Last month we should have seen the release of Solus 4, the new version of this popular operating system within the Gnu / Linux distributions. However, this new version has not yet arrived and unfortunately it will take time to arrive, although it will arrive.
Solus developers They are still working on the new version and they are also still implementing new features such as the new Wayland graphical server. Wayland, as in other distributions, will be in Solus 4, but it will not be the default graphical server of the distribution.
The union of GTK + libraries (which are used by Gnome and Budgie Desktop) plus Wayland is still not as good as it seems and therefore the developers of Solus have decided not to use it as the default graphical server although if it will be so that any user can install it and use it in Solus if they wish.
Budgie 10.4 will be the new version of your popular desktop, but it will not be the expected and novel Budgie 11, a version that many users expect. The kernel as well as other popular libraries and packages will be in their maximum version, like this Solus 4 will have the new kernel 4.15 although it is being developed on kernel 4.9.1.
There will be some absences such as the snapd package manager that allows the installation and use of snap packages. These packages intend to reach Solus and they will arrive, although it will not be in Solus 4 when they do, but it will be later. The developers want to implement this package manager but the work required to do this is still a lot and that makes it impossible for Solus 4 to have it or to launch it this year. The launch of Solus 4 remains unspecified but at no time has it been denied in 2018 as the release date, that is, in a few weeks we will have this new version of Solus with its news and as popular as it is currently.
