-- Fixed race condition that causes cancellation of one download operation to stop a run loop that is now used for another download operation. Race is introduced through `performSelector:onThread:withObject:waitUntilDone:` - [#698](https://github.com/rs/SDWebImage/pull/698)
-- Fixed race condition between operation cancelation and loading finish - [39db378](https://github.com/rs/SDWebImage/commit/39db378) [#621](https://github.com/rs/SDWebImage/pull/621) [#783](https://github.com/rs/SDWebImage/pull/783)

For all the other platforms (tvOS, watchOS) we will fallback to the backwards compatibility feature described above
