# What's new in Chunker 26.1.2
- Updated for Paper/Folia 26.1.2
- Now requires Java 25 (moving forward this will not be backwards compatible with older server versions)
- Updated world and dimension detection for the new Minecraft world folder layout
- Commands now use names like `minecraft:overworld`, `minecraft:the_nether`, and `minecraft:the_end`
- Added optional `safety` mode for users who want a more careful pregeneration path
- Improved stop/restart handling during pregeneration
Most commands work the same, but world names are now based on the new dimension format.
Example:
`/pregen 16 5s minecraft:the_nether 2r`
Optional safety mode:
`/pregen 16 5s minecraft:the_nether 2r safety`
**Note**: A lot changed in this version behind the scenes, especially around world detection, Java 25, and the pregeneration safety path.
