FDA registration require update to product listings in June and December?

[Mabel Adams]

"Establishments must be registered and products listed within 5 days of beginning operation, and annually between October 1 and December 31. Blood product listings must be updated every June and December." is from https://www.fda.gov/vaccines-blood-biologics/biologics-establishment-registration/blood-establishment-registration-and-product-listing.

Does anyone know what we were required to do in June?  If nothing changed in our product listing was I supposed to have done something on the CBER site in June?
