Packed with all the latest software updates and security patches from the upstream Debian GNU/Linux 9 “Stretch” repositories, Parrot Security OS 3.9 entered Beta stage of development, and the team put a lot of effort to prepare a bunch of ISO images that you can download and install on your personal computer if you want to help them hunt bugs or just report if everything runs smoothly. If you want to test the Parrot Security OS 3.9 Beta release, all you have to do is to prepare a USB flash stick of at least 4GB in size, download any of the Parrot Security OS editions you’re interested in, such as Full, Lite, Air, or CD, for either 64-bit or 32-bit architectures, write the ISO image on the flash drive and boot it from a USB port on your personal computer.
