Win10 preview version 10075 updated what content

Win10 preview version 10074 is the latest public test version released by Microsoft in Build 2015. In this version, the frosted glass effect similar to Win7 Aero began to rejoin. However, Microsoft is still conducting a trial on this special effect. If the response is good, it will consider a greater degree of return. It can be said that the speed of Microsoft's update of Windows 10 Preview is accelerating. This is because the official release date is approaching, and more new content needs to be previewed by members in advance & "test". When querying the progress of the Win10 version, you can find that the Build 10075 version is marked as Public Release, which means that the version will be published publicly.

Compile date, this 10075 to be released is formed on April 28th in the US, which is the day before the opening of Build 2015. However, Microsoft did not take it to the venue for demonstration, nor did it release it immediately. From the version number, this version is only more than the current public release of 10074 "big one", if the version is "the next player" is a more special choice. Because according to past habits, the publicly released version number is very hopping, and the situation of the "number" is still seen for the first time.
I don't know if this is the case, the gap between this version and the latest version is very small. If this is the case, then this is not very obvious for the majority of users. If not, then what is the reason why the version numbers are so small? If Microsoft does not change its mind, we should know the answer when the version is released.
