The incompatibilities with macOS 10.5 Leopard have been solved.
On Leopard, menu icons have been redesigned to match the new interface.
On Leopard, the System Memory submenu now expresses page ins and outs (and copy-on-write, zero filled, and reactivated pages) in terms of their total memory, consistently with Activity Monitor.
The iPhoto Library submenu now fully supports iPhoto ’08 and lets you view your library by event and show recent events, flagged photos, web galleries, and your current print project. In addition to that, Application Wizard now correctly previews items that were imported to the iPhoto ’08 library without copying them to iPhoto.
A bug that caused the Application Wizard Installer and preference pane to quit unexpectedly in presence of a malformed login items preference file has been fixed.
Some other minor improvements and fixes have been introduced.
Minimum required system version is now macOS 10.3.9.
