"Welcome! You definitely missed out on some (neurotic) fun last year!
It appears that the update reflects NDSEG administrators updating the status of your application on that date, but it doesn’t actually say what that status change was.
If you check out last years thread, we noticed the dates back in April while we were waiting for award results. At the time, some people had a december update and some people had an april update. Then as the days passed, the april people kept getting another update here and there.
When awards were released, all of #decembergang was rejected. Some of the April people were awardees, some were waitlisted, and some were rejected.
We concluded that if you didn’t have an april update, you were cut back in December. BUT, Since we only started looking for this in April, its unclear what updates happen in November through April. (Ie. Did everyone get an update on in december? Were there February updates? Its unclear.) I think a natural hypothesis for now is that a November update means your application was marked as complete and will be evaluated, but it’s impossible to know with certainty.
Also, we made a spreadsheet: https://docs.google.com/spreadsheets/u/2/d/1HHwP8Zyh8W24HRUh5WnObRExb24JhN5ZLTa7p5Q8CkI/htmlview#gid=0"
