Where did the FB API Key go?

Setting up a new site with the ultimate fb plugin, which required a new fb app…. and is it just me or did the API Key field disappear on FB? The plugin needs: App ID, API Key, and Secret… and I've seen all three before. but with this new one app (and even if I go back through my other apps…:wink: I'm only seeing App ID and Secret. Did FB change something? Will the plugin still work? Maybe I just need more sleep and am just missing something completely silly. But where'd the API Key value go?
