OPA187: Are those Orderable part numbers with .B suffix valid?

Tool/software:

I recently came across the datasheet for OPA187IDBVR (opa187.pdf) and noticed that there are Orderable Part numbers having suffix .B at the end. (e.g. OPA187IDBVR.B).

Are these part numbers considered a valid part number?

It looks like these are new changes with the ordering info.

Thanks.
