The first datasets I'm looking at haven't been updated in 9 months: https://data.nasdaq.com/data/FRED/DGS10-10year-treasury-constant-maturity-rate

There's no way for me to ask about it because all the help links 404 on https://help.data.nasdaq.com/category/339-data-quality-issues which is the page that came up on Google

This library hasn't been updated in 6 mos and looking at the code here makes it quite unclear who should be contacted as it seems the contact info was possibly supposed to be updated months ago and it never happened for some reason: #29
