When I developed my
Ultra Visualizer (yay, took me several attempts but eventually I got it uploaded there), I found that AVS versions 2.81b and 2.81d don't display the SuperScope renderer which is required for my spectrums and phase display. This may have been a compatibility issue with Windows Vista+ (running Windows 10 here).
AVS version 2.82 works well. Never had any crashes with my preset, I guess the numerous reports were caused by different kinds of presets.
Now I got curious if any newer versions do exist. And this quickly started to confuse me. So there is apparently a version 2.83 in the
archive of the visbot network. Which identifies as version 2.2 in internal dialogs.

Also there are seemingly newer versions like: vis_chavs-2.9.dll / vis_chavsmod-2.9.dll / vis_chavsmod-2.9.1.dll ... which appear to be exact copies of that same 7-zip archive as the one I downloaded as version 2.83.

For some reason, I guess all the files the visbot archive sends me are the same, actually with vis_avs-2.2.dll inside. In case this is a fault of my webbrowser, and you are able to download the correct files, please share them!
I looked hard for any other sources but only found either dead links or github repos with sources only.
