Answer 1

The What's New in Qt 5.5 says:

Added Q_ENUM to replace Q_ENUMS, which allows to get a QMetaEnum at compile time using QMetaEnum::fromType. Such enums are now automatically registered as metatypes, and can be converted to strings within QVariant, or printed as string by qDebug().

Answer 2

Since Qt 5.5 Q_ENUMS is deprecated, replaced with the better Q_ENUM.

There is an example showing its use in the Qt documentation:

class MyClass : public QObject
{
    Q_OBJECT
    Q_PROPERTY(Priority priority READ priority WRITE setPriority NOTIFY priorityChanged)

public:
    MyClass(QObject *parent = 0);
    ~MyClass();

    enum Priority { High, Low, VeryHigh, VeryLow };
    Q_ENUM(Priority)

    void setPriority(Priority priority)
    {
        m_priority = priority;
        emit priorityChanged(priority);
    }

    Priority priority() const
    { 
        return m_priority; 
    }

signals:
    void priorityChanged(Priority);

private:
    Priority m_priority;
};
