2020.3.34f1 Release Notes

API Changes

  • Editor: Removed: Made Il2CppEagerStaticClassConstructionAttribute internal to avoid conflicts with other definitions outside of the package.

  • IL2CPP: Fixed an issiue to allow blittable, generic value types to be marshaled as delegate parameters. (1348863)

  • IL2CPP: Fixed an issue to ensure that exception handlers are properly sorted internally to avoid code conversion errors with System.Text.Json (and maybe other assemblies). (1400410)

  • License: Increased timeouts of license client and disable signature validation.

  • Networking: Fixed an issue that UnityTLS client API doesn't correctly validate certificates. (1413222)
