what the hell?

Two notes at  https://fred.stlouisfed.org/  on 3 december:

• Take note: FRED has updated some series names
•  Discontinuance of St. Louis Monetary Base and Reserves Data

And then this morning M1 Money Multiplier turned up in search results. (I didn't even know they had that series.) I laughed, because some people have such tantrums about the multiplier, then went to have a look.

What struck me is this, from the notes:

Updates of this series will be ceased on December 19, 2019. There is no direct replacement to this seasonally adjusted series. Interested users can construct a proxy ...

Change is upsetting.

The really strange one is the discontinuance of base and reserves data. That sounds more like an overhaul of Fed doctrine than a perchance budget-related matter.
