There have been several rule changes over the years actually. Here are the changes since 1970, minus any Rule 10 changes, which frankly, who cares about?

1971 - Batters required to wear helmets. Rule 1.16
1973 - American League votes to accept DH on a 3-year experimental basis. National League votes no. Rule 6.10
1974 - Umpires no longer need physical evidence to call illegal pitch, and can warn pitchers if the pitched ball behaves in a strange manner, with ejection on next illegal pitch. Rule 8.02
1975 - Baseballs can be covered in cowhide as well as horsehide. Rule 1.09
Cupped bats allowed. Rule 1.10
1976 - A.L. makes DH permanent. Rule 6.10
1988 - Helmets made mandatory for catcher. Rule 1.16(d)
1996 - The latest strike zone change. Rule 2.00
