Copter-4.3.3 released!

anyone has used 4.3.3 with Hereflow V4 for indoor Loiter flight mode?

I experience that 4.3.3 does not allow the pilot to move the UA when switched to Loiter flight mode. I have 90 (EKF Pos Source) low is GPS, the middle is OpticalFlow, high is unused set up.

It is like 4.3.3 wanting to “glue” the drone to the spot and not letting the pilot fly and fighting with the pilot. It starts to oscillate. Did anything get to do with SURFTRAK_MODE? SURFTRAK_MODE is set to zero to solve the high oscillation issue.

Prior to this flight, redo autotune successfully.

[Update]
It seems to have to do with these Loiter values I had set.
It could be Hereflow 42° FOV “see” part of the landing gear (investigating)
LOIT_ACC_MAX,500
LOIT_ANG_MAX,0
LOIT_BRK_ACCEL,250
LOIT_BRK_DELAY,0.5
