ALERT: Fidelity restored the CSV format back!! Read before running F2O.py

[Cal Learner]

ALERT: they changed my "Accounts_History - 2026-07-10*.csv" back to the OLD format!!  What timing! There had been some complaint about having changed, and they actually put it back.

So I will need to 

1. Restore my latest backup  --  in my case 07/08/2026  08:07 PM

2. File->RestoreFromABackupFile.

3. Note that I had transactions dated 6/8/2026 in my registers

4. set  IGNORE_BEFORE_YYYYMMDD="20260709" in my F2O_cfg.py file.

5. Re-run F2O, which in my case is to run F2OPS.bat.

-------------------------------------

I then checked the balances to see if there were any missing or duplicate transactions. Balances matched.

What I did not check is if they are exactly the same, but if they are, those who did not get new CSVs  in the interval between about June 29 and July 10  may have never noticed a glitch or event.

There had  some Reddit discussion on the CSV change and the impact to others.

Additional info:

Amerdan reports the CSV format change only partially reverted, so
1. You will need still a  version of F2O.py from July, preferably the newest.  F2O_beta21.zip is currently the latest in https://drive.google.com/drive/folders/1-4fBbRxaPhNYZK0gNHuZ3n-Bdoncy2aR
2. You will still need to set up the  IGNORE_BEFORE_YYYYMMDD="20260709" in your F2O_cfg.py, even if your newest transactions were from June 27 or before.
