Unless they change weaknesses which i don't think pokemon does
They did change strengths and weaknesses in generation 2. In the original games, Bug was 2× against Poison but now it deals ½×. Poison used to be 2× against Bug but now it's only 1×. Ghost dealt 0× damage against Psychic, but now it's 2×. Ice used to deal 1× damage against Fire but it was changed to ½×.
