NTLite releases every 1-3 weeks, depending on what new features or bug fixes are ready.
It doesn't track the Dev or Beta schedule, so not every build is recognized by NTLite. Unknown builds are limited to basic features like Settings, Unattended but no changes to Updates, Components or Features (those need to know the Windows version).
Most users download Insider builds, and install a clean system. It's usually faster this way, then trying to read the latest news on applying Insider updates to a current system.
