Claude Code 2.1.75: Opus 4.6 Context, Voice Fixes

Claude Code 2.1.75 brings 1M context for Opus 4.6 by default, fixes voice mode activation, and patches Bash tool issues. One breaking change for Windows managed settings paths.

Claude Code 2.1.75: Opus 4.6 Context, Voice Fixes

TL;DR

  • 1M context window for Opus 4.6 now default on Max/Team/Enterprise (no extra usage cost)
  • Voice mode activation fixed on fresh installs; Bash tool no longer mangles `!` in piped commands
  • Breaking change: Windows managed settings path moved to `C:\Program Files\ClaudeCode\managed-settings.json`

New

  • /color command — set a custom prompt-bar color for your session
  • Session name display — prompt bar now shows your session name when using `/rename`
  • Memory timestamps — last-modified dates added to memory files so Claude can distinguish fresh vs. stale context
  • Hook source visibility — permission prompts now display where a hook comes from (settings/plugin/skill)

Fixed

  • Voice mode activation — no longer requires toggling `/voice` twice on fresh installs
  • Model name display — Claude Code header now updates correctly after `/model` or Option+P switches
  • Session crashes — fixed crash when attachment message computation returns undefined values
  • Bash tool `!` handling — piped commands like `jq 'select(.x != .y)'` now work correctly
  • Managed-disabled plugins — organization force-disabled plugins no longer appear in `/plugin` Installed tab
  • Token estimation — fixed over-counting for thinking and `tool_use` blocks, preventing premature context compaction
  • Marketplace config — fixed corrupted path handling
  • /resume behavior — session names no longer lost after resuming forked or continued sessions
  • Dialog closing — Esc now properly closes `/status` dialog after Config tab visit
  • Plan acceptance — fixed input handling when accepting or rejecting a plan
  • Footer hint — agent teams footer now shows correct "shift + ↓ to expand" instead of "↓ to expand"
  • macOS startup — improved performance on non-MDM machines by skipping unnecessary subprocess spawns

Breaking Changes

  • Windows managed settings path changed from `C:\ProgramData\ClaudeCode\managed-settings.json` to `C:\Program Files\ClaudeCode\managed-settings.json` — update any automation or deployment scripts
