Version 0.12.1 of the Yahoo User Interface Library (YUI) was released this morning. This minor update focuses on bugs and issues raised since 0.12.0; no new features are introduced in this release.

Among the improvements you'll notice in 0.12.1 include significant performance boosts for Slider when used in Firefox, particularly when the Slider's DOM elements are deeply nested in the DOM.

YUI version 0.12.1 is available for download now from SourceForge.
