You can can also review the summary of all changes noted in the component history files for YUI 3.4.1 as well as the full list of tickets addressed during YUI 3.4.1 development. As always, we would appreciate that you file any suggestions you might have or defects you might uncover in our ticket database. Feedback for YUI 3.4.1 can be entered in the YUI 3 ticket database.
We would also like to announce that in the next release of YUI, DataType.Date, DataType.Number and DataType.XML will be deprecated in favor of Y.Date, Y.Number, and Y.XML, respectively. Backwards compatibility will be retained for one release, to give everyone a chance to switch over.
