TL2 versions confusion - 188.8.131.52a vs 184.108.40.206
I recently bought Torchlight 2 from GOG.com. Great game, but I'm confused about version numbers. I was browsing the net for TL2 related content and I saw someone mentioning TL2 version 220.127.116.11. That was strange to me, because GOG is telling me the latest version is 18.104.22.168a.
So my questions are:
1. What is the latest version of Torchlight 2 at the moment (2018.04.23) ?
2. What is the difference between versions 22.214.171.124a and 126.96.36.199 ?
