I don't know what you may have observed before.
If you install an app with blackberry app world, app world will eventually alert you that an upgrade is available.
Some apps have a manual 'check for update' feature, though I can't recall off hand having an app automatically notify of an upgrade.
And of course you might receive a message if you've registered with the developer or vendor.
