What is the current status of the UA Revised Ranger?

14 months ago, an Unearthed Arcana supplement was published that discussed how the ranger described in the Player’s Handbook was under powered. These rules reimagined the ranger’s abilities, and suggested that an official version would be released later.

Finally, we come to implementation. If this iteration of the ranger, or a future revision of it, grades high enough, our plan is to present it as a revised ranger in a future D&D sourcebook.

Does that Sourcebook exist yet? If not, have the devs given an update or told us their intentions?
