Fixed

• Fixed web requests null result in cases when downloaded file failed to open.
• Fixed AsyncUtility.AddCompletionCallback exception when adding new callbacks from another callback.
• Fixed AsyncUpdateSource implementation to allow adding listeners from a callback.
• Fixed AsyncCompletionSource.SetProgress implementation to allow setting progress when the operation is not started.

• Removed (Try)SetExceptions methods/extensions and FromExceptions helpers.
• Removed extension methods of the Animation class.
• Removed WaitAsync extension methods of the Animator class.
• Dropped MovieTexture support.

Added

• AsyncResult is now Task-like type and can be used as async method result value (requires C# 7.2).
• Added new AsyncResult.FromAction overloads.
• Added new SynchronizationContext extension methods (PostAsync, InvokeAsync etc).
• Added extension methods for Socket, WebRequest, Stream BCL classes.

Changed

• Moved BCL extension methods to namespace UnityFx.Async.Extensions (previously they were in namespace UnityFx.Async).

Fixed

• Fixed AsyncResult completion callbacks to be called event if OnCompleted throws.
• Fixed exception not been set for AsyncResult.FaultedOperation and AsyncResult.CanceledOperation.
• Disabled MovieTexture helpers for iOS/Android (as it is not supported on mobiles).

Removed

• Removed AsyncResultQueue.
• Removed AsyncLazy.

Added

• Added convenience overloads for SetException-like methods accepting as error message string.
• Added allocation optimizations for single-threaded applications (particularly for Unity3d). See AsyncResult.DefaultSynchronizationContext for more info.
• Added new overloads for ConfigureAwait extensions accepting continuation options instead of boolean flag.
• Added SynchronizationContext extension methods for Send/Post accepting Action as the delegate.
• Added AsyncResult.Yield static method (workd exactly as Task.Yield).
• Added AsyncUtility.AddFrameCallback helper for scheduling delegates for MonoBehaviour update loop.
• Signed the assembly with a strong name.
• Added performance benchmarks.
• Added sandbox Unity project.

Changed

• Moved several of IAsyncOperationEvents methods to the interface extensions.
• Simplified AsyncLazy interface.

Fixed

• Fixed error handling in AsyncOperationResult.

Removed

• Removed Asset Store samples.
• Dropped Unity 5.0 support (the minimum version supported is now 5.4).
• Dropped WWW support for Unity 2018.3+ (it has been deprecated in Unity).

Added

• Added Play/Wait extension methods for Animation and Animator.
• Added AsyncResult.IsStarted helper property.

Changed

• Changed AsyncResult constructors argument order to avoid ambiguity in some cases.
• Moved the package content to Plugins folder and remove assembly definition file.
• Moved web request related helpers from AsyncUtility to AsyncWww class.
• Changed AsyncUtility.SendToMainThread, AsyncUtility.PostToMainThread and AsyncUtility.InvokeOnMainThread implementation to use ConcurrentQueue for net46+ to avoid unnesesary locks.
• Changed interface of AsyncResultQueue.

Removed

• Removed IAsyncOperationEvents.TryAddCompletionCallback and IAsyncOperationEvents.TryAddProgressCallback methods. These methods are not needed in 99% of cases and may lead to logic errors in multi-threaded environment.

Added

• Added IAsyncOperation.Id property for easy operation identification.
• Added AsyncUtility.GetText and AsyncUtility.GetBytes helpers.
• Added ToTask extensions for AsyncOperation/UnityWebRequest/WWW.
• AsyncResult now implements AsyncContinuation to enable easy operation chaining.

Fixed

• Fixed compile warnings for Unity 2018.2.

Removed

• Removed ToAsyncXxx extension methods for WWW and UnityWebRequest.
• Removed MovieTexture related methods for Unity 2018.2 (the class is deprecated now).
• Removed IAsyncSchedulable interface (it was just another form of IAsyncContinuation).

Added

• Added assembly definition file for Unity 2017.3+.
• Added AsyncResult.FaultedOperation helper.
• Added AsyncUtility.IsMainThread method.

• Added new FromAction overloads.

Changed

• Significantly reduced number of memory allocations when adding continuations.
• Changed signature of the IAsyncContinuation.Invoke method.
• Changed AsyncResult.OnCancel implementation to do nothing (previously it threw NotSupportedException).

Fixed

• Fixed exception when removing listeners while in AsyncUpdateSource.OnError / AsyncUpdateSource.OnCompleted / AsyncUpdateSource.Dispose.
