Format change of statistics_s1.json.gz

[bakerkj]

Hi it appears that the format of https://data.blitzortung.org/Data/Protec...s1.json.gz changed recently.

Previously it contained in addition to other fields:
  - all
  - member
  - valid
  - used

Now it contains:
  - total
  - valid
  - involved
  - used

Is there documentation of this change somewhere?

Thanks,
Ken
