What is new in Ubuntu 18.10
Ubuntu 18.10 includes the new GNOME desktop 3.30 which comes with new features and performance improvements. The new Ubuntu 18.10 makes better use of the GPU RAM cache to cache shell components in RAM to decrease overall system load and improve frames per second on devices running the new version of the Linux distribution.
Users who make use of desktop zoom may notice that the operation performs a lot smoother. The smoothing of window previews takes the system's CPU and GPU utilization into account which should improve performance when the window preview feature is used in the operating system.
The encryption software VeraCrypt is supported officially by GNOME Disks which means that it does not need to be installed separately anymore to mount and create encrypted volumes.
