Download Claude Code 2.1.75

- Added 1M context window for Opus 4.6 by default for Max, Team, and Enterprise plans (previously required extra usage)
- Added /color command for all users to set a prompt-bar color for your session
- Added session name display on the prompt bar when using /rename
- Added last-modified timestamps to memory files, helping Claude reason about which memories are fresh vs. stale
- Added hook source display (settings/plugin/skill) in permission prompts when a hook requires confirmation
- Fixed voice mode not activating correctly on fresh installs without toggling /voice twice
- Fixed the Claude Code header not updating the displayed model name after switching models with /model or Option+P
- Fixed session crash when an attachment message computation returns undefined values
- Fixed Bash tool mangling ! in piped commands (e.g., jq 'select(.x != .y)' now works correctly)
- Fixed managed-disabled plugins showing up in the /plugin Installed tab — plugins force-disabled by your organization are now hidden
- Fixed token estimation over-counting for thinking and tool_use blocks, preventing premature context compaction
- Fixed corrupted marketplace config path handling
- Fixed /resume losing session names after resuming a forked or continued session
- Fixed Esc not closing the /status dialog after visiting the Config tab
- Fixed input handling when accepting or rejecting a plan
- Fixed footer hint in agent teams showing "↓ to expand" instead of the correct "shift + ↓ to expand"
- Improved startup performance on macOS non-MDM machines by skipping unnecessary subprocess spawns
- Suppressed async hook completion messages by default (visible with --verbose or transcript mode)
- Breaking change: Removed deprecated Windows managed settings fallback at C:\ProgramData\ClaudeCode\managed-settings.json — use C:\Program Files\ClaudeCode\managed-settings.json
