Release Notes: XML is used for all file formats. The previous file format is supported but only XML is saved. The code generation changes were made for escaped special character values. QHGroupBox, QIconView, and QVGroupBox widgets were added. The properties for all widgets have been updated.
Release Notes: Internationalization (Qt Architect now supports the Qt 2.0 mechanism for internationalization; a dialog can now be fully internationalized, and Qt Architect itself is now internationalized, but there are no translations available yet; volunteers to translate the 800+ text strings used by Qt Architect would be much appreciated), and support for the new Qt 2.0 widgets and any of the built-in widget styles.
Release Notes: Version 1.4-4 now includes support for plugin modules. Modules can be written for third party widgets. A KDE 1.1 reference module has been included as well.
