Full changelog

Bug fixes

Fixed a bug where fresh Windows 11 25H2 (and other recent builds) failed MDM enrollment with error
80180006 because the device's discovery RequestVersion (e.g. "9.0") was rejected by an exact-match
allow-list. Fleet now accepts any MS-MDE2 discovery RequestVersion at or above the minimum supported
version ("4.0").
