Release of Graphene SGX: Supporting native Linux application in Intel SGX enclaves. Most applications are supported. Some features may still be buggy. Improving portability of Graphene: Eliminating GCC-ism of the host-generic code. Easier to port to non-Posix platform (e.g., Windows without Cygwin).
