FNA 26.08 Released

FNA 26.08 is out, and it reads like a compatibility-and-correctness release rather than a feature sprint. The engine updates its FNA3D and FAudio backends to 26.08, while also improving design-time conversion behavior, parser flexibility for list strings, and converter initialization across the board.

Most of the work here is in the “make it behave more like XNA, and stop surprising developers” bucket. There are widespread accuracy fixes for Equals, GetHashCode, and Dispose implementations, along with more input-parameter validation exceptions. GameComponent disposal now removes the component from Game.Components, and protected OnXYZ methods now fire their matching events properly, which should matter to anyone relying on lifecycle hooks.

Several compatibility fixes target math, input, graphics, and audio edge cases. MathHelper now handles NaN in Min/Max per IEEE rules, while ToDegrees/ToRadians has been tuned to match XNA’s floating-point precision. Keyboard support has been fixed for Decimal, VolumeMute, and OemBackslash; Mouse scroll tracking now uses float internally; Effect indexers return null for out-of-range access; and DisplayMode.AspectRatio no longer divides by zero when height is zero.

There are also a few behavior changes worth checking during upgrades. PresentationParameters now defaults Adapter to GraphicsAdapter.DefaultAdapter and IsFullScreen to true, while Microphone.IsHeadset now defaults to true and SDL3_FNAPlatform gets fixes for default microphone selection and playback state. The release also trims generated IL for small efficiency gains, so teams...
