================
Comment at: llvm/docs/ReleaseNotes.rst:163
 * The ``lp64s`` ABI is supported now and has been tested on Rust bare-matal target.
+* An target feature ``ual`` is introduced to allow unaligned memory accesses and
+  this feature is enabled by default on generic 64bit processors.

Thanks. I will modify it later.

> Target feature is internal and mentioning it in release notes may be excessive (if we do, there are too many to enumerate ...). I think we can omit mentioning the target feature. Focusing on the behavior about the user-facing `-m[no-]unaligned-access` is more useful.
I think it depends on the different users we are targeting. Command line options like `-m[no-]unaligned-access` are targeting clang users while target features are targeting llvm users.
