Note that the number at the 3 position in the version number (e.g. 188.8.131.52) just indicates a sub-version provided in different regions of the World. The last basic version is 184.108.40.206.
However, a version number with .32 at the 3 position (i.e. 220.127.116.11) would indicate that this is the so-called business version without Facebook integration, while 18.104.22.168 would be a special version provided for users migrating to Skype form Messenger. Installer with this version number removes Messenger from the computer on the installation of Skype.
You can also check the version number of a downloaded installer by right clicking on the file and selecting Properties -> Details.
