That feature is now called `ess-insert-assign`, and you need to bind it to the `_` key yourself. From the example in the manual:

  (define-key ess-r-mode-map "_" #'ess-insert-assign)
  (define-key inferior-ess-r-mode-map "_" #'ess-insert-assign)

I think this is only documented on the *New Features* page of the manual now, which I never think to check when I'm looking for things.
