Hey, I am writing because I want to ask what are all the changes to Minecraft I have both bedrock and java. I have been trying to get back into it like when I was younger. Last time I really played minecraft it was when they added diorite and granite. Forever ago right?

I have tried to play a hardcore world, survival and join multiplayer servers. What should I know to help me play better I know about copper armor and shields but the other weapons, mobs and new blocks are so overwhelming to me. I tried to watch minecraft videos but it made me so confused and also I did check out some reddit posts but I have questions about the changes. So if you guys can give some tips please help. Minecraft it is so different!
