+### Initial support for x86_64
+
+The x86_64 code support has been revived and enabled for qemu. While it started
+as PoC and the only supported platform is an emulator, there's interest in
+enabling additional platforms. It would allow to access more than 4GiB of memory
+at runtime and possibly brings optimised code for faster execution times.
+It still needs changes in assembly, fixed integer to pointer conversions in C,
+wrappers for blobs, support for running Option ROMs, among other things.
