As I read it, the only thing that could change is that KRandomSequence
and QRandomGenerator will produce different outputs for the same seed
value because the underlying PRNG may be different. So that might
introduce a backwards incompatible change if you rely on the output of
the sequence remaining stable between two versions of KPat. However,
seeding it with a fixed value and then consuming the sequence should
remain fully reproducible between two instances of the *same* KPat
version.
