Security related upgrades

[Watson Ladd]

Dear people in the know,
Let's say a package gets updated because of a security issue. Will
macports prompt to upgrade the dependents so they do not
rely on broken packages, or is this something that
the end-user always needs to be aware of?
Sincerely,
Watson Ladd
