Hi, If there is a way to dynamically find out the version of the structure returned by function in question, so that we can be sure that required fields are present, we may force 0x0600 version in source, just to get the structure definitions from official headers. Plus we also need to add support for older SDK versions, where the newer structure items were not yet available at all (for this there doesn't seem to exist well-known and documented way, so historically we check compiler version, assuming that it's always tied with a given PSDK version (which is theoretically wrong, but works in most installations)).
