我的世界Minecraft Java版17w48a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，17w48a为其第8个预览版。

一点警告
This snapshot should be considered "fairly experimental, dude". From a scale of 1-10 where 1 is experimental and 10 is stable, this is a tentative 3.
这个快照可以说是“非常，非常试验性”的。如果1到10里面1是实验性的而10是稳定的话，这个版本代表的数字应该是试验性的3。
Back up your worlds before trying them in this snapshot. Don't expect worlds played in this snapshot to work in future snapshots. Don't expect worlds played in last weeks snapshot to work in this weeks snapshot.
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。不要指望在上一个星期的快照中玩过的世界到这个星期的版本中还能玩。

They broke in last weeks snapshot, but we forgot to update the format number so they didn't warn you in game. We've fixed that and now every outdated resource pack will warn you if you try to use it.
在上一个星期的快照中它们不能使用了，然而我们忘记了更新资源包的版本号，因此你并没有在游戏中得到提醒。这次我们进行了修复，也就是说如果你试图使用过时的快照，游戏会警告你的。
