The first "season" of expansions for "Elite Dangerous", named "Horizons", was announced on 5 August 2015 at Gamescom, entered beta on 30 November 2015 and was released on 15 December 2015 for PC, followed by a 3 June 2016 release for Xbox One. Frontier Developments currently has no plans to release the expansion for Mac OS X unless Apple provides support for compute shaders, which Frontier believes are required to render planet surfaces and other objects. "Elite Dangerous: Horizons" is a separately priced product. Original customers who also purchased "Horizons" received exclusive access to the Cobra Mk. IV ship.
