 are missing:
 
-* Generic Associated Types (1.65.0)
-
-* ``CStr::from_bytes_with_nul()`` as a ``const`` function (1.72.0).
-
-* "Return position ``impl Trait`` in Traits" (1.75.0, blocker for including
-  the pinned-init create).
-
 * inline const expression (stable in 1.79.0), currently worked around with

-It is expected that QEMU will advance its minimum supported version of
-rustc to 1.77.0 as soon as possible; as of January 2025, blockers
-for that right now are Debian bookworm and 32-bit MIPS processors.
-This unfortunately means that references to statics in constants will

 QEMU also supports version 0.60.x of bindgen, which is missing option
 ``--generate-cstr``.  This option requires version 0.66.x and will
 be adopted as soon as supporting these older versions is not necessary
