They seem to be doing UI changes to the website.
Currently the non-ARM version of the ISO is in the main page (https://endeavouros.com/) just scroll down and you'll find the mirror list of the most recent ISO by country. Dunno why it's there NGL shrug
Didn't ask for it...but at the same time, actually existing beats not existing IMO. And since I (and by extension, you and anyone else) exist in an uncaring universe, I am free to live life as I please--within reason--so all things considered it's...actually not bad at all. Yeah there's sucky parts to it, but most things that are worth it have bumps in the road.
