Questions tagged [yui]

A set of utilities and controls, created by Yahoo in JavaScript and CSS, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX

The YUI (Yahoo! User Interface) library provides tools for professional web development, including a rich JavaScript and CSS library -- all freely available under a liberal BSD license.

Active development of YUI was discontinued by Yahoo! on August 29th, 2014, based on the following:

Most core YUI modules do not have active maintainers, relying instead on a slow stream of occasional patches from external contributors. Few reviewers still have the time to ensure that the patches submitted are reviewed quickly and thoroughly.

Therefore, 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. This means that, going forward, new YUI releases will likely be few and far between, and will only contain targeted fixes that are absolutely critical to Yahoo properties.
