Yahoo Drop the Axe on YUI
Yahoo has just announced they will immediately stop all new development on Yahoo User Interface (YUI). Julien Lecomte, Director of Engineering at Yahoo Presentation, made this revelation in the Yahoo Engineering Tumblr blog and stated: "We have made the difficult decision to immediately stop all new development on YUI in order to focus our efforts on this new technology landscape".
The development of YUI started in 2005 by Thomas Sha and was sponsored by Yahoo co-founder Jerry Yang. The first public release was in February 2006 and since then a core team of Yahoo engineers has actively developed it. In September 2009, the latest major version of YUI (YUI3) was released. It represented a rebuilt from the ground up to contemporize the library and integrate lessons learned from YUI2. Among the enhancements were a CSS selector driven engine for retrieving DOM elements, a greater emphasis on granularity of modules, a smaller seed file that loads other modules when necessary, and a variety of syntactic changes intended to make writing code faster and easier.
Although Yahoo stopped new developments, critical bugs will still be addressed:
New YUI releases will likely be few and far between, and will only contain targeted fixes that are absolutely critical to Yahoo properties.
