YUI 3.0.0
Ich verwende YUI zwar nicht häufig, beobachte aber was da so passiert und YUI 3 bringt einige feine Features mit, z.B.:
Self-completing: YUI 3’s light (6.2KB gzipped) seed file can serve as the starting point for any implementation. As long as this seed file is present on the page, you can load any module in the library on the fly. And all modules brought into the page via the built-in loader are done so via combo-handled, non-blocking HTTP requests. This makes loading the library safe, easy and fast.
