Changes since 10.1.0:

• Mono's handling of arrays with no defined size in native wrappers now treats them as having a size of 1, matching .NET Framework. This fixes a crash in some winforms applications when used with accessibility tools.
• Fixed an assertion failure when using the undocumented "VtblGap" runtime feature. Terraria's multiplayer server encounters this.
• Modified FNA's Texture2D class to be xml-serializable. This is used (but not really) by Meridian: New World. It attempts to serialize a class containing a null Texture2D field, but just having the field is enough to cause an error.
• Implemented some Microsoft.DirectX.DirectInput.Device methods used by the Sega Rally launcher.
• Technical
  • Some warning fixes in WpfGfx to support newer llvm-mingw.
  • mono-basic has been merged into Framework Mono.
• Upstream updates
  • SDL to 3.2.20
  • FNA to 25.08, plus a few additional commits with fixes for Galactic Arms Race on NVidia GPUs and Ring Runner.
  • llvm-mingw to 20250709
