stats "Most active day" and daily token chart dates showing one day early in UTC-negative timezones
• Fixed /copy and copy-on-select on Linux not detecting a clipboard utility installed after Claude Code started
• Fixed tab-indented code rendering with incorrect indentation in the Write (create-file) preview
• Fixed user prompts queued mid-turn not showing a full-width background highlight in the transcript
• Fixed the activity spinner's pulse dwelling on the wrong glyph size in Ghostty
