This new feature allows you to check the status of certain entities at runtime. Make sure that the mouse pointer is visible (right click to show it if you need to) and then press Shift + F11. The game will freeze and you can click on any entity to display its status. Press Shift + F11 again to resume the game.

24 bit skins

MED supports 24 bit TGA skins for models and terrain; they will be rendered in 24 bit color depth, without alpha transparency (if the alpha channel isn't used).
 

Conditional breakpoint

Now you can activate the debugger as soon as a given condition becomes true. Place the lines of code below at the end of your main function:

while (player == null) {wait (1);}
player._armor = 10;
breakpoint_on(player._armor < 10);

and the debugger will pop up as soon as player's armor goes below 10.
