Edge

Players who own the Steam version of SimAirport are able to access edge builds via the Steam interface.

Edge is one of three branches of build versions for SimAirport, being released in a patch on 15 June 2017. It is the third official branch, after the default build and the experimental build; which were both released with the game's alpha.

The concept behind the edge branch is to allow "larger-scale changes [to have] their own branch for preliminary testing and feedback prior to moving them over to the Experimental branch"
