For the daytime version (excluding the pilots and the Goen version), here is a list of all the dates for which I've been able to verify the complete Wheel template layouts:
 * January 6, 1975


 * November 3-7, 1975 (special hour-long week)


 * January 19, 1976 (likely introduced December 1, 1975, though unconfirmed)


 * May 20-June 7, 1976 (Round 2 verified still in use on January 28, 1977; others may have still been in use as well)


 * January 18-March 15, 1978 (Round 1 used on two date-unknown 1977 episodes)


 * April 6-October 20, 1978 (Star Bonus likely elimiinated sometime during this period)


 * March 2-June 1, 1979


 * December 4-31, 1979


 * March 18-25, 1980


 * May 7, 1980-September 21, 1981


 * December 25, 1981-April 12, 1984


 * September 17, 1984-June 20, 1986


 * September 15, 1986-June 30, 1989

Special notes regarding the July 15-September 5, 1975 period: (1) some 2-digit spaces eliminated by July 15; all were verified changed by September 5

(2) presence of Buy A Vowel not confirmed for Rounds 2-3, as it was neither landed on nor mentioned

(3) Round 3 presumably used same template as Round 2, barring the continued use of the extra Buy a Vowel
