Improvements
- embOS libraries including the workaround for the Arm Erratum 837070 (ARM-EPM-064408) now preserve and restore the PRIMASK register with calls to OS_INT_Disable() and OS_INT_Restore() per default.
Program corrections
- embOS Cortex-M33 libraries without FPU support and with TrustZone support used a wrong exception return value when starting OS_Idle().
The problem existed since embOS-Ultra for Cortex-M IAR version 5.16.0.0 and is fixed with version 5.18.0.0.
