• Fixed a potential crash trying to restore focus if a window activation event is delivered for a window which is closing.
• Fixed a performance regression introduced in WinAppSDK 1.6 due to WinUI binaries missing some linker optimizations.
• Fixed a small performance issue when creating multiple WinUI windows/islands.
• Fixed a potential crash if ProgressBar::SetProgressBarIndicatorWidth is called on a ProgressBar which is not in the tree.
• Fixed a potential crash caused by CPopup::EnsureBridgeClosed sometimes triggering reentrancy.
