Some of you know that me and /u/MansOlson have been working on a new Minecraft launcher for some time now, and we're ready to show it off and get some testing on it!This new launcher is completely native, doesn't use Java at all. We were able to make it much faster than the current launcher, give it new things that you can't currently do... and it looks just so much better!
We currently have a build for Windows and OSX, but we'll try to have a Linux one ready for testing shortly. Please let me know if you encounter anything that you think behaves weird, doesn't do what you expect, or just outright crashes. We'll also accept any general feedback, like "I think it looks ugly (here's why, and here's what I think would look better)" or "I really like how fast it is!". Any feedback is good feedback!
我们已经有了Windows 和 OSX版本，但我们将在不久之后让LINUX版本公布测试。如果你遇到了任何事物运行的很奇怪，做的事和你想象的不一样，或者崩溃，请让我们知道。我们也接受任何其他的意见，比如“我觉得这里很丑（为什么还有怎么改能漂亮）”或者“运行的真快我真喜欢！”。什么意见都是可以的！
It will run separately from your current Minecraft launcher, but will use your current settings/worlds/etc. However, if you choose to go back to the old launcher then it will erase your launcher settings (such as login credentials) and you will have to log back in again. Sorry! (You can find a backup of the launcher_profiles.json in your game directory though, when downgrading.)
At the end of this public test, the launcher will alert you that the full version is out and your regular launcher will update automatically. You can then delete this test version.Please note that this is an experimental test version and may be buggy or outright broken!
