When the new patch goes live, there will be a mission from Ram Tah to scan the ancient obelisks. It installs a decoder in your ship.
The mission should be available at all stations in the MEENE system. The results of successful scans were disabled in beta, so this is new territory.
I addition, the CTD issues in the Rift, Coflux and Hawking's gap should be resolved.
These are the documented new features in the mystery category. I would not be surprised by a few shadow updates as well. Our new friends may start behaving differently tonight.
