+
+### What's New
+
+- Classes
+    - `MultiLock` for managing multiple locks as one.
+
+- Utilities
+    - `lock()` function for joint locking of multiple locks.
+
+### What's Changed
+
+- Fix bug in `tryLock()` utility function. Error was not being re-thrown if it occurred on the first lock.
+
+## [2.0.6](https://github.com/havelessbemore/semafy/compare/v2.0.5...v2.0.6) (2024-05-13)
+
+### What's New
+
+- Classes
+    - Latch
+    - UniqueLock
+    - OnceFlag
+
+- Utilities
+    - callOnce()
+
+### What's Changed
+
+- `CountingSemaphore` constructor now alternatively accepts an initial value.
+- The maximum value for `RecursiveMutex` has changed.
+    - Before: Number.MAX_SAFE_INTEGER
+    - After: (2**31) - 1
+
+### Breaking Changes
+
+- `CountingSemaphore.MAX` and `RecursiveMutex.MAX` constants have been renamed to `.Max`.
+
+## [2.0.5](https://github.com/havelessbemore/semafy/compare/v2.0.4...v2.0.5) (2024-05-12)
+
+### What's New
+
+- Utilities
+    - `tryLock` function for attempted joint locking of multiple locks.
+
+- Errors
+    - `MultiLockError` class to collect and surface errors attempting to lock multiple locks.
+    - `MultiUnlockError` class to collect and surface errors attempting to unlock multiple locks.
+
+### What's Changed
+
+- `SharedMutex.tryLock` and `SharedMutex.tryLockShared` are now non-blocking.
+
+## [2.0.4](https://github.com/havelessbemore/semafy/compare/v2.0.3...v2.0.4) (2024-05-10)
+
+### What's Changed
+
+- Fix bug in `lockGuard`. Mutex unlock was not properly awaited on for mutexes with async unlocking.
+
+## [2.0.3](https://github.com/havelessbemore/semafy/compare/v2.0.2...v2.0.3) (2024-05-10)
+

+    - RecursiveTimedMutex
+    - SharedLock
+    - TimedMutex
+
+- Utilities
+    - lockGuard
+
+## Breaking
+
+Until v2.1.0, breaking changes may be released in patched or minor versions. These will be always be highlighted in the release notes / changelog.
+
+- Remove .request, .requestFor, .requestShared and .requestUntil methods. 
+    - .request should be replaced by lockGuard. 
+    - .requestShared should be replaced by wrapping the shared mutex in a shared lock and then using lockGuard.
+    - There are no replacements for .requestFor and .requestUntil at this time.
+
+- Rename classes
+    - Mutex -> TimedMutex
+    - Semaphore -> CountingSemaphore
+    - MutexError -> LockError
+    - MutexOwnershipError -> OwnershipError
+    - MutexRelockError -> RelockError
+

+
+### Breaking
+Given the very brief period since the previous version, this will be released as a patch, despite breaking changes.
+
+- Removed ability to instantiate classes with Int32Array.
+- Replace .handle getter with .buffer and .byteOffset getters
+- tryLock methods now return false instead of throwing an error if lock already owned.
