This version has the same software selection as the standard Newt OS Studio builds, but uses the Tumbleweed repositories. This makes this appliance a rolling release, eliminating the need for yearly upgrades, as system updates are installed progressively along with application updates.
In addition to the switch to Tumbleweed repositories, the Loki desktop in this appliance uses Mate session and several Mate applications, replacing LXsession. While this slightly increases memory usage, it will be beneficial in regards to future-proofing, as LXsession and related applications are largely unmaintained, as development has shifted to LXQt.
To reiterate, this is an experimental release. My machine running this system has not had any issues, but I would like to wait until after the next big round of updates for Tumbleweed to ensure that nothing breaks as a result of updating.
