These features are only in Lightroom 6/Lightroom CC, and you would have to purchase Lightroom CC or Lightroom 6 (or use the 30-day free trial and then purchase it).
No. You need to upgrade to LR 6 or LR CC. Unfortunately Adobe's notice uses the word "update" instead of "upgrade".
Thank you. The pop up for the download says they are there, but I had misgivings when the tutorial showed LR6.
