For Data Visualization Desktop (AKA DVD), 18.104.22.168.0 download link here.
The latest version of OBIEE 12c is now available. 22.214.171.124 is available by either inplace upgrade or a fresh new install. I always prefer fresh install and migrating. You can download this at Oracle and notice the installer updated on June 21, 2016. A kind reminder to upgrade your JDK and client tools as well!
