What's new

0.3.0-beta Latest

9 November 2026

New

• Schematic to world. Pick "World download" to get your build placed in an empty world, for Java 1.16.5 to 26.3 or Bedrock.
• Entities and items come along. Armor stands (with armour, poses and names), item frames, paintings, and the items inside chests, shulker boxes and other containers are carried over when you upgrade.
• Forgot password. Reset your password from the sign-in page with a link sent to your email.

Improved

• Upgrading from one modern version to a newer one now updates heads, signs, items and armor stands to the newer format too.
• Stair corners are worked out the same way Minecraft does, so they match what the build looked like in its original version.
• Doors keep their hinge side and stay together as one door.
• Flower pots from 1.7 to 1.12 keep their plant.
• Heads on the floor keep the direction they were facing, and custom head skins are carried over.

New

• Convert to up to 10 versions at once. Pick several versions and get every file, plus one ZIP with all of them.

Improved
