Solus follows a rolling release model where the user installs the operating system once and receives updates forever. The latest update pack brings the recently released Linux 5.5 kernel series, which introduces full Raspberry Pi 4 support, cross device offloaded copy for NFS clients, Btrfs RAID1 with 3- and 4- copies, and much more. This means better hardware support for your Solus installations. The ALSA (Advanced Linux Sound Architecture) sound system has been updated as well with the latest Solus update pack, greatly improving audio by improved support for devices like Broadwell Audio DSPs, Gigabyte Motherboards with dual HD-audio codecs, Dell WD15 Dock USB-audio, Intel Broxton SoCs, Intel Skylake I2S, and Lenovo Ideapad Miix 320.
