+Changes to the RISCV Target
+---------------------------------
+
+The RISCV target is no longer "experimental"! It's now built by default,
+rather than needing to be enabled with ``LLVM_EXPERIMENTAL_TARGETS_TO_BUILD``.
+
+The backend has full codegen support for the RV32I and RV64I base RISC-V
+instruction set variants, with the MAFDC standard extensions. We support the
+hard and soft-float ABIs for these targets. Testing has been performed with
+both Linux and bare-metal targets, including the compilation of a large corpus
+of Linux applications (through buildroot).
