Just checked Tim’s latest post and guess what, Oracle database 12c’s latest release, 220.127.116.11 is available now for download. It is available as an OTN download as well as from E-Delivery. Seems like that there is no documentation update available yet as the New Features guide still doesn’t have 18.104.22.168 included in it. But I am sure that it’s coming soon!
So grab your copy now and happy downloads :=).
Update: The documentation is updated and if you are looking for the new features introduced in 12102, check the following link.
