This release incorporates functionality up to the 5.3 kernel, and adds a number of bug fixes, and improvements. Highlights include a new command to reconfigure dax devices to different modes (devdax - default, and system-ram - to hotplug the dax device as system memory), improvements to ndctl-{read,write,init}-labels allowing smaller sized reads/writes, usability fixes to ndctl-monitor, and ndctl-create-namespace, and a fix to ndctl-check-namespace allowing it to be used on systems with different page sizes.
