The URL scheme is the convention I follow, but I also include the version# in the file name.
I did put the executable inside of a ZIP archive, along with a text database and a few video pixel shaders. One change I made recently was moving from .7z to .zip since some users don't have 7-zip installed, but I presume Google is smart enough to scan inside 7-zip archives even if Windows isn't (out of the box at least.)
I've been providing these releases for fourteen years now. I have no idea what suddenly changed other than it took about two years to release a new version due to a lot of massive changes.
I appreciate the reply all the same, thank you for taking the time.
