Could you please restore the Fedora 32 behaviour? Someone must have read
the bash manual a little too precise, because now the statement only
returns true when a 'touch -a test' is given and not when a 'touch -am
test' is given.

As I understand it, -N stands for NEW and therefore should return a true
when either a 'touch -a test' or a 'touch -am test' is given.

Why do you think `touch -am', which sets the atime and mtime to the same
value, should make -N true?

If test -N is a strict test that mtime > atime, it is working correctly
and you have managed to defeat it by setting atime == mtimne.
