You can turn this back on in Sound preferences
Wow, thank you.

I didn't know I was missing the blips until previous poster said he was missing them, but now I'm glad mine are back also! (Although the old mavs and "cat" releases blip sound was nicer to my ears. Not sure why it needed changing... *shrug* You get some, you give some I suppose!)
Yose is great, IMO. I'm really liking the new look, it's smooth and super professional looking - to my eyes. Understandable if some detest it - nobody likes
everything.
One thing they could have fixed though is the clumsy way you pick networks. Right now, if your regular internet connection goes down and you connect your iphone as backup, you need to either disable the non-working interface (and if you disable wifi, things like Maps and maybe others too will whine at you), or you need to manually re-arrange the connections list by means of a drop-down menu, opening up a new window and dragging the connections there. You can't even drag the connections right in the main window, you need a second window to do that...
Then you need to hit the "apply" button to actually make your changes stick. And you need to change the list order back when your main internet connection goes up again or you'll unwittingly suck your iphone's data cap dry by needless surfing and downloading stuff via cellular data.
Why can't it do this automatically? Or at least pop up a window asking if I want to use Working Alternative Connection X (such as my iPhone)? Maybe I'm missing something, but I don't see something like this seamlessly working, and I'm on my fourth consecutive OSX release now.
To be fair, windows handles this just as sh** as well, not that it's any sort of excuse for Apple to drop the ball. Internet access is becoming more and more important, and with the addition of iCloud Drive and so on, Apple's bringing us one step closer to constant, ubiqutous, persistent online presence with not just communications, but our data as well...
