Nerfs are changes to a character that make them overall worse than they were before.
Buffs are the opposite of this; the character is made overall better by this change.
Neutral Changes are subjectively-good/bad changes, such as bug fixes or reworks.
When deciding whether a move is a Nerf, Buff, or Neutral Change, it's important to consider the intent behind the change as well. For example, the All-Star Battle R patch notes sometimes come with descriptions detailing the reason behind a change to a character.
