If the add-ons are part of the community add-ons, and you have the Add-On Updater add-on installed, when compatible versions become available you will be notified and you go through the standard process to update.

If they are third-party add-ons, then you have to take care of it yourself.  This means, of course, for each third-party add-on individually.
