final ENIGMA version
I doubt there ever be one, as we don't version ENIGMA at all (as far as I know).
except that it becomes increasingly harder to attract the GM people now that they've constantly been improving it ever since that guy got hired
Its more due to slow progress of ENIGMA than to anything else. People want functionality, and that is something no one here is ready to implement. Users don't care that you can draw 10x more sprites than GM, if that is all it can do. I am the only semi-active person that actually tries to implement these GM features. I am trying to add more surface functions right now (like surface_save and sprite_create_from_surface among others).
