+## 🆕 Recursos Principais v1.0.0
+
+### 🚀 Express.js-Inspired API
+
+**Familiar and Intuitive:**
+```php
+use PivotPHP\Core\Application;
+
+$app = new Application();
+
+// Routes
+$app->get('/users', function($req, $res) {
+    return $res->json(['users' => $userService->all()]);
+});
+
+$app->get('/users/:id', function($req, $res) {
+    $id = $req->param('id');
+    $user = $userService->find($id);
+    return $res->json(['user' => $user]);
+});
+
+$app->post('/users', function($req, $res) {
+    $data = $req->body();
+    $user = $userService->create($data);
+    return $res->status(201)->json(['user' => $user]);
+});
+
+$app->listen(3000);
+```
+
+### 🛡️ Comprehensive Security Suite
+
+**Built-in Security Middleware:**
+```php
+// CORS Protection
+$app->use(new CorsMiddleware([
+    'origin' => ['https://mydomain.com'],
+    'methods' => ['GET', 'POST', 'PUT', 'DELETE'],
+    'headers' => ['Content-Type', 'Authorization']
+]));
+
+// CSRF Protection
+$app->use(new CsrfMiddleware());
+
+// XSS Protection
+$app->use(new XssMiddleware());
+
+// JWT Authentication
+$app->use('/api', new AuthMiddleware([
+    'secret' => 'your-jwt-secret',
+    'algorithms' => ['HS256']
+]));
+```
+
+### ⚡ High-Performance Routing
+
+**Advanced Router Features:**
+```php
+// Parameter constraints
+$app->get('/users/:id<\\d+>', $handler);
+$app->get('/files/:filename<[a-zA-Z0-9_-]+\\.[a-z]{2,4}>', $handler);
+
+// Route groups
+$app->group('/api/v1', function($group) {
+    $group->get('/users', $usersHandler);
+    $group->post('/users', $createUserHandler);
+    $group->get('/users/:id', $userHandler);
+});
+
+// Middleware for specific routes
+$app->get('/admin/*', [new AuthMiddleware(), $adminHandler]);
+```
+
+### 🔧 Dependency Injection Container
+
+**Advanced DI System:**
+```php
+// Service registration
+$app->bind('database', function() {
+    return new PDO('mysql:host=localhost;dbname=app', $user, $pass);
+});
+
+// Service providers
+class DatabaseServiceProvider extends ServiceProvider
+{
+    public function register(): void
+    {
+        $this->app->bind('db', Database::class);
+    }
+    
+    public function boot(): void
+    {
+        // Boot logic
+    }
+}
+
+$app->register(new DatabaseServiceProvider());
+```
+
+### 📝 Middleware System
+
+**PSR-15 Compliant Middleware:**
+```php
+// Global middleware
+$app->use(new LoggingMiddleware());
+$app->use(new CompressionMiddleware());
+
+// Route-specific middleware
+$app->get('/users', [
+    new AuthMiddleware(),
+    new RateLimitMiddleware(100, 60), // 100 requests per minute
+    $usersHandler
+]);
+
+// Custom middleware
+class CustomMiddleware implements MiddlewareInterface
+{
+    public function process($request, $handler): ResponseInterface
+    {
+        // Pre-processing
+        $response = $handler->handle($request);
+        // Post-processing
+        return $response;
+    }
+}
+```
+
+### 📊 Event System
+
+**PSR-14 Compliant Event Dispatcher:**
+```php
+// Event registration
+$app->on('user.created', function(UserCreatedEvent $event) {
+    // Send welcome email
+    $emailService->sendWelcome($event->getUser());
+});
+
+// Event dispatch
+$app->dispatch(new UserCreatedEvent($user));
+
+// Hook system
+$app->hook('before.request', function($request) {
+    // Pre-request processing
+});
+
+$app->hook('after.response', function($response) {
+    // Post-response processing
+});
+```
