Cam_min_interval missing?

I’m not sure what’s going on here. Running mission planner 1.3.39.1 and documentation online suggests that Cam_Min_Interval might solve my camera triggering problems but I don’t see it in the full parameter list. I tried to update to beta MP but windows is giving me errors and the update fails. Aircraft is a 3DR Iris+ running AC 3.3.3

Thanks!

That feature did not make the copter 3.3 release. It is in master as well as 3.4.

3.4 is still in beta, no?

I do want to play with 3.4 though to see how the lidar precision altitude is working.

Correct, 3.4 is still in beta.
