2.1.257

(☝ Click to see full diff.)

Highlights:

  • Default Fable model set to Claude Fable 5.1 (1M context); billing now $10/$50 per Mtok, $0.25/Mtok cache reads
  • Auto mode prompts once before the first file read outside working directories, with an option to block reads
  • Auto mode blocks auto-approval of cloud metadata, egress evasion and cross-tenant reach—reducing exposure

CLI changelog

  • Added Claude Fable 5.1 (claude-fable-5-1), now the default Fable model — 1M context, $10/$50 per Mtok with $0.25/Mtok cache reads
  • Added "Time format" (timeFormat) and timeZone settings: 12-hour, 24-hour, 24-hour UTC, or a strftime pattern for the turn-end clock and transcript-view timestamps
  • Added a Containment Escape rule to auto mode so cloud metadata-credential fetches, egress evasion, and cross-tenant reach are no longer auto-approved unless your environment marks them expected
  • Added CLAUDE_CODE_SUBAGENT_MODEL_FORCE to apply CLAUDE_CODE_SUBAGENT_MODEL (or the main model) to every subagent, ignoring per-spawn and agent-definition model overrides
  • Added s in /effort to change effort for the current session only, matching /model
  • Added a /doctor warning for stale sandbox mask files left by a killed session
  • Added a one-time prompt in auto mode before the first file read outside the working directories, with the option to block such reads (permissions.blockReadsOutsideWorkingDirectories)
  • Added support for a gateway-supplied description on discovered /model picker entries (CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY); entries without one still read "From gateway"
  • Fixed settings in a .claude/ folder created after startup not being picked up until restart
  • Fixed sessions dispatched from an agent view opened with ← always starting in the original session's permission mode, overriding the target directory's defaultMode and the agent's permissionMode
  • Fixed keybindings.json rebinds of Ctrl+G being ignored in claude agents; its Ctrl+S / Ctrl+T are now rebindable via the new Agents context
  • Fixed background sessions failing to start on macOS npm installs during a self-update, and on Windows when a stale daemon lock file pointed at a reused process id
  • … +92 more CLI changelog entries
