CachyOS was founded a year ago. After almost one year of development, we are really proud to announce our first Stable Release of GUI Installer. We spent a lot of time investigating repo management, kernel development, infrastructure, theming, … and finally put them all into the CachyOS GUI Installer. All the features we worked on and implemented into the Installer are just trying to offer users a completely customizable experience.

The most exciting changes are that we use now for the online install pacstrap which provide then a complete clear installed environment and we do support a complete native support for the zfs filesystem

Since Discord restrict the length of the messages the full announcement can be found here:
