UDT not working on SubD objects

SubD object cannot be deformed with UDT tools like CageEdit, bend etc. Is this a temporary bug?
I remember I could use UDT on SubD objects earlier.

Maybe off-topic question here but do I need to install WIP R7 for latest Sub-D functionality or are all features integrated into latest build of R6?

You need to install the latest WIP

OK, thanks.

The reason why I asked is because when you type for example SubDFromMesh -> it will be not auto-completed in R6 but still command will work after Enter is pressed.
