5.3.31

Hello Rider lovers!! We are bringing many additions to Uno Platform in this 5.3 release, but the highlight is official support for JetBrains Rider, as well as improved Hot Reload experience, two new UI controls (ItemsView, SelectorBar), exciting new options for Fonts, and adding support for SkiaSharp 3 preview, to name a few.

We’ve also spent significant effort into further simplifying Uno Platform versioning, so that you can spend more time coding and less time fiddling with NuGet packages. Lastly, we are continuing support for .NET 9 Preview releases and retiring support for .NET 7 as it is now officially not supported by Microsoft any longer.
