PrestaShop v22.214.171.124 Stable
Be aware that this version effectively prevents new customers from signing up using names where a dot is not either at the end of the name or separated by a space. For example: "John R.Hammond" won't be accepted but "John R. Hammond" will.
On existing shops, you may be customers who have already registered using this kind of name. In that case, they may be required to update their names by removing dots, adding a space after any dot, or replacing all dots by spaces.
