HEAD条目是用户应集成的主要代码流(如果它们需要自己分叉并稍后与HEAD流合并，这主意不错)。

The HEAD stream is the main code stream that users should be integrating to (if they want to branch off on their own and then merge with the HEAD stream later, that's fine).

如果我们等到sprint结束再做，任何分叉的代码就会在错误的时刻发现——此时我们能够用来修复问题的时间最少。

If we wait until the end of the sprint to do this, any diverging code will be discovered at precisely the wrong moment - when we have the least time to fix it.
