· calendar image Calendar (beta): Allen Rabinovich has added Calendar to YUI 3's collection of widgets in the 3.4.0 release. Calendar is a flexible widget that provides month-to-month navigation, single or multiple date selection, custom formatting and internationalization. It also introduces a novel approach to date filtering that uses nested rule sets, and a fully template-based rendering, which allows developers to quickly and easily customize it for a variety of uses.
· Loader: The YUI Loader has undergone a significant update for 3.4.0 by Dav Glass, with a focus on improving performance. The seed file contains Loader and its meta-data which makes the loading of modules faster since all of its meta-data requirements are already on the page. Rollups have been removed from the system and allowRollup defaults to false in the Loader config. As a result,YUI will now only load the modules specified rather than additional modules included as part of a rollup. Finally, the build directory has been exploded and submodules have been removed from the core system reducing the number of iterations executed by Loader in the calculation of dependencies. You can refer to the blog post about Loader changes in 3.4.0 for more details.
· Panel (beta) and Widget: YUI intern Tilo Mitra spent another productive summer in California working on a rewrite of Panel. He has also made several enhancements to Widget including the conversion of Widget-autohide and Widget-modality from plugins to extensions, and the introduction of WidgetButtons, a new Widget extension that allows you to place css-styled buttons in the header and footer of any widget that implements standard module support.
· ScrollView: Tilo has also enhanced ScrollView for 3.4.0 to support vertical paging and include a scrollview-list plugin to add CSS classnames to immediate list elements.
· Loader has had a significant update for 3.4.0.
· Calendar and Panel are fully functional and ready for developer use.
· Graphics: There have been a few API changes that will affect any experimental code written on the Graphics API distributed in the PR2 release. getShape() has been renamed addShape().
· Transition: Native transitions are now supported in FireFox.
· WidgetButtons has been released as a new Widget extension that allows you to place css-styled buttons in the header and footer of any widget that implements standard module support.
· Widget-Modality and Widget-AutoHide plugins have been converted to extensions.
· Widget: Added support for destroy(true) which will remove and destroy all child nodes (not just the boundingBox and contentBox) contained within the Widget’s boundingBox. destroy() will maintain its current behavior due to the potentially high run-time cost of destroying all child nodes. If you destroy Widgets in your application or are a custom widget developer, your help in testing this change would be appreciated.
