The <rich:popupPanel> no longer ignores the min and max sizes for width and height when autosize=true.

The <rich:extendedDataTable> now has built-in sorting and filtering controls. If you have existing <rich:extendedDataTable> with custom sort and/or filter controls, you will want to disable the built-in sort and/or filter controls. This can be done either on a column-by-column basis, or for all columns in your applications.

For details on disabling the built-in sort and filter controls, refer to sections "External filter controls" and "External sort controls" in the RichFaces Component Reference.

Prior to version 4.3.0.Final, the message summary and details of the <rich:notifyMessage> and <rich:notifyMessages> components were not escaped. In the 4.3.0.Final release, an attribute escape was added with a default value true.

The <rich:select> now validates that manually entered input values match one of the values of the provided list (including support for client-side validation).
