Known limitations
Upgrading from 0.5.0 then newer 0.5.x releases:
The current Playbook is designed to preserve user files, applications, and most Atlas folder configuration during supported 0.5.x upgrades.
Older versions:
AtlasOS v0.4.1 and earlier may need a fresh install or a specific archived upgrade path. Do not assume AME Beta will show an upgrade option unless the Playbook supports your installed version.
