[exim] clamAV and content scanning

never used exiscan or clamAV before so it's learning curve.
my question however is this:
latest clamAV is 0.83
exim spec for 4.50 suggests that "Clamd does not seem to unpack MIME"

later the spec indicates that demime ACL "is deprecated and kept only
backward compatibility".
question:
does clamAV 0.83 perhaps not require demime ACL any longer?

question:
if demime ACL is deprecated, is their a newer replacement for it?

TIA
