E18 is the next release out of the Enlightenment project while the really interesting Wayland changes will come with E19. With E19, Enlightenment can act as its own Wayland compositor. Regardless, E18 is still decent in its support of Wayland.
With this Enlightenment Git revision by Samsung's Chris Michael today, the E18 Wayland client application support has been updated against recent Wayland changes.
Update: There's also Wayland EFL changes today too.
