Laravel Lockout v6.0 is a major upgrade that expands the package from basic read-only mode to a full maintenance and access-control system. It now supports Laravel 11 and 12 and introduces 10 new features, including IP allow/deny lists with CIDR, role-based bypass rules, customizable responses, route and pattern whitelisting, automatic API handling, a health-check endpoint, configurable caching, a full event system, Artisan management commands, and a new maintenance view. With 77 tests, refined middleware, and improved code quality, v6.0 is production-ready and built for precise control during maintenance or emergencies.
