Version ID Question

I was noting that my version of eM Client is: 10.1.4588 (f11e2ab). What does the “(f11e2ab)” mean?

Where do you see that (f11e2ab) ?

When I go to Help>About, the eM Client message has “Version: 10.1.4588 (f11e2ab)
Copyright: © 2006-2024 eM Client s.r.o.”

When I go to Help>About, the eM Client message has “Version: 10.1.4588 (f11e2ab)

Probably just a eg: auto generated number when the build version is created for Windows.

The Mac version of eM Client also has numbers in brackets after the version number. 10.1.4828 (9843340).
