Claude Code (Anthropic's terminal coding agent)
- Latest version: v2.1.162 (released 3 hours ago)
- Key updates:
claude agents --json now includes waitingFor field showing what a waiting session is blocked on (e.g., permission prompt)
- --tools: explicitly listing Grep/Glob now provides dedicated search tools on native builds with embedded search (previously ignored)
- /effort command now confirms when your chosen level will persist as the default for new sessions
- Clicking a slash command in the autocomplete menu fills it into your prompt instead of running immediately; press Enter to execute
- Remote Control now shows as a persistent footer pill (with session link) instead of a startup message
- Renamed Windsurf to Devin Desktop in /ide, /terminal-setup, and /scroll-speed menus following the editor's rebrand
- Fixed silent startup hang when config directory is read-only/unwritable — now starts with in-memory config and surfaces startup errors
- Fixed WebFetch permission rules not being applied to built-in preapproved domains; explicit WebFetch(domain:...) deny/ask/allow rules now take precedence over preapproved-host auto-allow
- Fixed Windows permission rules for backslash and case-variant paths; Read deny rules no longer hide files from Glob/Grep results
- Fixed interrupt (Esc) at start of turn being dropped in stream-json/SDK sessions
- Fixed API 400 "no low surrogate in string" errors for classifier side-queries and MCP server descriptions with emoji near truncation boundary
- Fixed MCP per-server timeout config values below 1000 ms being floored to 1-second watchdog; sub-1000 ms values now ignored (fallback to MCP_TOOL_TIMEOUT or default); claude mcp get annotates them
- Fixed LSP tool's workspaceSymbol operation returning no results; now accepts query parameter and passes to language server
- Fixed claude agents cutting live status text (tool args, replies, prompts, exec output) at 60–120 columns on wide terminals; now uses full terminal width
- Fixed claude agents truncating long session names at 40 columns; name column now grows with terminal width
- Fixed claude agents attach bouncing back to session list on first try after background-service restart
- Fixed claude agents Ctrl+V image paste doing nothing in dispatch input and session reply box; pasting with no image now shows a hint
- Fixed backgrounding a session with ← silently losing conversation when background service cannot start; session stays as failed row wakeable with Enter
