我的世界Java版 21w39a 发布 加入了洞穴与山崖第二部分的进度

Time for an advanced snapshot! In this snapshot, you can also open worlds from previous versions again – with one big warning! The blending technology we intend to introduce for Caves & Cliffs: Part II is not yet available. If you open an old world in this snapshot it will be upgraded with air under the current bottom of the world and visible chunk borders to new areas.

We highly recommend backing up your world before loading it in this snapshot.
是时候发布新快照了！在本周的快照中，你可以打开之前版本的世界了——但是会有一个巨大的警告提示！我们希望为洞穴与山崖第二部分引入的混合技术暂时还不可用。如果你在本快照启动一个旧的存档，那么它会自动升级，原来的底部会用空气填充，而且和新的区域之间会有明显的边界。

我们非常建议你在打开存档前先进行备份

Effects
状态效果
