CKAN keeps track of dataset "revisions", you click on the "History" tab
on a dataset's page to see it, here's an example (CKAN 1.8):


In CKAN 2.0 datasets (and groups) have an "activity stream" tab instead
of the history tab, examples:

Logged-in users can click on the "follow" button on a dataset's page to
follow that dataset. In CKAN 2.0 you can also follow groups. Then when
you login to CKAN, you get an "activity stream" on your dashboard
showing activities from everything you're following. In CKAN 2.0, users
can also turn on email notifications and get an email when they have new
activities on their dashboard.
