There are occasions where a BIOS is built but, in final validation, this BIOS is found to have issues that must be addressed. In this case, the build subsequently produced will have a new build number and the previous number will never ship. Bottom line, whether you demand it or not, you won't be seeing build 76.
Firstly, you are here in a forum where customers share their knowledge about Intel products.
From time to time, a support staff member also is involved, but if you want to make an official complaint to Intel, you should do so via the official support channel.
BIOS versions are not linearly named.
Maybe you have noticed something similar with drivers?
Even with software products, version jumps are not always numbered with a number ascending by 1.
Or had Microsoft delivered Windows 9 to you?
I'm still waiting for an iPhone 2 and an iPhone 9, but since Apple has already reached the 11,
I'm afraid that the chances are rather bad, no matter how much I ask for it (and I would also be too embarrassed to demand this).
