The first post is telling you which modules have been updated only. There are no links. In order to see the LOS in action in those modules you will need, as LE points out, to own them; that is you will have needed to have bought the modules from the store or from Steam. You access them in the usual way via Library > modules > Load. If you haven't bought any of the modules then you won't be able to see any of the LOS.
