Does B5 AI stabilization work for Pocket4K?

Release notes don't specify.

"Support for the Blackmagic Pocket Cinema Camera 6K G2.
Ability to stabilize Blackmagic Pocket Camera clips using AI and camera gyroscope metadata"

I know the 4K has some kind of gyro in it, but understand that the older hardware might not be compatible. Fingers crossed anyway.

Yes, all (now four) models of Pocket should work.
