  • Input: Update mouse position when it is outside of rendered area in Windows standalone.
  • iOS/IL2CPP: Avoid adding includes and methods (for method declaration includes) for types generated to terminate generic type recursion. iOS/IL2CPP: Correct an error in generated code when a constrained generic parameter type is used in a nested lambda expression.
  • iOS/IL2CPP: Correct code generation for a generic type with another generic type as a constraint when the generic parameter for the constraint is a value type.
  • iOS/IL2CPP: Corrected the implementation of the ldvirtftn opcode for types using a constrained generic generic parameter.
  • iOS/IL2CPP: Correctly invoke an action pointing to an extension method.
  • iOS/IL2CPP: Emit memory barriers to ensure the correct acquire and release semantics are enforced for loads and stores of volatile fields.
  • iOS/IL2CPP: Ensure that background threads which are not explicitly joined have their resources freed so that the runtime does not leak thread handles.

  • iOS/IL2CPP: Implement embedded resources for IL2CPP.
  • iOS/IL2CPP: Prevent a crash when a thread with a name is finalized.
  • iOS/IL2CPP: Prevent IL2CPP from throwing an exception at conversion time for a generic type deriving from a generic interface.
