4.60.0.4
New location parameter option for Windows. Setting location=None tells PySimpleGUI to not set any location when window is created. It's up to the OS to decide.
The docstring for Window has been changed, but not all the other places (like popup). Want to make sure this works before making all those changes.
4.60.0.5
Added check for None invalid values parm when creating a Listbox element
