I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

Expected result (rendered using siunitx 2.7u):

[josephwright]

This is a documented change from v2 to v3: https://github.com/josephwright/siunitx/compare/v2.8e...v3.0.0

[UlyssesZh]

Is there a v2 to v3 migration guide?

[josephwright]

The changes are listed in the manual: very little is needed in the vast majority of cases, but you have one of the pieces of input that on revisiting I decided was a poor design choice.
