A list of Skype version partner IDs and what they mean: If you don't know what a partner ID is, it's the number at the third part of the version string: Skype x.x.x (<- this).xxx (example: 6.18.99.106) Skype used to partner with multiple companies, most common being internet portals. In addition to Skype partnering with these companies, they made their own versions whose differences ranged from a single digit being changed in the version string, to a new UI with the partner getting their own ads embedded in the app, their logo in the about screen etc. A good example of this is e-kolay, which had their logo always visible in the background of the main window and they even had their own "e-kolay" tab. This was in the Skype 3 days where Skype still had a tabbed interface. e-kolay was a Turkish internet portal. 0 - most common (example: 7.4.0.102): - Standard official Skype EXE/MSI installer. 1 (example: 2.0.1.81): - Skype-PChome partner EXE-only installer. 2 (example: 2.5.2.151): - Skype-Packard Bell EXE-only installer. 4 (example: 3.2.4.117): - Skype-TOM partner EXE-only installer.
