You will have to go where no man has ever gone before. Literally. If you have ever loaded a chunk, it will not have new content. You would have to go far enough to load new chunks.
That means you have to go walk outside of the area you have already explored. It doesnt mean that the first thing you find will be a swamp with a witch, but it is the only way for new features to get generated
It would take 80-90 hours to just reach the end of the world, let alone explore the entire thing. You must have more to explore! Also wither skellies should spawn, that has nothing to do with the world.
is it possible to find any of the new content on the server? we found carrots and potatoes on zombies but
we havent found any witches yet, no bats, no wither skeletons, no heads, none of that

but i dont know about witches yet
also the world has a border and the whole area inside it was pregenerated
I think witches only spawn near witch huts, which are a generated structure.
