[2.0.0] - 2025-06-25

Removed

  • Removed Unity.AppUI.Core.AppUI.DismissAnyPopups method. Popups are now registered per Panel element.
  • Removed Canvas.scrollDirection property in order to support correctly the scroll direction set in the Operating System's preferences.
  • Removed programatic construction of RadioGroup with IList object. Since App UI offers the possibility to have Radio component as deep as you want in the visual tree compared to its RadioGroup ancestor, we wanted to limit conflicts between construction kinds.
  • TextFieldExtensions.BlinkingCursor extension method has become obsolete. Please use the new BlinkingCursor manipulator instead.
  • Removed intrusive Debug.Log calls from Platform class on Windows platform.
  • Removed warning message when using Single selection type in an overflown ActionGroup.
  • Removed EventBaseExtensionsBridge class
  • [Canvas] Removed applying cursor styles during pointer events as it was too costly in terms of performance.
  • Removed the Popup message Handler that was used to dispatch the display or dismissal of Popups. While this removes thread safety, it fixes issues with ordering of events to dismiss popups.

Changed

  • Refactored SliderBase and BaseSlider for performance improvements and better features. The RangeSliderBase class has been removed and RangeSliderFloat/RangeSliderInt are now derived from SliderBase directly.
  • The Platform, AppUIInput and GestureRecognizer classes now use pre-allocated buffers to deal with Touch events in a single frame, and expects a ReadOnlySpan<AppUITouch> type to work with instead of AppUITouch[].
  • Refactored switch statement builder for Redux slice construction.
  • The NavDestination node now uses a NavDestinationTemplate as a delegate to create and set up a INavigationScreen when reaching this destination.
  • Subscribing to a Redux Store returns a IDisposableSubscription object instead of a method. You can dispose it by calling its Dispose method.
  • Changed DialogTrigger.keyboardDismissDisabled to DialogTrigger.keyboardDismissEnabled for consistency.
  • Make Host optional when intializing an App implementation.
  • Renamed IUIToolkitApp.mainPage property into IUIToolkitApp.rootVisualElement for more clarity.
  • Moved NavDestination specific settings such as showAppBar inside the new DefaultNavDestinationTemplate.
  • Replaced ClickEvent action in MenuItem builder by an EventBase action
  • Refactored completely the DropZone UI element. Now the DropZone doesn't embed any logic, but uses a DropZoneController instead. You can access this controller via DropZone.controller property and attaches a callback method to accept dragged objects and listens to drop events.
  • Changed ticks related properties in Slider components with a new marks property. To configure marks you can you the new step property or directly set your customMarks
  • Changed StoryBookEnumProperty class to become a generic type. You need to specify the Enum type as typedef parameter.
  • Refactored Redux API fore more flexibility. See the migration guide in the package documentation.
  • Renamed Popup.parentView to Popup.containerView for more clarity.
  • Complete rewrite of the SplitView component. The SplitView is no more a derived from TwoPaneSplitView from UI-Toolkit, but a full custom component that supports any number of panes.
  • Scrollable manipulator now stops the propagation of WheelEvent. This affects only the Drawer and SwipeView elements.
  • Defer checking Popup's container candidate when the Popup is about to be shown, instead of during Popup creation.
  • Use resolvedStyle.translate instead of transform.position to move elements such as the Canvas container.
  • Changed DropZoneController to support any VisualElement as target instead of a DropZone element.
  • Changed the Text element inside the ColorField to become a selectable text.
  • Others assembly modules such as Redux, MVVM and Navigation has been configured to be auto-referenced in the Unity project's assemblies.
  • Refactored every native plugin provided by the package.
  • Updated App UI Native plugins for MacOS and iOS.
  • Refactored the styling of Chip UI element.
  • Moved Toast animation logic from code to USS.
  • Changed the Trackpad sample project to work properly with the new events coming from the new Gesture Recognizer System.
  • Refactored the SwipeView element logic, without impacting the public API.
  • The RadioGroup component uses a string type for its value property. This string value is equal to the currently checked Radio component's key property.
  • The Toast.AddAction method will now ask for a callback that takes a Toast object as argument (instead of no argument at all). This will give you an easier way to dismiss the toast from the action callback.
  • You can now pass an autoDismiss argument to the Toast.AddAction method. This will automatically dismiss the toast when the action is triggered. This argument is optional and defaults to true for backward compatibility.
  • Rewrite of App UI shaders in pure HLSL instead of legacy CG language.
  • Changed MemoryUtils.Concatenate implementation to not use variadic parameters and avoid implicit allocations.
  • Replaced the MacOS native plugin by a .dylib library instead of a .bundle one.
  • App UI shaders are now optionally embedded in Player builds. You can change this setting in your main App UI settings instance. The default value is true.
  • Storybook stories are now sorted alphabetically.
  • Upgraded the old Drag And Drop Sample to use the refactored DropZone and the new Drag And Drop system.
  • Renamed Create/App UI/Settings menu item into Create/App UI/App UI Settings
  • Changed the way MarkDirtyRepaint is scheduled on elements containing animated textures (check properly for visibility).
  • Replaced the dropdown with an ObjectField to pick an available App UI settings asset.
  • The Canvas now uses Experimental.Animation system from UI-Toolkit for its damping effect when releasing the mouse with some velocity. That replaces the previous implementation that was using the VisualElementScheduledItem.

  • Changed the styling of primary action buttons in AlertDialog UI element.
  • Changed the Context API to propagate contexts over internal components hierarchies and not just the high-level hierarchy (via contentContainer).

  • CircularProgress and LinearProgress elements with Indeterminate variant won't be marked as DirtyRepaint if they are off-screen anymore.
  • Refactored the dispatch process of Redux AsyncThunk.

  • Added formatFunction along with formatString and grouped them into a new IFormattable<TValueType> interface. The formatFunction will give you the possibility to customize entirely the string formatted value of a given TValueType.
  • Added a RestrictedValuePolicy on slider components where you can choose if the slider can take a value related to the step or customMarks with modifier keys or not.

You can always switch between settings via the Project Settings > App UI settings pane.
  • Added Unity.AppUI.UI.Chip.deletedWithEventInfo and Unity.AppUI.UI.Chip.clickedWithEventInfo events.
  • Added trailing-icon property in ActionButton component.
  • Added damping-effect-duration property in Canvas element. The default value is 750ms.
