Fix: Android status bar icons become unreadable after enabling UseMaterial3 in .NET MAUI 10

MAUI 10.0.100 picks status bar icon colors from colorPrimary, which is the opposite brightness of the Material 3 surface, so you get white on white or black on black. Update Microsoft.Maui.Controls to 10.0.101 or later, or reset AppearanceLightStatusBars in MainActivity.

Fix: MediaPicker.CapturePhotoAsync returns a PNG instead of a JPEG in .NET MAUI 10

On iOS, MAUI 10 re-encodes camera photos as PNG whenever CompressionQuality is 90 or higher and no MaximumWidth/Height is set, which includes the default. Set CompressionQuality to 89 or lower, or add a MaximumWidth on iOS only.

MessagePack 3.1.9 and 2.5.303 Fix a 32 KiB Payload That Allocates 120 MiB

Polly 8.8 Reloads a Resilience Pipeline From Your Own IOptionsMonitor

Polly 8.8.0 adds EnableReloadsWithMonitor, so a resilience pipeline can hot-reload from a feature flag or remote config monitor that is not registered in DI. A probe shows the rebuild, and one trap: context.GetOptions still reads the DI monitor and returns defaults.
