4.0.0

• Increased Swift version to 5.7
• Increased minimum target versions

3.2.0

• Allow Locked to store non-Sendable elements

3.1.0

3.0.0

Remove SynchronizedDynamic dynamic library.

2.3.0

Expose SynchronizedDynamic dynamic library in addition to the static library.

2.2.0

Improve correctness of Lock and RecursiveLock by calling UnsafeMutablePointer.deinitialize() in deinit. Also, potentially improve safety of RecursiveLock by backing it directly with UnsafeMutablePointer<pthread_mutex_t> instead of pthread_mutex_t, which might help avoid problems caused by Swift's ampersand operator.

2.1.0

Changes tryLocked() to return Bool from to indicate success or failure of acquiring the lock.

2.0.0

Removes the Synchronized protocol in favor of directly exposing Lock and RecusiveLock for use by client.

1.2.1

Reduce lock contention when cleaning up locks for deallocated objects.
