YouTube for Android gets a new Activity tab with two sub tabs: Shared and Notifications.

I just noticed a new Activity tab has appeared out of nowhere in the YouTube app for Android. The new tab has two 'sub tabs' under it: Shared and Notifications. The former got replaced by the new tab and got relegated to a sub tab. Notifications got promoted from users profile. In the end, it's two features of the YouTube app that are made easily accessible. No more fiddling around to find the channels you follow closely. I'm not sure though if this update is available worldwide. The YouTube app on my other Android device still does not show the Activity tab. Just check it out and with some luck, you may find it there.

Technically, this appears to be change on the server side, so I don't expect an update to appear in Google Play Store. Or maybe it will eventually and I'll keep you posted if it does.
