Maybe apt didn't, but apt-get certainly did; I tested this by
downloading several versions of apt and libapt-pkg6.0 from
snapshot.debian.org and installing them on a live system. The
difference I see in apt-get is between 2.3.2 and 2.3.3.

That test uses apt instead of apt-get, though. I never use apt myself,
so I didn't even think of finding out what it does.
