+QEMU supports rustc version 1.83.0 and newer.  The following features
+from relatively new versions of Rust are not used for historical reasons;
+patches are welcome:
 
 * inline const expression (stable in 1.79.0), currently worked around with
   associated constants in the ``FnCall`` trait.
 
-* associated constants have to be explicitly marked ``'static`` (`changed in
+* associated constants are still explicitly marked ``'static`` (`changed in
   1.81.0`__)
 
-* ``&raw`` (stable in 1.82.0).  Use ``addr_of!`` and ``addr_of_mut!`` instead,
-  though hopefully the need for raw pointers will go down over time.

-  crate, which is planned for inclusion in QEMU, but it can be easily patched
-  out.
