Where did the enderdragon go in the new snapshot?

So I go to the end in the new snapshot to check out something to do with the ender dragon, but when I get to the end, the enderdragon isn't there and the bedrock thingy in the center is missing. All the obsidian pillars and the end crystals still remain. The endermen act normal. But when I try to use the technique to respawn the ender dragon, a portal to go home appears. Not sure what magic those witches are using now.
