What is the difference between Android 4.4W (API20) and Android L (API20, L Preview) in the SDK Manager?

I'm updating my SDK Manager in Eclipse, and there are two new downloads:
我正在 Eclipse 中更新我的 SDK 管理器，并且有两个新下载：
Android L (API20, L Preview)
Android L (API20, L 预览版)
Android 4.4W (API20)
安卓 4.4W (API20)
I'm confused because they're both referred to as "API 20". And I'm not sure what the "W" in "4.4W" is referring to.
我很困惑，因为它们都被称为“API 20”。而且我不确定“4.4W”中的“W”指的是什么。
