Claude Code now detects and supports a broader range of terminal emulators on all platforms for launching new terminal sessions (used by deep links and remote sessions). On Windows, it prioritizes Windows Terminal, then PowerShell 7+, PowerShell 5, and Command Prompt. On macOS and Linux, it detects Ghostty, iTerm2, Alacritty, Kitty, WezTerm, and various others with proper --working-directory flag support.
