v3.3.0

• Add a forget() method for semaphore guards. (#73)
• Increase MSRV to v1.60. (#75)

v3.2.0

• Add missing methods for blocking on locking with types wrapped in Arc (#71).

v3.1.2

• Bump event-listener to version v4.0.0. (#69)

v3.1.1

• Add a note to the documentation comparing this crate against libstd's locks. (#58)

v3.1.0

• Add a Default implementation for OnceCell (#63).

v3.0.0

• Breaking: Add an enabled-by-default std feature that allows using this crate without the standard library. (#43)
• Support blocking and non-blocking operations on the same locks. (#56)
• Switch to a more efficient event notification mechanism. (#43)

v2.8.0

• Fix a bug where the SemaphoreGuard::acquire_arc future would busy wait under certain conditions (#42).
• Add a Semaphore::add_permits() function to increase the number of available permits on the semaphore (#44).
• Make RwLockReadGuard covariant over its lifetime (#45)
• Add RwLockReadGuardArc, RwLockWriteGuardArc, and other reference counted guards for the RwLock type (#47).
• Loosen the Send/Sync bounds on certain future types (#48).
• Fix UB caused by the MutexGuardArc::source function allowing the user to drop an object in a different thread than the one it was acquired in (#50). This is a breaking change, but in the name of soundness. Therefore it doesn't break any valid behavior.
• Fix a bug where this crate would not compile properly on wasm64 (#51).

• Replace some async blocks with manual futures (#34)
• Remove our dependency on futures-lite (#36)
