CVE-2020-35924: Data races in try-mutex

August 25, 2021 (updated June 13, 2023)

Affected versions of this crate unconditionally implemented Sync trait for TryMutex type. This allows users to put non-Send T type in TryMutex and send it to another thread, which can cause a data race. The flaw was corrected in the 0.3.0 release by adding T: Send bound for the Sync trait implementation.
