In short, instead of downloading an ISO image (a format originally designed for CDs), you now download Tails as a USB image: an image of the data as it needs to be written to the USB stick.
Tails 3.12 Big News completely changed installation methods
- For macOS, the new method is much simpler as it uses a graphical tool (Etcher) instead of the command line.
- For Windows, the new method is much faster as it doesn't require 2 USB sticks and an intermediary Tails anymore. The resulting USB stick also works better on newer computers with UEFI.
- For Debian and Ubuntu, the new method uses a native application (GNOME Disks) and you don't have to install Tails Installer anymore.
- For other Linux distributions, the new method is faster as it doesn't require 2 USB sticks and an intermediary Tails anymore.
We are still providing ISO images for people using DVDs or virtual machines.
The methods for upgrading Tails remain the same.
