Request #18246 has been accepted by diabonas [1]: Not sure whether this particular series of the NVIDIA drivers is still used by anybody (it doesn't seem like it since the package is orphaned and has been flagged since 2018), but the "-beta" suffix in the name is certainly not true any more and confusing for users looking for the latest drivers.
