# Queues allow non-Send types to be sent to other threads, allowing data races
Affected versions of this crate unconditionally implemented `Send` for types used in queue implementations (`InnerSend<RW, T>`, `InnerRecv<RW, T>`, `FutInnerSend<RW, T>`, `FutInnerRecv<RW, T>`).
This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior.
The flaw was corrected in v0.1.7 by adding `T: Send` bound to to the `Send` impl of four data types explained above.
