Though I hesitate to speculate openly about roadmap concerns, I can say that we plan on validating/supporting Oracle 12 in a future release this year. The difficulty is that we must bridge support for both 12 and older but still recent versions to support existing customers. It is unlikely that we will patch already released versions to include Oracle 12 support, so upgrades to the version that offers initial support for it will likely be required. I would encourage you to check the version history section of released versions' manuals as there will be notes about the updated supported window of Oracle versions there when those changes occur.
