I heard and I believe it said that it allows exporting option to export to native apps. I got over excited and still am. :D
but after the update I noticed many things changed, like there's a 'configuration' thing on the top menu bar, and of course, the export button is now clickable!!
when I press set the target to windows and press export, select where to save the game, when it complies it shows an error messages saying,
Error in script "C:\Users\Despicable\Desktop\Despicable\GM Projects\sample_game.gmx\Configs\Default\windows\RunnerInstaller.nsi" on line 67 -- aborting creation process
if I just press the green debug button to test it, it just complies normally and the game works perfectly.
also when I set the target to iOS or to Mac, it shows

also I noticed this new menu in the top menubar -

I don't understand what this is either.
I tried to look it up on help file if there already existed an instruction for this, also GM wiki. I believe there still isn't a topic about it yet here(or at least when I checked it a few min. ago). So I just posted this. Thanks!
