YUI 2.7.0 Released

Tagged:  

The Yahoo! User Interface team has released version 2.7.0 of its JavaScript framework library. The new release brings official support for IE 8 and graduates some components out of "beta" (Element, ProfilerViewer, and Selector).

What's new?

  • The YUI StyleSheet Utility. Allows you to create and modify CSS stylesheets on the fly. It addresses the need to apply style or style changes to multiple elements in a more efficient way--using dynamic CSS--than traversing the DOM and applying changes directly, which generally incurs the cost of a page reflow for each change.
  • The Charts Utility gains several new additions, including rotated axis labels/titles and new series styles that allow greater control over look of the chart lines, borders, and fills.
  • Many enhancements and fixes to the TreeView Control. Improvements include multiple selection node highlighting (including propagation up/down) and better focus/event handling.
  • The addition of new methods to the DOM Collection, including getComputedStyle(), getElementBy(), setAttribute(), and getAttribute().

All together, there were over 180 bug fixes and enhancements in the release. You can download YUI or use the YUI Configurator to select a custom component mix.
