Uno Platform v3.1.6 Release Notes

Release Date: 2020-10-23 // over 3 years ago

  • 🚀 The 3.1 release is our 6th release in 2020! In our 2019 survey you had asked to release more often and we hope we have delivered.

    🚀 In year 2019, we had a total of 4 releases and in 2020 we are already up to 6. We also hope to have at least one more release by the end of the year!

    🚀 The 3.1 release is special not only because of the new scenarios it unlocks, but also because of significant community contributions we are able to ship – thanks a lot to @robloo, @dansiegel and @MartinZikmund for your contributions.

    📚 For this 3.1 release, we were able to add over 70 features and close over 140 code and documentation issues. Let’s unpack the release.

    • 🚀 The first preview release of the Linux and Windows 7 support using a new Skia rendering backend. We’ve already started using it on the Uno Calculator, and it’s looking great!
    • The WinUI 2.x TabView and TreeView controls for Skia and WebAssembly, the other platforms are coming. (Thanks @MartinZikmund)
    • ScrollViewer XAML ScrollBars for WebAssembly and Skia
    • 👌 Improvements to the VSIX/dotnet new updates, such as new item templates in the VS, .vsconfig support to suggest VS features to install, and Skia Backend templates.
    • 🏁 The support for StorageFile.GetFileFromApplicationUriAsync, to use large assets packaged with the application, something particularly useful in the WebAssembly context.
    • 👍 The WinUI ColorPicker support (iOS/Android) (Thanks @robloo)
    • 👍 WebAssembly support for Canvas.ZIndex
    • 👌 Support for x:Bind plain C# objects bindings, as well as Bindings.Update()
    • ⚡️ Windows.Globalization.Calendar updates, paving the way for Date and Time pickers
    • 🍎 FolderPicker support for macOS (Thanks @MartinZikmund)
    • BadgeNotifications for Android and iOS (Thanks @MartinZikmund)
    • 👍 Page supports background brushes
    • 🛠 Fixes for NavigationView navigation items binding
    • 👍 Voice over support for WebAssembly

    🚀 And finally, the whole new Prism 8 templates updates for the dotnet new experience.
