Getstatistic.jsp caching

I use the API getstatistic command to get the year’s energy totals for generation and consumption. So I set dt to today’s date and df to the date one year ago at midnight. Before August this year I could see the totals increase over the day, but recently I see only totals that stay constant during the day. Was the caching behaviour changed?

When a date range is used the cache will last 48hrs.

Thank you for the information. That explains the behaviour I see.
Was this policy changed per 1 August 2025?

It would have been around that time.
