 * Bits 31-24 make the most significant part of the version number. This number starts from 1 i.e. the second version of the API will be 0x02xxxxxx. This number changes only, if the API itself changes so much that it is not compatible anymore with older releases.
 * Bits 23-16 API minor version number. For example API version 2.1 would be 0x0201xxxx.
 * Bits 15-8 are the number of the year when release is done. The 0 is year 2000, 1 is year 2001 and so on
 * Bits 7- are the week number when release is done. First full week of the year is 1
