Hi,
I am sorry but the update does not touch any HikaShop configuration option in the database.
More than that, the default folder is "media/com_hikashop/upload/" so I really don't know why this folder should be changed to something different and not related to HikaShop.
There is an option in the HikaShop backend to select the upload folder (and the secure upload folder).
Folder where the images are uploaded and the thumbnails are generated.
