Different avast free build on laptop vs desktop

[predatorz]

Hi,

2 Laptop and 1 Desktop - Win10
All laptops and desktop i installed with Avast Free with same custom installation options (File, Behavior, Web, Mail shields, Rescue Disk, Wi-Fi Inspector)
But I notice that UI version is the same at 1.0.460 but the build version is different as below
Laptops - 20.1.2397 - build 20.1.5069.561
Desktop - 20.1.2397 - build 20.1.5069.559
Only difference that i can think of is that desktop is upgraded from windows 7 to 10 and laptop are on clean win10 installs
Everything is working fine.

I would like to know if cause of different build is as above and the differences between different builds for curiosity. 
Thanks.

the desktop has been rebooted many times before.

have also tried to check for updates via Avast UI but no updates that why i am curious to know why the different build between my desktop and laptop.

Weird, receive another update on my laptops and desktop.

Currently at version 20.1.2397 (build 20.1.5069.562)

Whilst over a year late, the original poster wasn't asking that question. 

Rather if there is are any differences between Avast for a desktop and a laptop.  Which essentially there aren't, there may well be if they are on different Operating Systems.
