In previous solutions recommended apps were favorited automatically. This feature has been removed for App Center 1.0. There's a new feature for mandatory apps, so you can assign certain apps to certain users based on their profile information. If this information changes, the set of mandatory apps will change accordingly.
If there's a macro (Apps or MyApps) integrated in a theme supplied by us before release of App Center 1.0, it might be necessary to upgrade your theme. Please contact us before upgrading to App Center 1.0. Also, you'll have to manually uninstall the previous solution (AppStore or Bookmarks plugin). Configured apps and users' favorites will still be there after the upgrade.
