+
+The RISC-V ISA privledge specification version 1.09.1 has been deprecated.
+QEMU supports both the newer version 1.10.0 and the ratified version 1.11.0, these
+should be used instead of the 1.09.1 version.

+
+@subsection RISC-V ISA CPUs (since 4.1)
+
+The RISC-V cpus with the ISA version in the CPU name have been depcreated. The
+four CPUs are: ``rv32gcsu-v1.9.1``, ``rv32gcsu-v1.10.0``, ``rv64gcsu-v1.9.1`` and
+``rv64gcsu-v1.10.0``. Instead the version can be specified via the CPU ``priv_spec``
+option when using the ``rv32`` or ``rv64`` CPUs.
+
+@subsection RISC-V ISA CPUs (since 4.1)
+
+The RISC-V no MMU cpus have been depcreated. The two CPUs: ``rv32imacu-nommu`` and
+``rv64imacu-nommu`` should no longer be used. Instead the MMU status can be specified
+via the CPU ``mmu`` option when using the ``rv32`` or ``rv64`` CPUs.
