This release features an upgrade from YUI 2 to the newly released version 3. The whole library is now included as part of the Onpub download to make it easier to start using the now built-in YUI Loader functionality. All Onpub UI code that previously relied on YUI 2 has been rewritten to use the new YUI 3 libraries. CKEditor has also been upgraded to the latest nightly release.
These upgrades put us in a position to make some great user interface improvements in upcoming releases.
