I recently noticed that within Pages ('09), Numbers ('09), Keynote ('09), the menu entry:
- File > Save As…
had been replaced by a new one:
- File > Duplicate
On the other hand I still use this function within some other applications like LibreOffice (188.8.131.52) without a problem. I suspect this change isn't a system wide one.
I didn't get any notice of this change of a key function in file management within any recent upgrade.
When did this change appear?
Which upgrade performed this change?
