At that time we did not have cpecialist, so procedure was rather complicated. First 1.0.7.5 was installed on the clear Arc, then UAP.Wait, you guys don't have a changelog?! Sorry bro but as a fellow modder, I have to be frank here and say the truth.
Namely, no changelogs when modding = amateur hour. No offense. I can barely remind shit, when I mod I have task-lists and changelogs, otherwise I can't remember shit about what I did. Maybe you guys have better memory.
*.dlg and scripts were compared. Best options were chosen.
For the current versions we have bugfix list.
