I thought I'd be able to find some explanation posted here, but haven't found anything.
I had often used the Linux scripts for downloading updates, since I don't run Windows on my system (but fix Windows systems for friends/family). I see in the 7.4.2 version you dropped Linux script support. What broke that made the Linux scripts no longer maintainable (I'm presuming Microsoft broke something, but it woyuld be helpful to explain just what that was here).
