Ver.2.0.13

on GitHub

First stable release of UniTask v2.
It has many improvement and some breaking changes from v1.

New Features

• Almost all UniTask methods and async method automatically reuse(zero allocation) and reduced heap allocation size
• Asynchronous LINQ, UniTaskAsyncEnumerable standard factory and all linq operators and Unity specified factory generator
• uGUI component has ***AsAsyncEnumerable that converts event to async stream.
• All async triggers(Cysharp.Threading.Tasks.Triggers) implements IUniTaskAsyncEnumerable<T>
• Stacktrace in PlayerLoop shows current PlayerLoopTiming
• Available .NET Core package in NuGet
• Improved UniTaskTracker Window, enable a jump to the source file and TaskName displays generics type name
• DOTween support in default(require to com.demigiant.dotween import from OpenUPM or define UNITASK_DOTWEEN_SUPPORT)
• Addressable support in default(AsyncOperationHandle and AsyncOpereationHandle<T> as awaitable)
• UniTaskCompletionSource can reuse by .Reset()
• New last PlayerLoopTimings (PlayerLoopTiming.LastPostLateUpdate is same as WaitForEndOfFrame)
• New AsyncReactiveProperty, AsyncReadOnlyReactiveProperty, that similar as ReactiveProperty in UniRx
• New Channel.CreateSingleConsumerUnbounded, that is equivalent to System.Threading.Channels, similar as go channel
• TaskPool to set/monitor pooling size by TaskPool.SetMaxPoolSize, TaskPool.GetCacheSizeInfo

New Methods

• Add UniTask.Preserve, it converts to allow multiple await
• Add UniTask.WaitUntilCanceled
• Add UniTask.Create
• Add UniTask.Defer
• Add UniTask.Action/UnityAction
• Add JobHandle.WaitAsync
• Add CancellationToken.WaitUntilCanceled extension method
• Add UnityEvent<T> and InputField AsyncEventHandler and extensions
• Add WithCancellation method to all async operation extensions

Changed from UniTask v1

• Namespace change: UniRx.Async -> Cysharp.Threading.Tasks
• All UniTask/UniTask<T> can not await twice(will throw exception), Reusable Promise is discontinuance
• All UniTask Factory method(such as UniTask.Delay) run immediately(same as standard Task, previously it does not run before call await)
• All Trigger method combinates GetAsync***Trigger and Get***AsyncHandler and ***Async.
• UniTask.Lazy returns AsyncLazy<T>
• UniTask accepts IUniTaskSource instead of IAwaiter
• UniTask.WhenAny return type is changed to (int winArgumentIndex, T1 result1, T2 result2, ...)
• UniTask.WhenAll's tuple does not use specified name
• UniTaskScheduler.UnobservedExceptionWriteLogType's default is changed to LogType.Exception
• UniTaskVoid can not await
• IObservable<T>.ToUniTask parameter order changed from CancellationToken cancellationToken, bool useFirst to bool useFirst, CancellationToken cancellationToken
• UniTask.VoidAction is renamed to UniTask.Action
• UniTask.DelayFrame return type is changed from UniTask<int> to UniTask
• UniTask.Void/Action/UnityAction type is changed from Func<UniTask> to Func<UniTaskVoid>
• Removed ConfigureAwait method from all async operation extensions(renamed to ToUniTask)
• Removed new UniTask(factory), use UniTask.Create or UniTask.Lazy instead
• UnityWebRequest's AsyncOperation calls UnityWebRequest.Abort() when detect canceled
• JobHandle await extension does not accept CancellationToken
• Lower Unity support version is changed to 2018.4.13f1
• Modified directory structure, under Runtime and Edtior directory to follow standard UPM design
