React Native Windows 0.67.0-preview.1

[NickGerleman]

We're excited to release our first preview build of react-native-windows 0.67! There have been many changes to both react-native-windows and react-native itself and we would love your feedback on anything that doesn't work as expected.

How to upgrade

You can view the differences between different versions of C++ applications using a special version of React Native Upgrade Helper.

Upgrade helper does not yet support C# projects or projects using experimental features. It is recommended to generate a new project using react-native-windows-init for projects not supported by Upgrade Helper.

What's New

• View manager pointer hooks: View managers can now implement IViewManagerWithPointerEvents to customize handling of pointer events that would normally be propagated to React as touch events.

• Accessible images: Images with the accessible prop set will now show up to screen readers, including support for accessibilityLabel.

• Unsigned by default: We previously included a temporary AppX signing certificate when creating a new project. You no longer need to check in a certificate, and only need to use one when publishing your application.

• RNW version queries: Libraries targetting multiple versions of react-native-windows can now specialize behavior dependant on the version of RNW the library is compiled with. RNW_AT_LEAST and RNW_LESS_THAN macros are exposed to C++ community modules targetting RNW 0.67+.

• Bug-fixes and improvements: We've made many more fixes across the platform. Expect less crashes, more correct behavior, and quality of life improvements for developers.

Breaking Changes

• AppX deployment: UWP applications without certificates need to be deployed using loose file registration. This is handled for you if you use Visual studio, or run-windows, but may require changes if you are using custom logic for deployment.
