Hey everyone! It's Friday again, which means it's time to fire another callback for YUI Weekly! We've got two weeks of YUI news to catch up on because of the holidays, so this one's going to be packed.

Release News

We released YUI 3.14.0 on November 25th, notably containing major improvements to Charts and the work we've started to do to let developers use ES6 modules with YUI. We also got a lot of great contributions from the community during this release, so a big thank you to everyone who helped to make YUI better.

It's available for you to use directly off our CDN, as a zip, or installable through npm.

You can see the full list of all of the changes in our release rollup right here. Please definitely let us know if you come across any bugs by filing an issue on GitHub.

Open Roundtable

This week's Open Roundtable kicked off YUI in the Wild, a new Roundtable series we're starting based on the 'In the Wild' blog posts from quite a while back!

For our first guest, we had Jeff Pihach from Canonical come in to talk about building Ubuntu Juju's GUI using YUI. He showed us how the Juju team structured their YUI App Framework application, how they bundled together their modules for a long-running app, and how they extended Y.Router to create URL flags for beta application features. Check out the video for all of that, and a lot more!

The Juju GUI is open source, so you can go and check out their source code online!

If your company or team is interested in being featured on the next YUI in the Wild, feel free to contact Andrew Wooldridge, our Community Engineer, and we can help you set up a time or discuss content!

New this Week

The World of JavaScript

• Happy 18th birthday to JavaScript! It's been 18 years since JavaScript was first announced by Netscape and Sun, and it's definitely come a long way since then.

• Check out the latest part in Ariya Hidayat's Kinetic Scrolling series that shows us how exponential decay can help create more natural scrolling! Look out for both of Ariya's YUIConf 2013 talks as well, coming out soon!
