We looked at the open source bootable USB tool Ventoy back in April 2020 when it first came out. The developer has been very active in the meantime; reason enough to take another look at the application to find out what has changed and improved.

Ventoy creates bootable USB devices using ISO images. That sounds an awful lot like what established programs such as Rufus do at first, but when you realize that it puts the ISO images on the drive and does not extract them, it becomes interesting.
