2.1.75

Added 1M context window for Opus 4.6 by default for Max, Team, and Enterprise plans, /color command to set prompt-bar colors, session name display on prompt bar, and last-modified timestamps to memory files. Fixed voice mode activation on fresh installs, Claude Code header not updating model name, session crashes with undefined attachments, Bash tool ! character handling in pipes, managed-disabled plugins appearing in plugin list, token estimation over-counting, corrupted marketplace config, /resume losing session names, and various UI issues. Improved startup performance on macOS and suppressed async hook completion messages by default (visible with --verbose).
