This is very much old "standard" vs new standard in terms of naming.
For those of us that have been around long enough, Mega/Kilo/etc have
always meant 1024 when addressing computational storage, as per for
instance ANSI/IEEE Std 1084-1986.  However, as people know this did
become (or has always been) used ambiguously and so these terms were
apparently deprecated in favour of MiB, KiB etc by the IEC starting at
around 1996 and with formal adoption 1999 with IEC 60027-2 Amendment 2
(and expanded adoption in ISO/IEC IEC 80000-13:2008)
