Why does it matter is it was commonly known as Episode V in  or not Thats an argument for changing the article title not for listing an aka The fact is its very commonly known as that now and it has always been the onscreen title just not the promotional one Saying it was later released as that is at best incredibly misleading and at worst just a flat out lie Not even the Special Editions were promoted that way if thats what youre going by for example Changing it to say also known as would be much more accurate
