Hello, it's me again, here is my second bug report today.

After update to 1.15.0beta I found my diamond sword(been enchanted with sharpness V) did less hurt than before, so I test the hurt of enchanted diamond sword and find it did less harm, really.

The test goes like this, I make three diamond swords in creative mode which have features as below:  1.just diamond sword,2.diamond sword enchanted with sharpness V(it will cause 13 hurt to mobs) 3.diamond sword enchanted with smite V(smite were translated as death killer in Chinese😂)

After that I spawn three zombie pigmans(or zombiefied piglin as his new name in Java edition?) and try to do harm to them(in survival mode). All three swords shows no difference on their damage: three attacks to kill one pigman. Swords enchanted sharpness V and smite V should kill it within two attacks. I don't know why it happens.

It is not a big bug for me but it may disturb some new players. 

Wish you a whole good year!
