 - When using `ExtendsContentIntoTitleBar = true`, clicks at the top-left corner of the window by default always show the system window menu (Minimize/Close/etc.) rather than letting the pointer input through to the content of the window. This, for example, means that a Back button in that area of the titlebar will not work. A workaround for this issue is to set `AppWindow.TitleBar.IconShowOptions = Microsoft.UI.Windowing.IconShowOptions.HideIconAndSystemMenu` on the Window's AppWindow.
 - There are some new continuable exceptions when hiding `ShouldConstrainToRootBounds="False"` popups/flyouts. That includes hiding tooltips, as reported here: [Dismissing a tooltip throws 4 native exceptions · Issue #8699 · microsoft/microsoft-ui-xaml (github.com)](https://github.com/microsoft/microsoft-ui-xaml/issues/8699)
 - In 1.4, the min/max/close caption buttons for `ExtendsContentIntoTitleBar = true` are now drawn by AppWindow rather than XAML. This is by design, but it can impact apps that were overriding XAML's internal styles to hide or do extra customization of these buttons, such as in this report: [Cannot hide caption button on titlebar · Issue #8705 · microsoft/microsoft-ui-xaml (github.com)](https://github.com/microsoft/microsoft-ui-xaml/issues/8705)

Because of this issue and because .NET 8 has not officially released yet, the Windows App SDK 1.4 does not officially support .NET 8. However, if you would still like to target the pre-release version of .NET 8 with this version of the App SDK, we recommend the following steps:
