The major addition in this update is the adoption of Minedown, in many string fields in the configuration (although not all). You can read more about it here:
https://github.com/Phoenix616/MineDown, this allows you to use custom colours that aren't supported in the traditional legacy colour code system. You can see an example of it being used within the Dragon hero when you see the cooldown message of it throwing a fireball.
I have also made the config more standardised, there have been many random variations with how cooldowns are handled between skills or how you select an item, these have all been fixed. I have also removed the strange "%s" from strings and replaced it with a placeholder more accurate to its description, for example, %currentcooldown% represents how much longer a player must wait to use an ability again.
If you are updating from an earlier version, I recommend you to backup your Superheroes2 and regenerate it and then put your changes back into place afterwards so you get the new Dragon hero as well as avoid having to troubleshoot the changes in names within the config.
