I wanted to try Gnome 40 and found that newest version of Fedora 32 Workstation has Gnome 40.
I downloaded the iso.
Checked sha256sum found ok.
In order to make persistent Live USB I downloaded
livecd-iso-to-disk script
made the script executable and kept it in the same folder as the iso
sudo ./livecd-iso-to-disk --overlay-size-mb 2048 Fedora-Workstation-Live-x86_64-34-1.2.iso /dev/sdb1
to make Live USB with 2 GB for persistence.
It took lot of time:
