Inside the rich history of The Church of Jesus Christ of Latter-day Saints, changes in policy, practice, and place are not unfamiliar. Updates from the First Presidency and other Church executives, through both revelation and evaluation, are frequently made, and while some changes are more impactful than others, all adjustments are felt by the members involved.
