Was it noted somewhere that the PRORES LT firmware unlocks 6K 60FPS to a standard CF Express card?

I was just wondering because I was shooting a wedding yesterday, and to my surprise, I could switch to 6K 60FPS (with a crop).  I don't record being able to do so before the update.

Hi, there.
Sorry for the late reply.
We have confirmed with the team, it is normal if you updated your firmware to the latest version.So please feel free to use it.
If there is anything else that we can help with, please let us know  
Thank you.
