我的世界Minecraft Java版17w47a发布。每周快照是Minecraft的测试机制，主要用于下一个正式版的特性预览。然而，每周快照主要用于新特性展示，通常存在大量漏洞。因此对于普通玩家建议仅做测试尝鲜用。使用测试版打开存档前请务必备份。适用于正式版的Mod不兼容快照，且大多数Mod都不对每周快照提供支持。Minecraft 1.13 仍未发布，17w47a为其第6个预览版。
Minecraft 快照 17w47a
Java版 1.13 的快照
This weeks snapshot brings us the long awaited "flattening", which will absolutely break everything. Sorry. Make backups.

Added the ability for us to add new blocks in the future again! Hurrah!
加入了能让我们在未来加入新方块的功能。爽到!
There's new blocks, but I want to just emphasize thateverything will probably be brokenand to go make backups instead of focusing on new stuff
这个版本有新方块了，但我要强调，所有东西都可能坏掉，所以先备份，不要急着看新东西。
一个警告
This snapshot should be considered "extremely, extremely experimental". From a scale of 1-10 where 1 is experimental and 10 is stable, this is a very firm negative 5.
这个快照可以说是“非常，非常实验性”的。如果1到10里面1是实验性的而10是稳定的话，这个版本就肯定是-5了
Back up your worlds before trying them in this snapshot. Don't expect worlds played in this snapshot to work in future snapshots.
在玩快照之前备份。不要指望在这个版本玩过的世界到以后的版本还能玩。
不过认真地说
This snapshot represents a few years worth of internal refactoring to allow us to have virtually unlimited block & item IDs. But we fully expect everything to break. Please make backups.
本次快照代表了这几年来内部重构的努力，来使得我们能真正拥有无限的方块和物品ID。但我们已经做好了所有东西坏掉的准备。请先备份
