Create a libfoo1 package, have it include the necessary library files (and perhaps a -devel subpackage if you wish for things to compile against it) and update the base libfoo package to the new version.
We do this all the time. Some packages utilize an older naming scheme involving a "compat-" prefix but that shouldn't be used these days.
We also strive to maintain ABI stability on stable releases, so in theory this happens during major upgrades when compat packages are not involved.
