 - Important Changes:
   * The enum value ResourceTypeUnknown has changed value because there was
     a mismatch between 5.6 and 5.7+ definitions. In general any unknown
     ResourceType value should be handled as unknown for forward
     compatibility, because more types are and can be added in later
     Qt versions.
