YUI 2.9が 2系の最後のメジャーアップデートになるらしい

YUI 2.9.0 Release Update » Yahoo! User Interface Blog (YUIBlog)

YUI 2.9.0 will be the last major dot-release of the 2.x codeline, and the team will be aggressively reviewing all open tickets against the YUI 2 project and either assigning them to be a part of the 2.9.0 release, closing them as “WON’T FIX”, or moving them to the YUI 3 project.

これが終わったらGoogle JavaScript Libraries APIも3系に移ってくれるのかなー？
