They are the tasks apps. We excluded these apps from the core because it would be easier for us to release smaller updates on the apps without pushing out a new release for the core.
It would be really helpful to include short information on the in-site notices for upgrade that you also need to update apps. You guys should be informing us of what should be done to ensure a smooth upgrade. What other apps need to be updated for Easysocial 2.1 to work properly? Do you guys have a list we can work through?
If you are talking about the Applications->Discover or Application Store, I received a notification to update one app which was not the group tasks app, and nothing else.
