Among the biggest improvements implemented in Rockstor 3.8-15, we can mention multiple enhancements to the web-based user interface, in particular the dashboard, major refactoring of the backend disk management, including the design, as well as numerous other under-the-hood improvements, bug fixes, and updated components. A RAID56 warning was implemented, long nutanix device names are now supported, Docker journald logging support is now integrated, test e-mail notification has been improved, as well as the NVM Express (NVMe) compatibility for the system disk, and a Samba regression has been addressed.
