u can collect that from official updates notes and of course, the best is from ingame... I mean to have an official account and play the game yourself... See how mechanics work and check if mangos have them, if not, make a patch for each of them..

currently mangos doesn't support 4.0.x branch... cataclysm brought a lot , and I really mean A LOT of changes in almost everything.. MaNGOS Devs will have to research for all of them and implement them one by one, and after they decide is playable inoff, and ppl can come with more fixes, they will switch... until than... hf with 3.3.5a:D
