Changes

Detect Deadlocks: when two or more threads are permanently stuck because no thread will give up its current lock until it can take the next one. But that lock is being held by another thread in the same position.

Detect deadlocks & data races: will do exactly what I explained earlier plus detect data races. Data races is when the outcome of an operation can change depending on what order the thread reached in.

Locate deadlocks & data races: is more detail with a smaller granularity deeper default stack frame depth and configurable scope.
