Quirky 8.1 “Xerus” is here to replace the old “April” series, and while it is indeed built using the binary DEBs of Ubuntu 16.04 LTS, it stays true to being a distro from the Puppy Linux family and not an Ubuntu clone. However, it lets users install packages from the official Ubuntu 16.04 LTS (Xenial Xerus) software repositories, a feature that was not available in the Quirky “April” releases. Another interesting change implemented in the Quirky 8.1 “Xerus” release is support for the Raspberry Pi 2 and Raspberry Pi 3 single-board computers (SBCs), along with the standard 64-bit (x86_64) and 32-bit (x86) builds for PCs. Being designed from the offset to be as lightweight as possible, Quirky 8.1 Linux is built around JWM (Joe’s Window Manager) and ROX-Filer graphical file manager, which is the standard for Puppy Linux.
