[elie29]

new Config([
        'dependencies' => [
            'services'   => [],
            'invokables' => [],
            'autowires'  => [], // A new key added to support PHP-DI autowire technique
            'factories'  => [],
            'aliases'    => [],
            'delegators' => [],
        ],
        // ... other configuration

        // Enable compilation
        Config::DI_CACHE_PATH => __DIR__, // Folder path

       // Enable cache
        Config::ENABLE_CACHE_DEFINITION => false, // boolean, true if APCu is activated
])
