advantage of this model is that once the operating system is installed, updates can be run continuously, rather than large upgrades. To maintain the stability of the system, Solus's access requirements for the latest packages and beta software are very demanding.Solus supports multiple editors and Ides, such as Atom, idea, Gnome builder, and Git GUI, Gitkraken. The Solus Project website also claims that the operating system supports some programming languages such as go, rust, and PHP.Solus's (
