YUI 3.0.0 beta 1 Available for Download » Yahoo! User Interface Blog
YUI 3 moves out of preview and into beta releases. With this move, the API is nearly final, and there are some performance improvements. We've been using YUI3 on Launchpad. All of the AJAX work on Launchpad has been YUI3 driven and is running on launchpad.net now. I've been pretty happy with YUI3 personally, but I realize JavaScript libraries bring out the best and worst in developer opinions. At any rate, it's nice to see YUI3 getting closer to final release.
