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.
FeatureAdded support for exposing objects containing std::pair, std::map and std::unordered_map to the UI.
EnhancementAPI Added support for the window.onresize event.

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.
FixFixed a crash when calling cohtml::System::Uninitialize while a video was still playing.
FixFixed a bug which would cause videos to sometimes stop spuriously.
FixFixed a bug which would cause some SVGs to be rendered incorrectly.
