CubeMX v.6 reset preemtion priority to 0 in projects whith FreeRTOS.
Hi !
What a trouble in new version of CubeMX 6.0 ?
Why :
1. CubeMX v.6 reset preemtion priority to 0 from any nonzero values in projects whth FreeRTOS when to migrate from old version?
This is original setting:

this is migrated to 6:

2. Where a checkbox "Uses the FreeRTOS functions" in NVIC tab ?
STM Employes, answer please, another way need to return to old stable version 5.6.1.
