UUID version 6 (UUIDv6)
A re-ordering of UUID version 1 so it is sortable as an opaque sequence of bytes. Easy to implement given an existing UUIDv1 implementation. See Section 5.1UUID version 7 (UUIDv7)
An entirely new time-based UUID bit layout sourced from the widely implemented and well known Unix Epoch timestamp source. See Section 5.2UUID version 8 (UUIDv8)
A free-form UUID format which has no explicit requirements except maintaining backward compatibility. See Section 5.3Max UUID
A specialized UUID which is the inverse of [RFC4122], Section 4.1.7 See Section 5.4
