New features added to the new, modern user interface in this release include:
Memory Debugging Block NotifyThis release adds the ability to watch a specific allocated memory block and raise an event when it gets freed or deleted. This is useful when a specific block of memory is freed, but your program accesses the memory later through a dangling pointer reference. At this point, the memory may or may not still contain valid data and typically results in sporadic crashes or data problems in your program.
This feature is not yet covered in the product documentation, but detailed notes regarding its use are in the 2022.1 Release Notes.
