The latest Arnis update brings full Minecraft Bedrock Edition support. This was requested a lot by users and is now released with the Bedrock Expansion Update. You can now also view a live preview of your generated map directly in the GUI. World generation is noticeably faster than before, and numerous behind-the-scenes improvements greatly enhance performance and stability.
