The Yahoo! User Interface development team has released the first preview version of YUI 3.0. According to the team blog, there are 5 goals for the new release: lighter code (in kb), faster code (fewer HTTP requests, more compact code), greater API consistency, more powerful API capability, and more securable code.
For those who don't like the jQuery-style fluent interfaces in YUI 3.0, a more explicit/verbose API is still available. YUI 3.0 will not be completely backward compatible with YUI 2.0, but there will be a limited compatibility layer.
You can download the preview release here. A final release is not anticipated until next year.
