Latest 4.2 build number different for English than for other version

The name of latest 4.2 build is
- for English version 4.2.71.2
- for a version in some other language (it is an European language version) 4.2.71.5
Where does this discrepancy come from?

Why can't the latest 4.2 builds have the same number for versions of all languages?

Link to the 4.2.71.5 build placed on NOD32 EAV download page leads to 5.x download.
Why?


Similar question regarding the latest 5.x build.
For English language the version available is 5.0.93.0.
For some other language (it is an European language) the available version is 5.0.93.18.
What changes had been made between .93.0 and .93.18?
Where this discrepancy from?
When will be the latest build, the .18 one available also for English version?

 

The last digit is only for changes in localization. The software is the same.

 

Never. As it's been said, the latest number indicates changes in resources (strings). That said, English version 5.0.0.0 would be exactly same as 5.0.0.999.
