WinUI 3 in Windows App SDK 1.8.9

This release of WinUI 3 ships as part of Windows App SDK 1.8.9. To use it in your app, install the Microsoft.WindowsAppSDK 1.8.260529003 NuGet package.

1.8.9 is a stable servicing release for 1.8. The WinUI changes in this release are two reliability fixes:

• Fixed a memory leak in ItemsRepeater where recycled elements were never garbage collected due to a reference cycle through the RecyclePool, which could also cause crashes in InvalidateChildrenMeasure.
• Fixed a potential crash when releasing touch contacts in a ScrollViewer before scrolling.

For the full set of changes, see the Windows App SDK 1.8.9 release notes.
