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.
The mission of the YUI team at Yahoo continues to be to deliver the best next-generation presentation technologies with an initial focus on internal developers. We remain optimistic about the future of web presentation technologies and are eager to continue working with the external frontend community to share and learn together.
