- Based on C++11's `mutex` - No more need to allocate-deallocate or check for null - No pointer anymore, just a member variable - Platform-specific implementations no longer needed - Simpler for `NO_THREADS` - `BinaryMutex` added for special cases as the non-recursive version - `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`. - `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
