I saw this last night on FamilySearch: FamilySearch Updates Enhance your Experience May 29/30, 2019: https://www.familysearch.org/blog/en/familysearch-updates/.
FamilySearch is proud to have the world’s largest online family tree and thrilled to provide free family history experiences to millions. In order to give users the best experience possible, we are constantly working on updates and improvements to our online experience.
To keep you up to date on the latest FamilySearch experience changes, we will be listing them here chronologically. Check back often to see how your FamilySearch experience has improved!
Update: May 30, 2019—Standardized Dates and Places
A system-wide update will standardize many dates and locations in the FamilySearch Family Tree. In the View Details section, these changes will appear with the contributor listed as “FamilySearch” and the date changed to May 30, 2019. This will occur for vital and couple relationship conclusions only and will not trigger users’ Watch Ancestor notifications.
This update will help users by removing the data problem “Missing Standardized Date,” and “Missing Standardized Location”, saving the user time. It will also assist the site in providing more accurate record hints and creating more reliable data. Standardized dates will help you find ancestors more easily when you search the entire site.
Approximately 25 million of the 172 million dates and places missing a standard on the FamilySearch Family Tree will be affected.
