Yad (Yet Another Dialog), a fork of Zenity with many improvements, such as custom buttons, additional dialogs, pop-up menu in notification icon and more, is now at version 0.24.0.
The developer has explained his reasons for this fork. One of them is to remove dependencies on deprecated libraries, such as libglade and gnome-canvas. The other reason for the development of Yad is the fact that Zenity seems to have been abandoned.
Highlights of Yad (Yet Another Dialog) 0.24.0:
• The --auto-close option has been added for the multi-progress dialog;
• The --image-path option has been implemented;
• The --no-click option has been added to the list dialog;
• Clear text has been added in the text-info dialog.
Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.
