# September 1st, 2024

In this release, we've made an important change to participant management which allows for the preservation of previous period mappings. 

If a Site Admin user makes a change to a participant list, the previous period demographic mapping will be updated and any mapping work already done will be preserved.

Changes can be made either by uploading a .csv or with inline page editing.
