You should take that with some context.

If you build new software against the newer MiNTlib then it can take
advantage of new system calls which are not present in older kernels.
Depending on how the software is written it may not fail gracefully if a
system call fails.

Now, this is really with new unix style software, but for Atari software
compiled against the mintlib it's unlikely to take advantage of these
new system calls so should work just as well with old kernels as new
kernels.
