+# Minor soundness issue with Decoder's Send trait
+
+Affected versions of this crate implements `Send` for `Decoder<R>` for any `R: Read`. This allows to use `R: !Send` in `Decoder<R>` to send a non-Send type to another thread.
+
+This can result in undefined behavior such as memory corruption from data race on `R`, or dropping `R = MutexGuard<_>` from a thread that didn't lock the mutex.
+
+The flaw was corrected in commit a34d6e1 by adding trait bound `R: Send` to the `Send` impl for `Decoder<R>`.
