is not exactly a upgrade, i was developing in my localhost with the 3.32 version, when i finish to made all the changed desired i see the 4.02 version is avalaible.
I install the 4.02 (fresh instalation) both in my localhost and my remote server, then i (create categories etc...) modify the showproduct template.
But the google map do not appear, i think it was a problem of diferences between local server and remote server , and copy directly the old showproduct.tmpl of my local server to the new 4.02 directory of my local server but the map do not show.
for this i think there are a problem in the 4.02 version with the google map script.
i can send you a screen capture and the tmpl file if you need it.
