Hello,
I found a bug and Im almost sure it is in clear instalation of prestashop 1.7
If it is last day of "newest" limit days, prestashop dont add "new" label to product. For example if you set 45 days for "new product" life and one product life is 44 days and 2nd is 45 days then both are on list "new products" but only one got label/flag "new". Am i right? Can you help me to fix it? I think it need to be "<=" and it is "<" in function checking limit life of new flag.
