If you installed well-known distros like OpenMandriva, KDE Neon, Sabayon, KaOS, Siduction, Netrunner, Apricity OS, Chakra GNU/Linux, GeckoLinux, Pisi Linux, Tanglu Linux, or Manjaro before, chances are you already interacted with the Calamares installer. The latest version of the installer is Calamares 3.1.1, a release that fixed a password weakness issue, and to which all the above GNU/Linux distributions should upgrade. But it looks like Calamares is getting ready for the next-generation Wayland display server, which offers improved security over X11.
