The MX guys have just released a new beta ISO: https://mxlinux.org/blog/mx-21-beta-1-now-available-for-testing-purposes/
New things/changes:
Now there's a full-screen Plymouth theme. It's oddly similar to the old default background to Artix Plasma (like it looked last December). Coincidence? Nah, just a stock photo.
Wallpaper has too many things on it; they do plan on changing this. Just thought I might mention it; since it kind of is the main difference.
Wi-fi still does not work, neither in the live desktop nor in the freshly-installed environment.
verdict: still stands
