While we all like courses to be updated I must say I still find value in courses made with 2.79 blender version, there are some gems hidden in older courses too and I still go back to look for some things sometimes, being said that updates are always welcome but do not discard value in older courses, I understand for beginners it is confusing but as one gets to know how to use blender also gets to know how to associate concepts and what is where in newer versions, it is sad to see really good older courses gone just cause they are outdated and hehe new courses are always really nice to have
