This is indeed true. If you are particularly worried about a package you

You can also use the fabulous facility of snapshot.debian.net to get
specific resources from a particular time in the past. To assist you in
doing this you may wish to run a
dpkg -l > installed_packages_$(date "+%d%m%Y").txt or something
so that you know what version of what you had installed previously.
