Well, there hasn't been an update for 5 and a half years, so don't count on it.
I stopped development on the scenario editor when the official SC map editor was released because i felt it was superior (especially the terrain tools). Instead i released the Marker Editor that allows to turn maps made with the official editor into FA maps. But i heard that many people had issues getting the official editor to run. Is this still the case?
I don't really intent to continue development on those tools after all those years, but it bugs me A LOT that they are so bugged and unstable. I still get bug reports and crash logs pretty much every day. This is not a quality standard i am used to nowadays and it hurts my pride.
The problem is that i changed my primary programming language in the meantime and my graphics engine and tools and stuff like that evolved a lot in those 5+ years. There is no way i'm going back to the old programming language, engine and tools to update the program, thus the only way to release an update would be to port the programs to the new system. This, however, is a hell of a lot of work.
I, nevertheless, actually ported the Marker Editor just recently. It took me like an entire day so far, but seems to work now. I'd have to test is a lot before releasing it, though, to make sure that porting it didn't create some error that corrupts maps. The mere port should already boost stability A LOT because my updated engine and tools are far more advanced than they were 5 years ago. I startet working on a port for the Scenario Editor too, but it is far more complex and thus porting it will take much more work.
But i can't tell when, if ever, there will be a release of an updated version. Also don't get too excited for new features, because it'll probably just be a stability update without new functionality.
