Recently, one of the creators of Minecraft, known as Ulraf, had a conversation with AdirTV. He decided to share his vision for a potential rework of the End dimension.
The developer clarified that these are his personal thoughts, and not Mojang's official plans for future updates.
If Ulraf were to update the "End" dimension, he would introduce several biomes into it. In addition, he would add additional blocks and mobs, and improve the battle system with the Ender Dragon.
The developer also drew attention to community modifications that make changes to the "End". He noted that his vision involves a minimalist design based on the concept of "Wasteland."
