Searching for mods (looking for mods for Tribes of the East).

Okay, there's a lot of information – I need to process it. Can you tell me what the difference is between version 3.0 and 3.1? Honestly, I'm not sure; I think I've only used version 3.1. Next (I'm answering everyone at once, guys, I won't personalize it), what exactly is the work on the EXE about? What kind of crashes are we talking about? Does this relate to some global mods? I understand that people don't have a lot of time, but modding, as one person said, is an unrewarding task. It takes time and effort, but there's usually no return or gratitude – so, essentially, it's at your own risk. Regarding the Factions – this is very important and interesting. Remember Heroes 5; it was simple, and then they suddenly added dwarves and orcs. How many people did this make return to the game, how many new emotions and impressions, and how much interest did it generate? And most importantly, if we can figure out how to add them, the process, so to speak, the recipe, then it only needs to be done once, and then you can just follow the pattern and do it again. P.S. I understand that besides the recipe, there are models, animations, buildings, textures, balance, abilities, and skills, etc. But that's already Creation, and it can be done not by one person, but by a team.
