ExtJS 1.1 released
This version includes the library itself, a simple WYSIWYG HTML editor, a new Ext.Ajax utility class, improved DateField and DatePicker components, as well as extensive documentation and corrections.
The most pleasant innovation is the independence of the library from third-party products and the minimum size of the base library (36 KB).
