v3.0.0-0

• Breaking change: Now requires at least Node.js 8.x (somewhat following the LTS of Node.js itself)
• Breaking change: Now defaults to both engine and module version checks
• Breaking change: Engine check and module check is now treated as equals. --no-version-check opt-out has been replaced with --version-check opt-in
• Internal: Core functionality has been moved to installed-check-core, this module now just contains the CLI
