Apple has updated its iTunes U app to bring it in line with the recent changes to iTunes, migrating the collections features to the Podcasts app just like they were moved to the podcasts area within iTunes.
Other than that, the app functions mostly the same as before, allowing users to view iTunes U courses and offering “performance improvements for accounts with a large number of courses.” Links to collections from within the iTunes U app will now open directly in the Podcasts app.
