- Based on C++11's `thread` and `thread_local` - No more need to allocate-deallocate or check for null - No pointer anymore, just a member variable - Platform-specific implementations no longer needed (except for the few cases of non-portable functions) - Simpler for `NO_THREADS` - Thread ids are now the same across platforms (main is 1; others follow)
