TravelerOS is a light and stable Linux distribution based on Q4OS, which is based on Debian.
It's built for USB drives, not hard drives. TravelerOS runs KDE Plasma 5 (not 6). It's tailored as a portable Linux distribution intended for USB drives, although you can also boot it from a CD or an SD card.
TravelerOS is lightweight, using only 700 MB of RAM. It's also highly customizable, with KDE Plasma, which lets you customize the start menu, control panel, windows, icons, anything!
Since TravelerOS is portable, even if you boot the USB on a different computer, it still works where you left off.
It is intended for users who want to try/use Linux, without installing it on their hard drive, which means you can save applications, games, documents and other things without them being deleted upon reboot.
TravelerOS is also intended for users who need help with their hard drive or current operating system, such as repairing the bootloader, creating partitions on the disk, removing a partition, or erasing the entire disk.
Of course, as the name suggests, it is also for those who travel and need a computer in their pocket.

Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
