Changelog

Version 1.55.0


Released 15 Jul 2024
FeatureMoved style resolving off the Advance call into a task. This will allow parallel style resolving of multiple views. Until completion of the style task, all View APIs that modify the DOM will block to prevent race issues. The block will be removed when the style resolving is further enhanced to become asynchronous and thread-safe. If you experience any issue due to the change, you can use the --synchronous-style-solving view developer option to revert to the old behavior.
FeatureAllow precise updates for collections inside data-binding models
EnhancementAllow SynchronizeModels to run during DOM building
EnhancementEnhanced the font-fit feature with the ability to explicitly set minimum and maximum resulting font size
EnhancementEnhanced the low-level GPU memory info API with extended information about the page resources and their usage
EnhancementUnreal EngineEnhanced the Editor texture statistics reporting to include all GPU resource types
EnhancementAdded optional compositorId argument to elementFromPoint DOM API to allow querying for the topmost element from composited hierarchies
EnhancementUnityAdded a new ‘JavaScript Event Binding’ sample to the Unity3D UPM package
EnhancementUnityImproved the Unity3D Integration and Plugin API Reference documentation
EnhancementUnityImproved the ‘JavaScript Binding’ page in the Unity3D documentation

EnhancementAdded a sample to showcase how to use emojis in a chat input
EnhancementUse a single MSAA texture for the GPU tessellation
EnhancementMultiple improvements of GPU tessellator (Lower CB usage, better batching, fixed 32-bit indexing, single atlas resolve)
APIAnimation end events are fired 1 frame later now, due to animations being ticked asynchronously on the thread executing styling work.
APICompositor API is now called on the thread executing styling work instead on the DOM thread during the Advance call.
APISynchronous resource requests can now be invoked from the thread executing styling work as well and not only from the thread calling Advance.
APIAbort notifications can now come from the thread executing styling work.
APIClients can force resource requests on the Advance calling thread via a view developer option --force-resource-requests-on-the-dom-thread until their resource handlers become thread-safe. Keep in mind that this delays resource loading until the next Advance call.
APIDeprecated SynchronizeModels happening on DOMContentLoaded. Before SynchronizeModels during loading was delaying the synchronization to happen just before the DOMContentLoaded event. The new behavior is to synchronize the models immediately and queue a synchronization on DOMContentLoaded. Future versions will only do the immediate synchronization.
APIRemoved the deprecated font-fit-mode CSS property in favor of coh-font-fit-mode
APIAdded a shorthand CSS property coh-font-fit that allows to set the mode and the limits with a single declaration
APIUnityDeprecated the Library.Initialize overload with the device model as parameter.

Version 1.0.0.6


Released 05 Dec 2018
FeatureUWP Added support for UWP ARM.
FeatureUWP The SDK will now use ChakraCore as JavaScript VM on UWP x86. JavaScriptCore is still the JSVM for UWP x64. This nets about 30% performance increase in JavaScript execution. ChakraCore on UWP x64 will be available in a later release.
FeatureAPI Added initial support for virtual lists to the data binding system. Virtual lists allow users to work on sections of some lists of data instead of the full data. For example, you might want to display only the first 5 items of your in-game store instead of all items. See the docs for engine.makeVirtualList. This release brings support for pagination i.e. splitting your list into pages. Future improvements will add support for predicate filtering and sorting.
FeatureJavaScript can now modify objects exposed by C++. This allows the UI to update game state directly without invoking functions.
FeatureAdded partial support for custom elements across all platforms. Custom elements provide a way for JavaScript devs to create their own HTML elements. Support is partial because new classes can only be derived from HTMLElement.
FeatureAPI Added the ability to dump all currently used images in the UI. This is useful when you want to know which files to package, preload or generate atlases for. See the new method cohtml::View::GetUsedImagesList.
FeatureAdded support for the line-height CSS property.

FixFixed rendering of SVG gradients which were misplaced when under the effects of a transformation (translation, rotation, etc.).
FixFixed a bug which would cause some SVG files no never be loaded if a lot of SVGs were loaded simultaneously at the start of the application.
FixErrors thrown inside event handlers of engine.on are now properly logged across all platforms. Previously, these errors would be silently ignored.
FixInvoking console.log with null or undefined will now produce the same behaviour across all platforms. Previously, some would throw errors, others would log empty strings or empty objects.
