New event spark/device/last_reset -> panic, stack_overflow?

Hi, Is this event or its details new? Since when?
I don't recall seing it before.
Seen on a device just updated to 4.2.0:

Now let's troubleshoot that stack overflow issue, 100% chances is my code :expressionless:

At least as far back as 0.8.0-rc.25! Not every panic code has a name displayed, but the common ones are (memory_fault, bus_fault, usage_fault, out_of_heap, assert_failed, stack_overflow) and the others have the panic code number.
